Magnitude - A measure of the strength of an earthquake or strain energy released by it, as determined by seismographic observations. This is a logarithmic value originally defined by Charles Richter (1935). An increase of one unit of magnitude (for example, from 4.6 to 5.6) represents a 10-fold increase in wave amplitude on a seismogram or approximately a 30-fold increase in the energy released. In other words, a magnitude 6.7 earthquake releases over 900 times (30 times 30) the energy of a 4.7 earthquake - or it takes about 900 magnitude 4.7 earthquakes to equal the energy released in a single 6.7 earthquake! There is no beginning nor end to this scale. However, rock mechanics seems to preclude earthquakes smaller than about -1 or larger than about 9.5. A magnitude -1.0 event release about 900 times less energy than a magnitude 1.0 quake. Except in special circumstances, earthquakes below magnitude 2.5 are not generally felt by humans. - USGS Earthquake glossary

TMP - The Maine Project. (Formerly known as The Recreational Corridor) The Appalachian Mountain Club is working on a new, model project for outdoor recreation and land protection in Maine. In early June, Gerry Whiting, AMCs Special Projects Manager in Maine, and I held meetings in Portland and Bangor to obtain input from AMC members on the project's concept. While turnout was not as high as we hoped, we did get feedback that's helping to shape the project. One important thing we learned is that the name we have been using, the Recreational Corridor, does not adequately describe the scale of the project. It's a lot more than just recreation. While we have not yet come up with a new name (we're calling it the "Maine Project" for now), the following description of its goals and objectives will let you know what it's all about. The Maine Project is being designed to provide a variety of opportunities for non-motorized, backcountry recreation; for example, hiking, paddling, cross-country skiing, and mountain biking. It will ensure continued public access to large tracts of forestland in the North Woods. The project will be part of a landscape that includes sustainable forestry and protection of ecologically significant lands. We anticipate the timeline of this project to unfold slowly, and be a focus for AMC activities for next 50-100 years. Through this project, we hope to: provide and protect recreational access to the North Woods; create new, and needed, long-distance and day hiking opportunities; create opportunities for quiet paddling and backcountry, nordic skiing, within a framework of already existing uses, such as fishing and hunting; work with conservation partners to ensure protection of important wildlife habitat; provide a physical base for environmental education, especially for school children; provide for low-impact backcountry overnight facilities; protect jobs and ensure the economic viability of Maine's forest land by supporting a model sustainable forestry project. As this project is still very much in its early stages, it will benefit from your continued input. Feedback received so far indicates members are very interested in the AMC playing a lead role to protect North Woods land from development and to ensure continued public access. Members also feel wilderness protection should be an important part of the project mix; that we should create new opportunities for multi-day hiking, paddling, and nordic skiing; that any facilities or camps should be used for many purposes, including environmental education; and that we should work with existing users, such as snowmobilers and sportsmen, to work out compatible use arrangements. Gerry is currently talking with potential partners and looking for land that we might purchase outright or acquire some less-than-full-title interest in (an easement). We are very open to the possibilities for this project. As Maine-based AMC staff, Gerry and I look forward to keeping our members informed about the project as it progresses, and welcome members, the Chapter board and its committees to become involved in this project. The AMC views the Maine Project as an important investment in Maine, the Northern Forest, and ensuring a balance between recreation, conservation, education and sustainable forestry. http://home.gwi.net/amcmaine/articles/article53.htm 

Mainland/Rimland Framework - Twofold regionalization of the Middle American realm based on its modern cultural history. The Euro-Amerindian mainland stretching from Mexico to Panama (except for the Caribbean coastal strip), was a self-sufficient zone dominated by hacienda land tenure. The Euro-African Rimland, consisting of that Caribbean coastal zone plus all of the Caribbean islands to the east, was the zone of the plantation that heavily relied on trade with Europe and North America.

Mainstream Agriculture - See Conventional Agriculture.

Maintenance - Refers to an institution or statistical area which has or has been given the responsibility for maintaining and/or updating or revising the classification. Refer also to Custodian. (UN)

Maintenance and Construction - The Forest Service has adopted new common terms and definitions for maintenance and construction based on standards developed by the Federal Accounting Standards Advisory Board. These generic terms are now being applied in inventorying, budgeting, and accounting for all fixed assets under Forest Service jurisdiction, including the National Forest transportation system. The terms and definitions used in FSM 7705, though slightly different, are not inconsistent with the new common financial management terms and their definitions. The agency is assessing all its transportation directives to determine what changes in Forest Service Manual and Handbook terminology are needed. However, this effort exceeds the scope of these revisions to road management directives. - USDA Forest Service

Maintenance (Cost) Valuation (environmental accounting) - Method of measuring imputed environmental (depletion and degradation) costs caused by economic activities of households and industries. The value of the maintenance cost depends on the avoidance, restoration, replacement or prevention activities chosen. (UN)

Major Land Resource Area (MLRA) - Major land resource areas are geographically associated land resource units delineated by the Natural Resources Conservation Service and characterized by a particular pattern that combines soils, water, climate, vegetation, land use, and type of farming. There are 204 MLRAs in the United States, ranging in size from less than 500,000 acres to more than 60 million acres. Geographically associated land resource units with particular patterns of soils, climate, vegetation types, water resources, and land uses.

Major Land Resource Areas - MLRAs are geographic areas that have relatively homogeneous patterns of soil, climate, water resources, land use and type of farming. MLRAs can be one continuous area or several separate nearby areas. MLRAs are designated by Arabic numbers and identified by a descriptive geographic name. Some MLRAs are designated by an Arabic number and a letter because previously established MLRAs have been divided into smaller, more homogeneous areas. [Source: USDA-SCS 1982 NRI]

Major Plant Grouping - An aggregation of plant associations with similar management potential and with the same dominant late seral conifer species and the same major early seral species. Late seral rather than climax species are used because late seral species are usually present rather than climax communities and because most old-growth plant communities on BLM-administered lands are made up of late seral species rather than climax species in the upper canopy.

Malnutrition - A condition caused by an imbalance between what an individual eats and what is required to maintain health. The word literally means 'bad feeding' and can result from eating too little, but may also imply dietary excesses or an incorrect balance of basic foodstuffs such as proteins, fats and carbohydrates. A deficiency (or excess) of one or more minerals, vitamins or other essential ingredients in the diet may arise from the inability to digest food properly as well as from actually consuming an unbalanced or inadequate diet. Malnourished people are more vulnerable to infection, disease and general ill health. Poverty is the most immediate indirect cause of malnutrition in both the developed and developing worlds.

Mangroves - Salt-tolerant trees and shrubs which form dense thickets and low forests on coastal mudflats, salt marshes and estuaries throughout the tropics. Mangroves fringe over half of all tropical shores and are typically associated with river mouths where the water is shallow and the sediment levels high. They form one of the most diverse of all ecosystems and provide a unique habitat for fish, invertebrates and plants. Mangroves also play an important role in desalinating seawater and are one of the major factors in stabilizing shorelines. Throughout the tropics mangroves are under threat from clear-cutting, charcoal production, sand and shale mining, land reclamation for agriculture or aquaculture and coastal pollution. (UNESCO)

(UN) Land that is of poor quality and largely unsuitable for cultivation due to its nutrient deficiencies, dryness or susceptibility to erosion. Marginal land is particularly prone to further degradation and even desertification if used for agricultural purposes. However, in many parts of the world people are forced into using these less productive and fragile areas because they may have been displaced by development projects, wars or simply because the needs of the population in an area have exceeded the productivity and availability of arable land.

Marine Mammal Protection Act of 1972 (MMPA), 16 U.S.C. 1361-1421h, October 21, 1972, as amended 1973, 1976-1978, 1980-1982, 1984, 1986, 1988, 1990, 1992-1994 and 1996. - The Act establishes a federal responsibility to conserve marine mammals, with management vested in the Department of Commerce for cetaceans and pinnipeds other than walrus. The Department of the Interior is responsible for all other marine mammals, including sea otter, walrus, polar bear, dugong and manatee. The Act generally assigns identical responsibilities to the Secretaries of the two departments. The Act establishes a moratorium on the taking and importation of marine mammals and marine mammal products. The Secretary may issue permits for taking and importation for scientific research, public display, photography for educational or commercial use, enhancing the survival or recovery of a species, or importation of polar bear parts (other than internal organs) taken in sport hunts in Canada. Permit applications, except for polar bear parts, must first be reviewed by the Marine Mammal Commission and the Committee of Scientific Advisors on Marine Mammals. The Secretary can waive these requirements and allow taking and importing in accordance with the purposes and policies of the Act, if the Secretary certifies that the marine mammals were taken in their country of origin in a manner consistent with this Act. With limited exceptions, no permits may be issued for the taking or importation of a marine mammal designated as depleted. Incidental taking in commercial fishing operations is allowable either by permit or authorization by the Secretary. The immediate goal is the reduction of incidental kill or incidental serious injury of marine mammals in commercial fishing to insignificant levels approaching a zero mortality and serious injury rate. The Secretary of the Treasury must ban the importation of commercial fish or products from fish caught with commercial fishing technology that results in the incidental kill or serious injury of marine mammals in excess of U.S. standards, and must require reasonable proof from exporting countries of the effects of their technology on these mammals. Specific documentary evidence is required from nations exporting yellowfin tuna harvested with purse seines in the eastern tropical Pacific Ocean. Intermediary nations must certify and provide proof that they have not imported any yellowfin tuna or products that are subject to the U.S. importation ban. Exporting nations also must provide evidence that fish were not harvested with large-scale driftnets. The Act generally does not apply to measures to deter a marine mammal from endangering personal safety or damaging personal property, as long as the measures do not seriously injure or kill the animal. The Secretary must publish guidelines on nonlethal ways to deter marine mammals. It is not a violation of the Act to take a marine mammal if imminently necessary to save a life, provided the taking is reported to the Secretary within 48 hours. The Act sets out procedures for the Secretary to allow incidental taking of small numbers of marine mammals through a specific activity in a specified geographic region, upon certain findings and with protective restrictions. This authorization requires public notice in the affected local communities. The Secretary also may allow incidental taking of depleted marine mammals during commercial fishing, if the impact is negligible, a recovery plan is developed and a monitoring program is established. The Act does not apply to the taking of marine mammals by an Indian, Aleut or Eskimo who resides in Alaska and dwells on the coast of the North Pacific Ocean or the Arctic Ocean, if the taking is done in a nonwasteful manner and is for subsistence purposes or for creating and selling authentic native handicrafts and clothing. These takings may be regulated by the Secretary, however, if the marine mammal is depleted. 1371.

Marine Protected Area (MPA) - Executive Order 13158 defines marine protected areas (MPAs) as "any area of the marine environment that has been reserved by Federal, State, territorial, tribal, or local laws or regulations to provide lasting protection for part or all of the natural and cultural resources therein." There are many different types of MPAs in U.S. waters. A marine protected area has come to mean different things to different people, based primarily on the level of protection provided by the MPA. Some see MPAs as sheltered or reserved areas where little, if any, use or human disturbance should be permitted. Others see them as specially managed areas designed to enhance ocean use. Many accept the definition developed by the World Conservation Union: "Any area of the intertidal or subtidal terrain, together with its overlying water and associated flora, fauna, historical and cultural features, which has been reserved by law or other effective means to protect part or all of the enclosed environment" (IUCN, 1988; Kelleher, 1999). Not too different is the definition in Marine Protected Areas Executive Order 13158. This defines an MPA as "any area of the marine environment that has been reserved by Federal, State, territorial, tribal or local laws or regulations to provide lasting protection for part or all of the natural and cultural resources therein" (Federal Register, 2000). Under this broad definition, a wide variety of sites could be considered as MPAs. There are many different types of MPAs in the United States. For example, U.S. MPAs may include national marine sanctuaries, fishery management zones, national seashores, national parks, national monuments, critical habitats, national wildlife refuges, national estuarine research reserves, state conservation areas, state reserves, and many others. MPAs have different shapes, sizes, and management characteristics, and have been established for different purposes. MPAs are used as management tools to protect, maintain, or restore natural and cultural resources in coastal and marine waters. They have been used effectively both nationally and internationally to conserve biodiversity, manage natural resources, protect endangered species, reduce user conflicts, provide educational and research opportunities, and enhance commercial and recreational activities. - National Oceanic and Atmospheric Administration, U.S. Department of Commerce

Marine Protected Area List Site Working Definition - Taken together, these criteria provide the basis for the MPA List Site Working Definition. A. Area - To be included in the MPA List, the site: Must have defined geographical boundaries or a definable geographic location and, a) may or may not be associated with the underlying seabed and b) may be of any size, but must be a subset of the U.S. federal, state, territorial, local or tribal waters. This working definition excludes: Areas of the U.S. Exclusive Economic Zone that are covered under legal authorities but that have no distinct boundaries with specific authorities for resource protection. Areas subject to generic resource management authorities linked to habitat type but without specific locations. Areas subject to species-specific conservation authorities that are not focused on a definable geographic area. B. Marine - To be included in the MPA List, the site: Must encompass: a) areas of the oceans, coastal waters, bays and/or estuaries; or b) the Great Lakes and their connecting waters. Must have a marine component, which may include an intertidal area and may have an associated land (terrestrial) component. This working definition excludes: Strictly freshwater areas outside the Great Lakes that contain marine species at certain seasons or life history stages. C. Reserved - To be included in the MPA List, the site: Must be authorized by some form of federal, state, territorial, local or tribal law or regulations. This working definition excludes: Privately created and maintained marine areas. D. Lasting - To be included in the MPA List, the site: Must provide year round (12 months) protection. Must be established with an expectation of, or at least the potential for, permanence. Areas with a sunset clause must provide a minimum of four years of continuous protection and must have a specific mechanism to renew protection at the expiration of the sunset period. This working definition excludes: Areas subject to emergency measures designated for fisheries or other purposes. E. Protection - To be included in the MPA List, the site: Must have existing laws/regulations that apply to the MPA and that were designed to afford increased protection to part or all of the natural and cultural resources therein, beyond any general protections which apply outside the MPA. This working definition excludes: Mitigation sites and other temporarily closed areas. Areas set aside to avoid fishing gear conflicts. Areas subject to single species management measures that do not have demonstrable benefits to a broader array of species or habitats. Areas subject to fisheries quota management tools. In addition, the term cultural resources was further defined for those MPAs with these resources: Cultural resources means any historical or cultural feature, including archaeological sites, historic structures, shipwrecks, and artifacts. - NOAA/DOC

Market Access Program (MAP) - MAP, previously called the Market Promotion Program or MPP, is administered by the Foreign Agricultural Service and uses funds from the Commodity Credit Corporation. It helps producers, exporters, private companies, and other trade organizations finance promotional activities for U.S. agricultural products. MAP is designed to encourage development, maintenance, and expansion of commercial agricultural export markets. Activities financed include consumer promotions, market research, technical assistance, and trade servicing. The Export Incentive Program, which is part of MAP, helps U.S. commercial entities conduct brand promotion activities including advertising, trade shows, in-store demonstrations, and trade seminars. MAP is authorized in Section 244 of the FAIR Act of 1996. The program promotes exports of specific U.S. commodities or products in specific markets. Under MAP, program participants are reimbursed for their expenses in carrying out approved promotional activities. Participating organizations include nonprofit trade associations, state regional trade groups, and private companies. Funding authority is limited to $90 million annually for fiscal years 1996- 2002.

Market Aspects of Property Regimes - From an economic perspective it is convenient to distinguish four main types of property regimes affecting natural resources. State property refers to resources that are managed by the state, either directly or by delegating authority to local bodies. State property may consist of both resources that are owned by the state but that are capable of private ownership, and public resources that cannot be privately owned and that the state must manage in the public interest. The seashore and the territorial waters of most countries fall into the category of public resources and, in some countries, public resources also include freshwater and land. Indeed, it is generally believed that all societies originally treated land in this way. This concept is summed up in the remark of a West African chief that `Land belongs to a vast family of which many are dead, few are living, and countless numbers are still unborn' (cited by Simpson, 1976). The state determines the rules of access to state property and, generally, a controlling agency ensures such access is respected. The state may lease the natural resource to groups or individuals under specified conditions and for a specified period. For example, grazers may have access to state pastureland, or a mining company have the right to mine minerals on state land. Where a long-term lease is granted, the regime might resemble private property. On the other hand, short-term leases provide no incentives to the concessionaire to practice conservation. Where rules of access are not enforced, because of a lack of personnel and finance, logistical problems or corruption, such resources become (factually though not legally) open access regimes. Open access regimes refer to situations where no-one controls access to a resource and anyone can exploit it. No one has rights to the resource but neither does anyone determine or enforce norms for its use. As a result, such resources tend to be used opportunistically and no one manages them since there is no incentive to use them prudently. Thus, open access tends to entail overexploitation D the benefits of a greater harvest accrue to an individual (or group) while the cost (diminishing stocks) will be shared by all. Open access regimes are often the result of institutional failures that undermine former collective or individual regimes. Common property refers to situations where a group of co-owners have exclusive rights of access to a resource for specific or general purposes (e.g. to draw water for irrigation or to use land for cultivation or grazing). Such groups are social units that can vary in nature, size and internal structure. The group determines membership, which usually implies some common cultural norms. Internal authority systems usually apply sets of rules and codes of conduct. Groups vary widely but are typically `social units with definite membership and boundaries, with certain common interests, with at least some interaction among members, with common cultural norms and often their own endogenous authority systems' (Bromley and Cernea, 1989). Tribal groups, sub-village groups, small pastoral groups and kin systems are examples of common property regimes. The group, having a common interest and rules, generally shares resources fairly and manages them sustainably. In the case of commonly owned land, customary tenure systems usually identify leaders who allocate specific areas of land to individuals or families from the group who, in turn, have specific rights and duties in respect of that land and retain it for as long as it is productively used. However, there is a risk of `free riding', individuals being tempted to overexploit their share of the resource while counting on others to observe the rules. Such defections should be treated with strong punitive action. Private (alienable) property includes property owned by individuals or legal entities, where owners can exclude others, transfer ownership and manage and invest knowing that good stewardship will bring in long-term benefits. Private owners will usually have an economic incentive to use their property prudently and sustainably. However this is not always the case and the prospect of obtaining high returns in the short term may cause some private owners (particularly absentee owners, who may be investors with high capital mobility) to exploit resources unsustainably. In practice, private owners are often constrained by legal rules that place restrictions on their freedom to exploit their resources (e.g. legislation governing air or water pollution levels from factories). For any property regime, it is essential that an authority system (e.g. state authority or traditional leaders) can meet the expectations of rights holders. When the authority system breaks down, management of the natural resource fails, and the entire system changes (i.e. common property degenerates into open access). The authority mechanisms and capacity to enforce compliance ensure compliance with, and integrity of, the property regime.

Market-based pollution control - The main alternative to command-and-control style regulations, market-based mechanisms attempt to make pollution or the right to create it a tradable commodity. The United States Environmental Protection Agency has had quite a bit of success in reducing acid rain by requiring companies to purchase sulfur dioxide emissions permits on the open market. Companies then have a continuous incentive to find the cheapest and best way to reduce their SO2 emissions, in many cases going beyond what had previously been required by law and often finding innovative and surprisingly cheap ways of doing it. Other examples include charging households a per bag fee for their trash but not for their recyclables. In this way, families and businesses are encouraged to recycle as much as possible or otherwise reduce the amount of solid waste they generate.

Market Basket - Average quantities of consumables, including U.S. farm foods, purchased per household for a given base period, used to compute an index of retail prices.

Market Economy - See Capitalism.

Market failures - Cases when a market economy fails to provide people with a desirable supply of certain kinds of goods and services. Market failures can occur in a market economy when it does not produce enough public goods and goods with positive externalities, when it produces too many goods with negative externalities, when goods are overpriced by natural monopolies, and when market agents do not have access to sufficient information, such as information about the quality of some consumer goods. These market failures usually justify economic intervention by the government. But there is always the risk of government failure, in which faulty political processes or institutional structures prevent government measures from improving social welfare. A divergence between the market outcome, without intervention, and the economically efficient solution. - WB

Market Instruments - (See economic instruments)

Market liberalization - Removing and abstaining from using state controls that impede the normal functioning of a market economy- for example, lifting price and wage controls and import quotas or lowering taxes and import tariffs. Market liberalization usually does not mean that a government completely abstains from interfering with market processes. - WB

Market Price - The price per bushel (or pound or hundredweight) of an agricultural commodity paid in the private sector. It can sometimes refer to the price paid at domestic seaports or large inland terminal markets (such as daily cash prices listed in newspapers) and sometimes refers to the farm price.

Market Value - Market values of crops are based on market receipts. Receipts are larger on irrigated land because yields are higher or quality is higher or because different crops are grown. For the nation as a whole, crop sales average about $145 per acre from non-irrigated land and about $280 per acre from irrigated land. Net profits average about $25 per acre higher on irrigated farms than on non-irrigated farms. Vegetable, orchard, vineyard and nursery crops are high value crops that return higher profits per acre. [USDA-SCS 1982 NRI]

Market Valuation - 1) Market price valuation applied in national accounts; 2) Value of natural resources and of their depletion and degradation, imputed in environmental accounting and estimated on the basis of expected market returns. (See also discounting [of natural assets] and Hotelling rent) (UN)

Marketing (or Crop) Year - Generally, the 12-month period, from the beginning of a new harvest, over which a crop is marketed. For example, for wool, mohair, and Hawaiian sugarcane, the marketing year is January 1- December 31; for honey, it is April 1-March 31; for wheat, barley, and oats, it is June 1-May 31; for flue- cured tobacco, it is July 1-June 30; for cotton, peanuts, and rice, it is August 1-July 31; for sugar beets, it is September 1-August 31; for corn, sorghum, soybeans, mainland sugarcane, all tobacco but flue-cured, and milk, it is October 1-September 30.

Marketing allotments - When in effect, provide each processor or producer of a specified commodity a specific limit on sales for the year, above which penalties would apply. Sugar allotments, for example, were authorized during 1991-95, but were suspended by the 1996 Act. - USDA-Economic Research Service Farm and Commodity Policy Glossary of Policy Terms

Marketing assessments - A fee or charge per unit of domestic production or sales that producers, processors, or first purchasers must pay to the Government in order to help pay for commodity program costs. - USDA-Economic Research Service Farm and Commodity Policy Glossary of Policy Terms

Marketing loan program - Provisions first authorized by the Food Security Act of 1985 (P.L. 99-198) that allow producers to repay nonrecourse commodity loans at less than the announced loan rate whenever the world price or loan repayment rate for the commodity is less than the loan rate. Prior to 1985, commodity loans had to be repaid at the original loan rate, which often resulted in the accumulation of surplus commodities in Government inventories. Marketing loan provisions are aimed at reducing government costs of stock accumulation. Marketing loan provisions were originally mandated only for rice and upland cotton. The Secretary of Agriculture had the option of implementing marketing loans for wheat, feed grains, soybeans, and honey under the 1985 Act and the subsequent farm acts. The 1996 Act mandates that marketing loan provisions be implemented for feed grains, wheat, rice, upland cotton, and all oilseeds. - USDA-Economic Research Service Farm and Commodity Policy Glossary of Policy Terms

Marketing orders - Federal marketing orders authorize agricultural producers in a designated region to take various actions to promote orderly marketing by influencing such factors as supply and quality, and to pool funds for promotion and research. Marketing orders are initiated by the industry, but must be approved by the Secretary of Agriculture and by a vote among affected producers. Once approved, a marketing order is mandatory for all producers in the marketing order area. There are marketing orders for a number of fruits, nuts, and vegetables, and for milk. - USDA-Economic Research Service Farm and Commodity Policy Glossary of Policy Terms

MAR List (or MAR List of Wetlands) - The List of Wetlands of International Importance. (IUCN) http://www.ramsar.org/lib_legal_e_1.htm 

MARPOL - The International Convention for the Prevention of Pollution from Ships, 1973 (UN)

MAR Project - In 1960, IUCN received and approved a proposal from L. Hoffmann which called for an international programme on the conservation and management of marshes, bogs and other wetlands. It was designated Project MAR since these are the first three letters of the word for wetlands in several languages - MARshes, MARecages, MARismas. IUCN asked that the International Council for Bird Protection (ICBP) as well as IWRB should be asked to participate, and appointed L. Hoffmann as Coordinator. He directed the MAR project in 1958 (IUCN, IWRB, ICBP), which aimed to promote waterbird monitoring and wetland censuses. Its major outcome was the signature of the international Ramsar Convention in 1971 for the conservation of wetlands. At the beginning of 1962 he became the honorary Director of IWRB, which from then onwards played a central role. L. Hoffmann organized a MAR Conference in the French Camargue, at Stes-Maries-de-la-Mer, from 12 to 16 November 1962. This was attended by some 80 experts from 12 European countries and from Australia, Canada, Morocco and the United States. Nearly 60 papers were presented on the economic, scientific and moral considerations; the criteria for defining wetland areas and reserves; the legal and administrative devices; the management, utilization and restoration of wetlands; the role of man-made aquatic habitats; the international efforts needed for the conservation of wetlands and their fauna. The impressive Conference Proceedings appeared in 1964, in English and French. The participants of the conference, well aware that conference proceedings, however seminal, tend to gather dust on library shelves, made 13 recommendations for action. Very appropriately the first was "that IUCN publish an educational leaflet in which the educational, scientific, economic, recreational and other values of wetlands are clearly set forth and further recommends that UNESCO (the United Nations Educational, Scientific and Cultural Organization) or other appropriate international agency be requested to help finance this leaflet for mass circulation in order to present, in unequivocal terms, the values of wetlands to mankind".

Maryland Environmental Trust v. Gaynor, 140 Md. App. 433, 780 A. 2d 1193 (2001), revisedd Maryland Court of Appeals, No. 108, July 19, 2002. EASEMENTS: No wrongful inducement for environmental trust. Failure to state more explicitly that the Maryland Environmental Trust (MET) would accept the conservation easement without a subdivision restriction was not sufficient, by itself, to constitute fraud, as MET had no duty to do so. There was no fiduciary or confidential relationship existing between the property owners and MET that would have required such a disclosure in order to avoid any breach of trust. The letter from MET to the owners truthfully and accurately conveyed the decision made by the Board of Trustees at the meeting and concealed nothing from them, who admitted at trial that MET had never stated to them that the no-sub\-di\-vi\-sion restriction was required. Therefore, as a matter of law, the owners failed to produce proof amounting to clear and convincing evidence that MET committed fraud. Circuit Court for Anne Arundel County Case No. C-1998-44598. Bell, C.J., Eldridge, Raker, Wilner, Cathell, Harrell, Battaglia, JJ. The opinion of the court was delivered by: Raker, J. This case involves a conservation easement [fn 1] upon property donated to petitioner, the Maryland Environmental Trust (MET), pursuant to Maryland Code (1974, 1996 Repl. Vol., 2001 Supp.) 2-118 of the Real Property Article. Respondents Cathy Cook Gaynor and Kevin Gaynor initiated this action in the Circuit Court for Anne Arundel County, claiming that MET unlawfully induced them into granting a conservation easement on their land by not disclosing that MET would have accepted the easement without also requiring them to surrender their right to subdivide their property. We shall hold that respondents failed to produce clear and convincing evidence that MET committed fraud in inducing them to donate the easement at issue in this case. Accordingly, we shall reverse the judgments of the Court of Special Appeals, Environmental Trust v. Gaynor, 140 Md. App. 433, 780 A.2d 1193 (2001), and the Circuit Court rescinding their Deed of Conservation Easement. MET is a public agency governed by a Board of Trustees and operating as part of the Department of Natural Resources. See Maryland Code (1973, 2000 Repl. Vol., 2001 Supp.) 3-202 of the Natural Resources Article. [fn 2] MET was created in 1974 to "conserve, improve, stimulate, and perpetuate the aesthetic, natural, health and welfare, scenic, and cultural qualities of the environment, including, but not limited to land, water, air, wildlife, scenic qualities, open spaces, buildings or any interest therein, and other appurtenances pertaining in any way to the State." 3-201 (a). MET is empowered to "acquire and hold real and personal property, or any interest therein, of aesthetic, scenic, or cultural significance ... by lease, gift, purchase, devise, bequest, or by any other means, and conserve, improve, administer, invest, or dispose of the properties for the purposes of the Trust ..." 3-203 (3). MET's purpose "is of general benefit to the citizens of this State, and is charitable in nature," by protecting property for the benefit of the public at large thereby preserving the natural environment and preventing sprawl development. 3-210 (a). One way that MET accomplishes its purpose is by accepting donated conservation easements. By accepting the easement, the State undertakes to enforce the restriction in perpetuity. In 1989, respondents [fn 3] contacted MET to inquire about donating a conservation easement on their twenty-five acre property. They were informed that MET normally accepts easements on property of fifty acres or larger. Thereafter, respondents contacted several of their neighbors about donating easements simultaneously so that the aggregate acreage of the properties donated would qualify them for conservation easements. Several neighbors expressed interest in donating conservation easements to MET. In June 1989, representatives of MET met with respondents and their neighbors. Negotiations between the parties occurred throughout the summer of 1989. Although respondents and their neighbors explored donating conservation easements simultaneously, individual easements were required for each property, and the terms of each of those easements varied. On September 11, 1989, the properties were presented to MET's Board of Trustees. The minutes of that board meeting state as follows: "The Board voted to accept the easements, subject to the following conditions: (1) The donors proposed dispute resolution language should be modified ... ; (2) The deeds must contain a clause to state that MET may unilaterally make the 501(c) local land trust a co-grantee ... ; (3) Staff should ask for a "no subdivision" provision in the Servary deed, and also in the Gaynor and Schumacher deeds. This is most important for the Servary deed. However, the Board will accept the easements without this provision if necessary..." Respondent Kevin Gaynor testified at trial that he spoke to James Highsaw, MET's designated representative, by telephone on September 12, 1989, that Mr. Highsaw told him about the board meeting, and that he got the impression from the conversation that MET would not accept the easements unless the property owners agreed to the subdivision restriction. He testified that Mr. Highsaw told him that the Board of Trustees "wanted" the restriction and "felt strongly" about it. He assumed that this meant that the Board required the restriction as a condition of accepting the easements. On September 15, 1989, Mr. Highsaw sent a letter to respondent Kevin Gaynor stating as follows: "Dear Kevin: As I discussed with Barbara Parker this week, our Board of Trustees agreed to accept the easement offers on the condition that the proposed dispute resolution language be changed to read discuss the matter for 30 days instead of discuss referring the matter to arbitration. The Board also advised that the deeds should contain a provision stating that MET may unilaterally make the 501(c) local land trust a co-grantee of the easements. I will have to get the exact wording to you after further discussion with a Board member. The Board requests that the owners consider adding a "no subdivision" provision to the Gaynor, Schumacker/Parker, and Servary deeds to ensure that the properties remain intact under one ownership. Because of its smaller size, the Board especially recommends this provision for the Servary property. With such a provision, the second home site on each property could not be subdivided off and sold to a new owner as a separate lot. Please report this to each property owner, and discuss this request at your September 18th meeting and get back to me. I will proceed with asking the Board of Public Works to ratify the easements at their October 4th meeting. In the meantime, I will need your response to the "no subdivision" provision." According to respondents, Mr. Highsaw never stated specifically that MET's Board of Trustees would accept the easements without the subdivision restriction. Mr. Highsaw testified that he had no independent recollection of his telephone conversations with respondents in 1989, but that he drafted the minutes of the September 11, 1989 meeting of MET's Board of Trustees because that was one of his duties as the staff person in attendance. Mr. Highsaw also testified that he believed that he told respondents and the other property owners that MET's Board of Trustees had accepted their easements without the no-subdivision provision and that this information was conveyed in his September 15, 1989 letter. One of the other property owners, Barbara Parker, testified at trial as to her understanding of Mr. Highsaw's September 15, 1989 letter. She testified that it was clear that the request for a subdivision restriction was not a requirement and that she was certain that she informed respondents and the other property owners that she and her husband would not agree to a no-subdivision provision. No such subdivision restriction was included in the conservation easement that the Schumacher/Parker family donated to MET. In December 1997, respondents learned that their neighbors, Dale Schumacher and Barbara Parker, intended to build a second home on part of their property and that their conservation easement to MET did not include a subdivision restriction. On February 11, 2000, respondents filed a First Amended Complaint in the Circuit Court for Anne Arundel County against MET, seeking declaratory judgment for ultra vires action and raising claims of fraud in the inducement, negligent misrepresentation, and deceit, concealment, and nondisclosure. A court trial was held on March 15, 2000 in the Circuit Court for Anne Arundel County. At the close of respondents' case, MET moved for judgment on all counts. The court granted judgment in favor of MET on the claim for declaratory judgment for ultra vires action. In a written memorandum opinion and order, the Circuit Court found in favor of respondents on their claim for fraud and ordered rescission of the Deed of Conservation Easement, as well as all other written and oral agreements between the parties underlying the conservation easement. The Circuit Court entered judgment for MET on the claims for negligent misrepresentation and deceit, concealment, and nondisclosure. MET noted a timely appeal to the Court of Special Appeals, and respondents noted a timely cross-appeal. The intermediate appellate court held that the trial court did not err in finding that MET was fraudulent in its communications with respondents and, as a result of that holding, did not address the issues raised in respondents cross-appeal. Environmental Trust v. Gaynor, 140 Md. App. 433, 780 A.2d 1193 (2001). The majority of the panel held that the "legal conclusion that a false statement was made is supported by the undisputed fact that Mr. Highsaw affirmatively represented to Mr. Gaynor that he would send him an outline of the board's actions." Id. at 442, 780 A.2d at 1198. The court based its conclusion on its finding that Mr. Highsaw's letter to respondents "gave the impression of being a complete overview of the Board's decision when, in fact, it concealed the truth of the Board's actual decision." Id. at 442, 780 A.2d at 1198. The court concluded that the failure to state expressly that the no-subdivision provision was optional had the effect of defrauding respondents. See Id. at 443, 780 A.2d at 1198. Judge Deborah S. Eyler dissented, noting that the letter sent to Mr. Gaynor fully and accurately conveyed the precise decision made by the Board at the meeting. See Id. at 444-45, 780 A.2d at 1199 (Eyler, J., dissenting). Judge Eyler concluded that no fraud had occurred because "[t]here is nothing whatsoever in the language of the letter to suggest that the owners had to agree to the `no subdivision' provision in their deeds, or the easements would not be accepted." Id. at 444, 780 A.2d at 1199. We granted MET's petition for writ of certiorari to determine whether the courts below improperly determined that MET committed fraud in obtaining the conservation easement from respondents "when the State made no misrepresentation to acquire the donation but rather issued a letter that the trier-of-fact in this case found was `ambiguous' with respect to a proposed restriction on the donation." Environmental Trust v. Gaynor, 367 Md. 88, 785 A.2d 1291 (2001). II. In order to recover in a tort action for fraud or deceit, a plaintiff must show, by clear and convincing evidence: "`(1) that the defendant made a false representation to the plaintiff, (2) that its falsity was either known to the defendant or that the representation was made with reckless indifference as to its truth, (3) that the misrepresentation was made for the purpose of defrauding the plaintiff, (4) that the plaintiff relied on the misrepresentation and had the right to rely on it, and (5) that the plaintiff suffered compensable injury resulting from the misrepresentation.'" VF Corp. v. Wrexham Aviation, 350 Md. 693, 703, 715 A.2d 188, 192-93 (1998) (quoting Nails v. S & R, 334 Md. 398, 415, 639 A.2d 660, 668 (1994)). Except in a few special types of transactions not implicated in this case, Maryland recognizes no general duty upon a party to a transaction to disclose facts to the other party. See Feageas v. Sherrill, 218 Md. 472, 476, 147 A.2d 223, 225 (1958). While it is not necessary to produce proof of wrongful conduct in order to succeed in establishing constructive fraud that justifies the rescission of a contract, a plaintiff still must show the "breach of a legal or equitable duty which, irrespective of the moral guilt of the fraud feasor, the law declares fraudulent because of its tendency to deceive others, to violate public or private confidence, or to injure public interests." Ellerin v. Fairfax Savings, 337 Md. 216, 236 n.11, 652 A.2d 1117, 1126 n.11 (1995) (citations omitted). The facts established at trial in this case were legally insufficient to support a finding, by clear and convincing evidence, that MET made to respondents a misleading or false representation of fact constituting fraud. The minutes of the meeting of MET's Board of Trustees reflect that the Board voted to accept respondents' easement subject to two conditions not involved in the present controversy (regarding dispute resolution language and the local land trust) and that the Board intended that its representative seek a no-subdivision provision. Viewed in the light most favorable to respondents, Mr. Gaynor's testimony regarding the communications from MET's representative, Mr. Highsaw, subsequent to the meeting of the MET Board (namely, that he got the impression from Mr. Highsaw's telephone call after the meeting that the subdivision restrictions were mandatory) was not sufficient, as a matter of law, to constitute fraud. This is hardly sufficient evidence of the misleading statement required for a claim of fraudulent inducement, particularly in light of Mr. Gaynor's admission at trial that Mr. Highsaw's words had been to the effect that the Board "wanted" the restriction and "felt strongly" about it. Furthermore, the letter that Mr. Highsaw sent to respondents made clear, by its plain language, that MET was requesting that respondents and the other property owners "consider adding a `no subdivision' provision" to their deeds (emphasis added). Mr. Highsaw's letter specifically employed the verbs "request," "consider," and "recommend" in conveying the Board's position on the subdivision issue. There was nothing whatsoever in the language of the letter to suggest that respondents had to agree to include a subdivision restriction in their deeds as a requirement of MET's acceptance thereof. This is particularly apparent when the language regarding MET's request for a subdivision restriction is viewed along side the contrasting language requiring the other two mandatory provisions. The letter closed by informing respondents that Mr. Highsaw would be asking the Board of Public Works to ratify the easements and that he would need a response to the no-subdivision provision before doing so. Mr. Highsaw's letter did not ask for a response with respect to the proposed dispute resolution and local land trust provisions because those provisions, unlike the subdivision restriction, were mandatory. Failure to state more explicitly that MET would accept the conservation easement without a subdivision restriction was not sufficient, by itself, to constitute fraud, as MET had no duty to do so. There was no fiduciary or confidential relationship existing between respondents and MET that would have required such a disclosure in order to avoid any breach of trust. See Gingell v. Backus, 246 Md. 83, 92, 227 A.2d 349, 353 (1967). The letter from Mr. Highsaw to respondents truthfully and accurately conveyed the decision made by the Board of Trustees at the meeting and concealed nothing from respondents, who admitted at trial that Mr. Highsaw never stated to them that the no-subdivision restriction was required. Therefore, as a matter of law, respondents failed to produce proof amounting to clear and convincing evidence that MET committed fraud. JUDGMENT OF THE COURT OF SPECIAL APPEALS REVERSED.

Mass Balance - This term describes a scientific method for evaluating the sources, transport and fate of contaminants entering a water system, and the effects of those contaminants on water quality. In a mass balance budget the amounts of a contaminant that enters a river or lake--minus the quantity that is buried in sediment or otherwise stored, transformed or broken down -- must equal the amount leaving the system. Once a mass balance budget is determined for a particular pollutant, its long-term effects on water quality can be simulated by mathematical models and that information can be used to set priorities for research and remedial action. - Great Lakes glossary

McIntire-Stennis Act of 1962 - P.L. 87-788 (October 10, 1962) makes funding available to the state agricultural experiment stations and to forestry schools and programs at the land grant colleges of agriculture for forestry research. The research covers such areas as reforestation, woodlands and related watershed management, outdoor recreation, wildlife habitats and wood utilization. Many of the research projects are performed cooperatively with scientists at the laboratories of USDA's Forest Service. USDA distributes McIntire-Stennis funds by a formula that allocates $10,000 to each state, with 40% of the remainder being distributed according to a state's share of the nation's total commercial forest land, 40% according to the value of its timber cut annually, and 20% according to its state appropriation for forestry research.

The Methods and Data Comparability Board (Methods Board) - A partnership of water-quality experts from Federal agencies, States, Tribes, municipalities, industry, and private organizations who all share a commitment to developing water-quality monitoring approaches that facilitate collaboration and comparability among all data-gathering organizations. Both the Methods Board, and its parent organization, the National Water Quality Monitoring Council are co-chaired by USGS and USEPA. The Council and Board are workgroups under the Advisory Committee on Water Information (ACWI), chartered in 1997 to develop a voluntary, integrated, and nationwide water quality monitoring strategy. ACWI member organizations see NEMI as an important element of this strategy. A second tool developed by the Methods Board is a common set of data elements for documenting the content and quality of monitoring data, adopted by ACWI in May 2000. These Water Quality Data Elements , also available on the Web, were also recently adopted by the Environmental Data Standards Council, a USEPA, state, and tribal partnership, and the Environmental Commissioners of the States. "The State regulators who manage the nation's water quality programs are pleased to see the development of this database because we expect it to assist environmental professionals in selecting appropriate analytical methods for water quality investigations," said Robbi Savage, Executive Director of the Association of State and Interstate Water Pollution Control Administrators.

Methyl Bromide - A fumigant used for soil treatment, to control pests in post harvest storage, for killing pests on fruits, vegetables, and grain going into export trade, for plant quarantine treatment, and for fumigation of buildings. Because methyl bromide contributes to depletion of stratospheric ozone, it is subject to phase out requirements of the 1987 Montreal Protocol on Ozone Depleting Substances and Section 602 of the Clean Air Act (CAA). The Montreal Protocol and Vienna Adjustments require a complete phase out in industrialized countries by the year 2010, and a future freeze in developing country use. The Clean Air Act bans U.S. production and import as of January 1, 2001. The produce industry in the United States and abroad are seeking exemptions for some agricultural applications after the phase out dates. U.S. growers have petitioned the EPA to extend the domestic phase out date to be the same as other industrialized countries under the Montreal Protocol. All methyl bromide regulations so far exempt quarantine and pre-shipment treatment of agricultural commodities; however, this exemption is being reevaluated after completion of additional scientific assessments. Methyl bromide is regulated as a pesticide under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as a hazardous substance under the Resource Conservation and Recovery Act (RCRA), and is subject to reporting requirements under the Emergency Planning and Community Right to Know Act (EPCRA).

Missouri v. Holland 252 U.S. 416 (1920) - Many of the concerns shared by the American Bar Association (ABA) and other proponents of what would become the Bricker Amendment can be traced to the obscure and seemingly innocuous case of Missouri v. Holland in 1920. Its rulings on state regulation of the treatment of certain species of migratory birds were ripe with significance for the future conduct of American foreign relations. The dispute dated back to 1913, when Congress passed a measure establishing federal regulations over the killing, capturing, or selling of such birds. At the time, federal courts ruled it a usurpation of rights reserved to the states under the Tenth Amendment. But when President Woodrow Wilson codified these regulations in a 1916 treaty with Great Britain, the Supreme Court upheld them by citing the 'supremacy clause' in the Constitution. The Court concluded that if "the treaty is valid there can be no dispute about the validity of the statute ... as a necessary and proper means to execute the power of the Government." The decision was a fateful one, for it would be cited in several subsequent cases that served to expand the power of the central government. Decades later, in the wake of U.S. ratification of the United Nations Charter, the precedent set in Missouri and subsequently elaborated in United States v. Pink (1942) took on a profound significance. The Charter had been ratified with the explicit assurance that it authorized no UN interference in the domestic concerns of the United States, or of any other member nation. These Court decisions raised difficult questions regarding that portion of American sovereignty that UN membership may have forced the United States to relinquish. One short year after the ratification of the U.N. Charter, the National Lawyers Guild, citing Missouri v. Holland, concluded that lynching fell under federal jurisdiction and hence anti-lynching legislation within federal authority, on the grounds that such legislation would serve to satisfy America's human-rights obligations under the United Nations Charter. In 1948, four Supreme Court justices concurred in the case of Oyama v. California, citing the UN Charter as a rationale for the abolition of a California law that restricted land ownership among aliens ineligible for citizenship, since in practice it applied only to Japanese aliens. The case of Sei Fujii v. California had a like outcome in 1950. - See The Bricker Amendment

Miticide - Pesticide used for killing mites on animals or humans. (UN)

Mitigating Measures - Modifications of actions which (a) avoid impacts by not taking a certain action or parts of an action; (b) minimize impacts by limiting the degree or magnitude of the action and its implementation; (c) rectify impacts by repairing, rehabilitating or restoring the affected environment; (d) reduce or eliminate impacts over time by preservation and maintenance operations during the life of the action; or (e) compensate for impacts by replacing or providing substitute resources or environments. (BLM)

Mitigation - Actions taken to avoid, minimize, reduce, eliminate, replace, or rectify the impacts of a land management practice.

Mitigation - 1.) "Mitigations" are theoretically offsets to the impact of a project required of a developer by government. These are commonly imposed in connection with wetlands infringements and often require the creation of new wetlands equal to a multiple of the acreage that is to be disturbed. Another way that government agencies impose mitigations is to require the purchase of land from a land trust followed by its donation by the developer to government. Monetary or land donations to non-profits may be required as enforcement or project "mitigations." Or unrelated wildlife habitat set-asides may be required as mitigations for wetlands infringements. Infinite variations of these themes are possible. These conditions are related to the variance (see). "Mitigations" and exactions (see) are closely related and often indistinguishable. See Nexus, Proportionality - Zoning (Case Law) Glossary 2.) Restoring, replacing, or creating ecological habitats (usu. wetlands) in one area to compensate for loss of natural habitats in another area due to development. Syn: compensatory restoration 3.) Avoiding, minimizing, or reducing ecosystem losses. - NPS Ecology and Restoration Glossary 4. Steps taken to avoid or minimize negative environmental impacts. Mitigation can include: avoiding the impact by not taking a certain action; minimizing impacts by limiting the degree or magnitude of the action; rectifying the impact by repairing or restoring the affected environment; reducing the impact by protective steps required with the action; and compensating for the impact by replacing or providing substitute resources. - Bioenergy Glossary

Mobile Home - A domicile transportable in one or more sections, designed and equipped to contain not more than two dwelling units, to be used with or without a permanent foundation system.

Mobile Population - It is virtually impossible to fully quantify the demographic characteristics of this group. A main part of their survival strategy is to remain unknown, hidden, mobile, and elusive. In more than one way ours is an uprooted generation. For many throughout the world the old roots of life, home, family, country, tradition, custom, even religion and language have been either destroyed or transplanted. Since World War II vast sections of humanity have been shifting about from one place to another, migrants in a mobile population explosion. The dual problem of migrant-immigrant requires attention and action from many sides-Church, state, sociological analysis, welfare groups, and the United Nations. Perceived differences between nations in welfare for citizens are a main factor contributing to migration. Overpopulation, high unemployment rates, ecological disasters, deprivation of civil rights, political prosecutions, and low standards of living, all of these lead some to seek a better life elsewhere. These threats to welfare make for a mobile population and create new opportunities for criminal organizations. Farm worker families are by definition a mobile population that follows agricultural employment opportunities along a seasonal migrant stream that takes them from one state to another throughout the year. Any public health insurance program that is administered solely by the States does not fit the needs of this vulnerable population. The "MediKids" program would solve this problem for migrant and seasonal farm worker children and other similarly mobile populations by creating a fully portable Federally administered health insurance program for low-income and uninsured families.

The Monongahela decision (caused the National Forest Management Act of 1976) - In the Monongahela Decision (Izaak Walton League v. Butz, 1975), it was found that some common Forest Service management practices were illegal, and citizens had lost confidence in the stewardship capabilities of the Forest Service. There were arguments that the discretion of the Forest Service should be severely limited and a prescriptive management regime imposed by Congress.

Monsoon - A seasonal, large-scale reversal of winds in the tropics, chiefly occurring as a result of differential heating of the oceans. It exerts greatest effect in India, China and Southeast Asia. The term is derived from the Arabic word 'mawsim' and is commonly used to describe the intense rainfall that generally accompanies the wind reversal. Monsoons bring rain during the summer as they blow inland from the sea. The rest of the year is dry with the winds blowing in the opposite direction. (UNESCO)

Montreal Protocol (on Ozone Depleting Substances) - An 1987 international agreement, to which the United States is a signatory, reached in Canada to review the role of chlorofluorocarbon (CFC) gases in the destruction of the ozone layer. The Protocol was signed by 30 governments, together with the European Community (EC), although some CFC-producing Third World countries, notably China and India, withheld their agreement until assurances on compensation or technology-transfer for production of alternatives were agreed. The agreement aimed to freeze CFC production at 1986 levels. It also called for consumption to be reduced gradually to 50% of 1986 levels by 1999. Two other key ozone-depleting chemicals, carbon tetrachloride and methyl chloroform, were added to the Protocol during subsequent meetings. (UNESCO)

The Montreal Process - Following UNCED, in September 1993, the Conference on Security and Cooperation in Europe sponsored an international seminar in Montreal, Canada on Sustainable Development of Boreal and Temperate Forests. This conference provided the conceptual basis for subsequent regional and international initiatives to develop criteria and indicators for sustainable forest management. In June 1994, the Working Group on Criteria and Indicators for the Conservation and Sustainable Management of Temperate and Boreal Forests was formed to advance the development of internationally agreed criteria and indicators through a series of meetings hosted by participating countries. This Working Group is now known as the Montreal Process. The Montreal Process Working Group includes Argentina, Australia, Canada, Chile, China, Japan, Republic of Korea, Mexico, New Zealand, Russian Federation, United States of America and Uruguay. These countries cover five continents and together represent 90 percent of the world's temperate and boreal forests (as well as areas of tropical forests) and 60 percent of all forests. They also account for 45 percent of world trade in wood and wood products and 35 percent of the world's population. The Working Group is supported by a Liaison Office hosted by Canada in Ottawa. The seven criteria of the Montreal Process, which are defined by their respective indicators, are viewed as essential components of the sustainable management of forest ecosystems. Six of the criteria and indicators relate to forest conditions, attributes, functions or benefits. Criterion 7 relates to the overall policy framework that can facilitate sustainable forest management and support efforts to conserve, maintain or enhance the conditions, attributes and benefits captured in Criteria 1-6. Taken together, the Montreal Process criteria and indicators provide a common understanding and implicit definition of what is meant by sustainable forest management. They are tools for assessing national trends in forest conditions and management and provide a common framework for describing, monitoring and evaluating progress toward sustainability at the country level. They are not performance standards and are not intended to assess directly sustainability at the forest management unit level. Application of the criteria and indicators will help provide an international reference for policy-makers in the formulation of national policies, improve the quality of information available to decision-makers and the public, and better inform the forest policy debate at national and international levels. Since endorsing the Santiago Declaration, the Montreal Process countries have initiated steps to apply the agreed criteria and indicators based on national circumstances. Working Group meetings have been hosted by New Zealand (Auckland, November 1995) and Australia (Canberra, June 1996) to clarify implementation issues and facilitate initial efforts. The first step was an initial survey by the Liaison Office to determine the current availability of data for indicators in each country and the capacity of countries to report on indicators. Interim survey results indicate that while data availability and reporting capacity varies greatly among the 12 countries, most countries have data for and can report on 50 percent or more of the 67 indicators. The Liaison Office survey also indicates that while resolution of some of the data gaps and reporting problems would involve new research and monitoring systems and new reporting methods, others could be resolved by better defining terms and elaborating measurement approaches. The variations in data availability and reporting capacity found by the survey highlights the wide differences among the Montreal Process countries in terms of forest quality and quantity, land ownership, population, system and structure of government, and economic development. These differences pose special challenges in each country on how to apply the criteria and indicators. They also point to one of the great strengths of the Montreal Process, which is the diversity of the countries involved. Based on the results of the Liaison Office survey, the Montreal Process countries have agreed on a course of action for the future. The Working Group has established an ad hoc Technical Advisory Committee (TAC) to provide advice to the Group on technical and scientific issues arising in connection with implementing the criteria and indicators. The TAC met for the first time in September 1996 in Pasadena, California to develop recommendations on definitions for key terms used in the Montreal Process and approaches to gathering data on various indicators. The Montreal Process Working Group has also prepared an approximation report on the results of initial country efforts to measure the criteria and indicators. Participation in meetings of the Montreal Process includes other countries, international organizations, environmental non-governmental organizations, industry groups and other interested groups, as well as representatives of other initiatives on criteria and indicators.

Monuments - Monuments are tangible landmarks indicating boundaries. (1) Physical Monuments: A physical monument is an existing feature such as a stone, stake, tree, hill, ocean, river or lake, but not the line of an adjoiner. (2) Natural Monuments: A natural monument is a naturally occurring object such as a lake, river, tree, boulder or hill. Although the courts sometimes refer to a record monument as a type of natural monument, such a broad meaning is excluded in this definition. (3) Artificial Monument: An artificial monument is a man-made object such as a stake, fence, set-stone, etc. (4) Record Monument: An adjoiner property called for in a deed such as a street or particular parcel of land. Frequently the boundary line of the adjoiner is referred to as the record monument; actually the entire property, rather than the line, is the monument. Physical monuments may or may not mark a record monument. (5) Legal Monument: Any monument controlling in a legal description. It is often limited in meaning so as to be synonymous with record monument. - Cadastral Data glossary 2. Monuments are referred to as part of the definition of cultural heritage in Article 1 of the Convention (UNESCO 1972). See Cultural heritage - Glossary of World Heritage Terms

Monument (surveying) - A physical structure erected for the purpose of marking points on the earth's surface. The monuments of land surveys range from the deposit of some durable material, a marked wooden stake or post, a marked stone, an iron post having an inscribed cap, a marked tablet set in solid rock or concrete block, a marked tree, a rock in place marked with a cross (X) at the exact point of the corner, and other special types of markers. - Cadastral Data glossary

Mookini v. United States, 303 U.S. 201 (1938) - Balzac v. Porto Rico, 258 U.S. 298 (1921) and Mookini v. United States, 303 U.S. 201 (1938) made it clear that a "district court of the United States" described a court created under Article III and a "United States district court" described a territorial court. The former identified a constitutional court of the United States exercising the judicial power of the United States and the latter merely identified a court for a district of the government of the United States.

Moot or Mootness - Because Federal Courts only have Constitutional authority to resolve actual disputes (see Case or Controversy) legal actions cannot be brought or continued after the matter at issue has been resolved, leaving no live dispute for a court to resolve. In such a case, the matter is said to be "moot". For Supreme Court decisions focusing on mootness, see, e.g., Arizonans for Official English v. Arizona, No. 95-974 (March 3, 1997) and Hicklin v. Orbeck, 437 U.S. 518 (1978). - Supreme Court glossary

Moral Code - The set of rules, values, conventions a person chooses to live by, particularly with respect to their relationships with other humans they know as well as the rest of the human population. A moral code can be extended to include the way one determines to relate to non-human species. (UNESCO)

Moral Rights - Rights that are based on general principles of fairness and justice; they are often but not always based on religious beliefs. People sometimes feel they have a moral right even when they do not have a legal right. For example, during the civil rights movement in the USA, protesters demonstrated against laws forbidding Blacks and Whites to attend the same schools on grounds that these laws violated their moral rights. - United Nations Charter / Human Rights Glossary

Morbidity - Rate of disease incidence; an important measure in epidemiological studies.

More or Less - The words "more or less" in their ordinary use are to be taken as words of caution, denoting some uncertainty in the mind of one using them and a desire not to misrepresent. When used in connection with quantity and distance, "more or less" are words of safety and precaution, intended merely to cover some slight or unimportant inaccuracy. When "125 feet more or less to the point of beginning" is the point of beginning" is the controlling term. "About 12 acres more or less" is indefinite and should be avoided since the word "about" is very broad in meaning. - Cadastral Data glossary

MORPC - Mid Ohio Regional Planning Commission

Morphology - Term used to describe form and structure. - Smart Growth Green Development Glossary

The Morrill Act of 1862 - Gave every State 12,000 hectares of public land for every member of its congressional delegation. The States were to sell the land, and use the proceeds to develop colleges of engineering, agriculture and military sciences.

Morrill Act of 1862 - Enacted July 2, 1862 (chapter 130, 12 Stat. 503), this law allocated federal land to each state and directed the states to sell the land and use the proceeds to establish a college dedicated to the agricultural and mechanical arts. States without federal lands within their borders received land in scrip, giving them the right to sell federal land located in other states. The act resulted in the establishment of the land grant colleges of agriculture. The purpose of the Act was not only to improve the economic and social welfare of farmers, but also to make a higher education with a practical application generally available to all segments of U.S. society. The Act pertained only to the original establishment of the colleges of agriculture, and is not an authority under which the colleges currently receive federal funds.

Morrill Act of 1890 - Enacted August 30, 1890, (chapter 841, 26 Stat. 417), this law authorized additional direct appropriations for the land grant colleges of agriculture that had been established under the Morrill Act of 1862. The most significant feature of the second Morrill Act was that the 1862 schools could receive the additional funds only if they admitted blacks into their programs or if they provided separate but equal agricultural higher education to black students. In the period following the Civil War, sixteen southern states established separate land grant colleges of agriculture for black students under this Act; Congress designated Tuskegee University an 1890 institution at a later date. Federal funds for research and extension at the 1890 schools are provided under subsequent acts, not the second Morrill Act.

Mortality - Trees that were merchantable and have died within a specified period of time of natural causes. The term mortality can also refer to the rate of death of a species in a given population or community.

Most-Favored-Nation Treatment/Status (MFN) - A commitment that a country will extend to another country the lowest tariff rates it applies to any third country. MFN is a basic principle of the General Agreement on Tariffs and Trade (GATT) (1947). Almost all countries are effectively accorded permanent MFN status by the United States. However, Title IV of the Trade Act of 1974 established conditions on U.S. MFN tariff treatment to certain non-market economies, one of which is certain freedom-of-emigration requirements (better known as the Jackson-Vanik amendment). The Act authorizes the President to waive a country's full compliance with Jackson-Vanik under specified conditions, and this must be renewed by June 3 of each year. Once the President does so, the waiver is automatic unless Congress passes (and sustains a Presidential veto of) a disapproval resolution. MFN status for China, which had been originally suspended in 1951, was restored in 1980 and has been continued in effect through subsequent annual presidential extensions. Since the Tiannamen Square incident in 1989, however, the annual renewal of China's MFN status has been a source of considerable debate in the Congress. Several Members have sought through legislation to terminate China's MFN status or to impose additional conditions relating to improvements in China's actions on various trade and non-trade issues. Agricultural interests generally have opposed attempts to block MFN renewal for Congress, contending that several billion dollars annually in current and future U.S. agricultural exports to China could be jeopardized if that country retaliated.
