The Random Forests multiple-regression tree was used to model climate profiles of 25 biotic communities of the western United States and nine of their constituent species. Analyses of the communities were based on a gridded sample of ca. 140,000 points, while those for the species used presence-absence data from ca. 120,000 locations. Independent variables included 35 simple expressions of temperature and precipitation and their interactions. Classification errors for community models averaged 19%, but the errors were reduced by half when adjusted for misalignment between geographic data sets. Errors of omission for species-specific models approached 0, while errors of commission were less than 9%. Mapped climate...

MAPSS (Mapped Atmosphere-Plant-Soil System) is a static biogeography model that projects potential vegetation distribution and hydrological flows on a grid. It simulates type of vegetation and density for all upland vegetation from deserts to wet forests. It uses long term, average monthly climate data (mean monthly temperature, vapor pressure, wind speed, and precipitation) as well as soils information (texture, depth). MAPSS has been used widely for various climate change assessments including the 2000 National Assessment Synthesis Team's report. MAPSS assumes that vegetation distribution is constrained either by the availability of water or of energy for growth. In temperate latitudes, water is the primary constraint...

The REA estimates the condition of 14.2 million acres of land in southern New Mexico. It is based on states described in “ecological site descriptions” (ESDs) and expert knowledge. ESDs have been developed by the Natural Resource Conservation Service, and they are a consistent, science and expert-based resource increasingly used by land managers. It focuses on public rangelands - grasslands, shrublands, and savannas - managed by the Bureau of Land Management, and includes some other lands as well. The REA compares current condition to the expected or “reference” condition, and summarizes the vegetation, ecological processes and restorative management options of these states. Depending on these management options...

RESUMEN En México y EUA, los pastizales del Desierto Chihuahuense han experimentado un gran deterioro desde mediados de 1800's. Ello se ha debido principalmente deficientes prácticas ganaderas, al cambio climático, la supresión del fuego, a la fragmentación de hábitat y cambio de uso de suelo. En conjunto, se ha provocado un incremento en los escurrimientos y la erosión, una disminución de la diversidad biológica y pérdida en las concentraciones de aves, incremento en la invasión de especies no nativas y una disminución en la cantidad de forraje para animales domésticos y silvestres. La Estrategia para la Conservación de los Pastizales de Desierto Chihuahuense (ECOPAD) ofrece un esquema de cooperación para enfrentar...

Many amenity-rich regions are experiencing rapid land-use change in the form of low-density residential development. This widespread land-use change, exurbanization, has profound implications for regional biological diversity and ecosystem function. In the United States, exurban land use occupies seven times more area than land with urban and suburban densities, and has increased at a rate of about 10 to 15% per year. Drivers of exurbanization include technological advancements and increases in tele-commuting, transportation and road-network improvements, and various push- (crime, crowding, poor education systems, etc.) and pull- (affordable or desirable housing, privacy, better schools, etc.) factors. The rapid...

Several statistical compilations of mining claim activity on Federal land derived from the Bureau of Land Management's LR2000 database have previously been published by the U.S Geological Survey (USGS). The work in the 1990s did not include Arkansas or Florida. None of the previous reports included Alaska because it is stored in a separate database (Alaska Land Information System) and is in a different format. This report includes data for all states for which there are Federal mining claim records, beginning in 1976 and continuing to 2010, except Alaska, which only had data to 2007. The statistics compiled from the databases are counts of the number of active mining claims in a section of land each year from 1976...

Sky Island grasslands of central and southern Arizona, southern New Mexico and northern Mexico form the “grassland seas” that surround small forested mountain ranges in the borderlands. Their unique biogeographical setting and the ecological gradients associated with “Sky Island mountains” add tremendous floral and faunal diversity to these grasslands and the region as a whole. Sky Island grasslands have undergone dramatic vegetation changes over the last 130 years including encroachment by shrubs, loss of perennial grass cover and spread of non-native species. Changes in grassland composition and structure have not occurred uniformly across the region and they are dynamic and ongoing. In 2009, The National Fish...

BLM’s Resource Management Plans (RMPs) form the basis for every action and approved use on the public lands. The BLM prepares RMPs for areas of public lands, called planning areas, which tend to have similar resource characteristics. Planning emphasizes a collaborative environment in which local, state, and tribal governments, the public, user groups, and industry work with the BLM to identify appropriate multiple uses of the public lands. Plans are periodically revised as changing conditions and resource demands require. RMPs are used by managers and the public to accomplish the following: Allocate resources and determine appropriate multiple uses for the public lands; Develop a strategy to manage and protect...
