Vail Agenda - The National Park Service has a ... dedicated work force, some of the nation's most treasured resources under its management, and widespread support from the American public. At the same time, however, it suffers from declining morale, an increasingly diffuse set of park units and programs that it is mandated to manage, serious fiscal constraints, and personnel and organizational structures that often impede its performance. To address these and related issues of critical importance to the national park system, the Service initiated an intensive review of its responsibilities and prospects. This process was undertaken in cooperation with other leading institutions concerned with management of the national park system. The central focus of the process was the 75th Anniversary Symposium 'Our National Parks: Challenges and Strategies for the 21st Century,' which was held in Vail, Colorado in October 1991. This event brought together nearly 700 experts and interested parties from inside and outside the Service to consider the future of the national park system. An "Alliance for Sustainable Practices" came from the Vail conference: http://www.nps.gov/renew/alliance.htm http://www.nps.gov/training/facilitators/endnotes.htm A quote from a speaker at the Vail Agenda: The Vail conference was intended to turn the boat around. Entitled "Our National Parks -- Challenges and Strategies for the 21st Century," it discussed recommendations from "working groups" that had been commissioned by the Park Service and supervised by Harvard's Kennedy School of Government. Conveying the authority and prestige of America's oldest university, it was intended to have maximum public impact. ... confusions about natural preservation are the product of a decision-making process in which public debate seldom occurs and is sometimes suppressed. (The NPCA -- National Parks and Conservation Association -- for example, did not publish a minority report written by several members of the Blue Ribbon Panel who were unhappy with that committee's conclusions.) ... The fits and starts of [National] Park Service policy and the intellectually pathetic attempts to justify it reveal that while everyone wants preservation, no one know what it means. Many biologists, for example, would say that preservation is the promotion of biodiversity; this is the goal of The Nature Conservancy and the United Nations Biosphere Reserve Programme. But even this concept is far from clear. It can refer to the number of species, to the abundance of each species, or to some combination of these two measurements. Estimates of ecological health depend on which standard is chosen, and no one is necessarily more "correct" than another. Thanks to invasions of exotic plants such as Kentucky bluegrass and musk thistle, for example, Yellowstone National Park probably has more species than it had 200 years ago. But the numbers of many of the original species -- such as beaver, bighorn sheep, and white-tailed deer -- have plummeted. Most people would say that the park is therefore worse off, even though one kind of biodiversity has actually increased. So choosing a criterion of biodiversity is a matter of deciding what characteristics we desire a particular ecosystem to exhibit. Preservation, like beauty, is in the eyes of the beholder. ... the Vail conference was disappointing. The public needed to be there. But principal speakers and panel moderators were either cabinet members who know nothing about parks issues (such as the keynoter, Education Secretary Lamar Alexander) or the same old tired group of NPCA insiders. Within the context of these political forces, it is not surprising that preservation policy remains in disarray. It is almost never discussed and indeed was not included on the Vail agenda. Yet until the circle of debate is widened, no amount of tinkering with the structure and budget of the National Park Service will save the national parks. - Alston Chase, from "Unhappy Birthday," (referring to the National Park Service's 75th birthday party held in Vail, Colorado, December 1991) Eco-Watch, 2-19-2002
Valid Existing Rights - Locatable mineral development rights that existed when the Federal Land Policy and Management Act (FLPMA) was enacted on October 21, 1976. Some areas are segregated from entry and location under the Mining Law to protect certain values or allow certain uses. Mining claims that existed as of the effective date of the segregation may still be valid if they can meet the test of discovery of a valuable mineral required under the Mining Law. Determining the validity of mining claims located in segregated lands requires BLM to conduct a validity examination and is called a "valid existing rights" determination. - BLM Surface Mgmt. Regs.
Validity Period - Refers to the time period that any document, classification, etc. could be applicable or used. In classification, usually there is an overlapping time period where the old classification could still be used before being superseded by the revised edition. (UN)

Value-Added Products - In general, products that have increased in value because of processing; such products include wheat flour, and soybean oil. Livestock are considered value-added products because they have increased the value of pasture and feed grains going into them. The terms value-added and high-value are often used synonymously.
Value-Based Pricing - Packers are increasingly using this method of determining how much to pay cattle and hog producers for animals. Rather than simply paying a fixed rate based on the weight of the animals, value-based pricing attempts to establish the individual merits of each animal (or lot) purchased, building quality characteristics such as yield, fat thickness, likely grade (such as choice, select, etc.) into a formula to arrive at the price that will be paid. Under this system, the producer assumes the financial responsibility that the animals, once slaughtered, will meet these criteria. In traditional pricing methods, it is the packer that bears the greater financial risks associated with the uncertain quality of the animals purchased.

Vertical Mulching - A high priority recovery need for the federally-listed desert tortoise and other sensitive species occurring within the California Desert is the restoration of unauthorized routes, or road reclamation (refer to West Mojave Route Designation, Ord Mountain Pilot Unit, Biological Resource Screening Components; Bureau of Land Management 1997). Such restoration allows for the protection of large contiguous blocks of habitat that are relatively unencumbered by vehicle use impacts and related activities. Restoring unauthorized routes would significantly reduce identified habitat fragmentation occurring within designated tortoise critical habitat units and yield tremendous positive benefits affecting recovery of this species. Of the 22 major threats to the tortoise identified in recent research, ten would be significantly reduced by restoring unauthorized roads and trails, including the following: fire, off highway vehicle recreation, animal collection, garbage and litter, handling and manipulation, invasive weeds, noise, vandalism, predation (by ravens and similar subsidized predators), and non off-highway vehicle recreation. The Barstow Field Office of the Bureau of Land Management is currently seeking support among potential cooperators to use "desert tortoise habitat compensation" funds for road and trail restoration. Such funds are occasionally generated, pursuant to guidelines in BLM's Desert Tortoise Rangewide Plan, when habitat-impacting projects are approved within the range of the tortoise that cannot be fully mitigated on-site. In the past, these "habitat compensation" funds have typically been used to acquire private inholdings within designated tortoise critical habitat units. Recently, however, the Barstow Field Office determined that compensation funds generated by several large-scale projects would enable cooperating agencies to protect/enhance a much larger amount of tortoise habitat if these funds were used for route restoration, rather than habitat acquisition. Both methods of offsite habitat compensation are necessary for long-term recovery of the desert tortoise and other sensitive species in certain critical habitat units, and these options should be carefully evaluated on a case-by-case basis. To accomplish both tortoise habitat restoration and route designation objectives in critical habitat units, BLM staff have developed a reclamation strategy commonly referred to as "vertical mulching." This technique involves the placement of structure (live vegetation, rocks, dead shrubs and "snags," bunch-grasses, and various woody material) within the confines of the closed roadway surface, both on the ground surface and in a vertical manner, designed to conform with adjacent vegetation and terrain. Use of this technique is further described below. Discussion: Lessons learned by BLM over past decades have shown that route designation cannot be effectively implemented by simply installing red carsonite "closed to vehicle use" signs on or adjacent to unauthorized routes of travel. Efforts must include encouraging vehicle travel on designated open routes, and making designated closed routes literally disappear into the landscape. To begin this "disappearing act," decompaction and mulching techniques must be applied to closed routes, extending at least to the visual horizon, especially where the closed routes intersect with other routes. The Barstow Field Office has demonstrated that unauthorized roads and trails can be economically restored through use of vertical mulching techniques. These techniques involve placement of boulders and organic structure, such as live/dead and down vegetation, within the disturbed soil portion of affected roadbeds. Only vegetation, rock and woody structure native to the immediate closed route vicinities are used. The estimated cost for restoring tortoise habitat using this technique is $500 per acre, using current technology. The target restoration areas consist of roads and trails that facilitate a variety of anthropogenic impacts to designated desert tortoise critical habitat. The specified collection and installation of mulching material occurs under the supervision of a qualified natural resource specialist, archeologist, biologist or technician, to ensure a minimization of impacts to biological or cultural resources. Areas adjacent to where route closure/rehabilitation is planned may occasionally be used to gather dead vertical mulching material, in a manner designed to avoid causing local dead and down habitat loss, yet also accomplish restoration objectives. In no circumstances are shrubs that shade animal burrows or that are located adjacent to cultural resources, removed for use as mulching material. However, live and dead vegetation from the immediate region, salvaged from land clearing or road maintenance operations, may occasionally be used as mulching material in such restoration projects. Memorandums of understanding developed between land management agencies and local transportation departments, regarding salvage and storage of native material for this application, can facilitate large-scale projects. The use of pitting, ripping, or other scarification techniques within the confines of route or roadbed soil disturbance is sometimes necessary for rapid site recovery. Such scarification is done with hand-tools or through the use of heavy equipment and machinery (toothed rake, pitter, or similar device pulled by a tractor). After scarification, the live or dead vegetation is placed in a vertical fashion within the confines of route or roadbed soil disturbance, in a manner designed to conform to adjacent terrain and vegetation. The Barstow Field Office is able to restore Mojave Desert habitats for about $500 per acre, due to relationships and agreements it has in place with the California Conservation Corps and other local young adult labor groups. Under an existing agreement, the California Conservation Corps will match BLM contributed project funds on a dollar for dollar basis. As a consequence, funds generated by large habitat-disturbing projects could also qualify for matching by the state of California, in the form of matching labor funds available via the use of the California Conservation Corps. Conclusion: Vertical mulching can be an economical technique for restoring unauthorized roads and trails in desert tortoise and other sensitive species' habitats. In some circumstances it may provide much more "bang for the buck" when compared to traditional forms of offsite compensation. Its application in selected areas of the California Desert will reduce anthropogenic impacts to the listed desert tortoise, contributing significantly to the recovery of this threatened species.

Vertically-propagating waves - These are hydrostatic waves that tilt upstream with height. They typically produce wave clouds in the upper troposphere that have a distinct, often laminar appearing, leading edge over or (more typically) downstream of the crest of the mountain range. These clouds may extend over 100km downstream. Clouds produced by these waves tend to be based near or above 500mb, and are favored by conditions of uniform or decreasing static stability in the troposphere, and a cross mountain wind component that does not increase very rapidly with height. The hydrostatic nature of these waves derives from their large horizontal scale; they are favored by broad mountain ranges. These are landmark identifiers. - NOAA-NWS-WMO

Village of Euclid [Ohio] v. Ambler Realty Co., also known as 'The Euclid Decision' (November 22, 1926) - Euclid was about maintaining property values by controlling nuisances. The exclusionary nature of zoning was appropriate and in the public interest as a means to reduce nuisances, and as such overrode the interests of individual property owners. This case, almost by itself, guaranteed zoning as a use of the state's police power, and led to its importance as the most significant tool of land use, and of planning, yet devised. And it was popular not because of its sophistication, but because of its simplicity. The 1926 Supreme Court case upheld that land use could be controlled, and that "nuisance" uses could be kept out of designated areas. The question became, What determines a nuisance use? Later cases determined that zoning could be used to control minimum lot sizes (Simon v. Town of Needham) and minimum floor sizes (Dundee Realty Co. v. City of Omaha), both illustrating that zoning was being used to prop up property valuations. The Supreme Court rationale: The Court will not invalidate the decision by the Euclid Village Council to adopt an ordinance that on its face, as opposed to as applied, is arguably rationally related to the health and safety of the community.
