This digital range map represents the range of Colorado pinyon pine (Pinus edulis) in western North America. Data from multiple sources, including existing digitized maps, tabular data, personal communications, USDA Forest Service Inventory and Analysis data, and figures from other publications, were synthesized to create a single digital distribution. The distribution was peer reviewed and iteratively revised based on personal observations of regional authorities.
Climate and land-use change are major components of global environmental change with feedbacks between these components. The consequences of these interactions show that land use may exacerbate or alleviate climate change effects. Based on these findings it is important to use land-use scenarios that are consistent with the specific assumptions underlying climate-change scenarios. The Integrated Climate and Land-Use Scenarios (ICLUS) project developed land-use outputs that are based on a downscaled version of the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) social, economic, and demographic storylines. ICLUS outputs are derived from a pair of models. A demographic...
This soil mapping application displays interactive national maps of soil series extents based on the land area of mapped soils. The information presented has been created from a snapshot of data extracted from the Soil Data Mart and Soil Classification File Database. Due to the update interval and certain assumptions made when assembling the data, these maps are suited for general information exploration and not intended for site-specific investigations. Questions concerning detailed local soil resources should be directed to your local Natural Resources Conservation Service.
Statewide migration barriers for Moose. The severity of the threat to the migration route and the severity of problem noted.
This map layer is a grid map of 2001 average vegetation growth for Alaska and the conterminous United States. The nominal spatial resolution is 1 kilometer and the map layer is based on 1-kilometer AVHRR data. The data were compiled by staff at the USGS Center for Earth Resources Observation and Science.
This map layer shows Omernik's Level III ecoregions, derived from a 1:7,500,000 map created by J.M. Omernik in 1987 and from refinements of Omernik's framework that were made for other projects. Ecoregions describe areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. Omernik's ecoregions are based on the premise that a hierarchy of ecological regions can be identified through the analysis of the patterns and the composition of both living and nonliving phenomena, such as geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology, that affect or reflect differences in ecosystem quality and integrity. All the characteristics are considered...
This map layer is a grid map of 1996 average vegetation growth for Alaska and the conterminous United States. The nominal spatial resolution is 1 kilometer and the map layer is based on 1-kilometer AVHRR data. The data were compiled by staff at the USGS Center for Earth Resources Observation and Science.
This dataset represents soils of Wyoming at 1:100,000- scale. The layer contains 350 separate soils descriptions across 23 Wyoming counties. The layer was compiled based on the five-factor soil forming model using digital surficial geology, bedrock geology, and elevation. This dataset will be more fully documented in 23 AES publications scheduled for completion in winter of 99/00. These publications will use the designation AES Bulletin B-1071 followed by a two letter abreviation for each county.
This theme is polygon data that depicts two types of development for the state of Wyoming. The first is existing development and the second are habitats where there is a high likelihood that development will occur in the near future. We considered development of oil, gas and coal bed methane, mining of minerals (trona, uranimum, coal, and bentonite), urban expansion. Other infrastructure activities such as roads, highways, fiberoptic lines, processing plants, pipelines, other facilities, and various combinations of development that were believed to impact sage-grouse were recorded. Information sources and assessment processes varied depending on data available and resource specialist participation for areas within...

Map of Whooping Crane stopover site use intensity within the Great Plains from satellite telemetered birds, 2010-2014
Whooping cranes (Grus americana) of the Aransas-Wood Buffalo population migrate twice each year through the Great Plains in North America. Recovery activities for this endangered species include providing adequate places to stop and rest during migration, which are generally referred to as stopover sites. To assist in recovery efforts, initial estimates of stopover site use intensity are presented, which provide opportunity to identify areas across the migration range used more intensively by whooping cranes. We used location data acquired from 58 unique individuals fitted with platform transmitting terminals that collected global position system locations. Radio-tagged birds provided 2,158 stopover sites over 10...

This dataset displays the boundaries of Intact Forest Landscapes for the Kenai region of the state of Alaska. Intact Forest Landscapes are defined as areas at least 50,000 hectares that are absent of human disturbance visible on satellite imagery (e.g., roads, logging, mining, settlement). For more information, see the full report, available on the Global Forest Watch website (www.globalforestwatch.org), or the Conservation Biology Institute website (http://www.consbio.org/cbi/projects/show.php?page=alaska);.
This data set represents public land grazing areas (allotments) broken down to the pasture level as administered by the Bureau of Land Management, Worland Field Office, Wyoming.
Species range maps for Wyoming developed by the Wyoming Natural Diversity Database.
Note: The data were created by dissolving on the HERDUNIT attribute of the ant10hh data. This data set represents the 2010 antelope huntarea and herdunit boundaries for Wyoming. It was digitized at a scale of 1:100,000, using USGS 1:100,000 DRGs as a backdrop for heads up digitizing. Huntarea boundary descriptions are part of hunting regulations, which are approved and published annually by the Wyoming Game and Fish Commission. When needed, the 2008 edition (1st Edition) of the Wyoming Road and Recreation Atlas (Benchmark Maps) was consulted for road and other information.
The USGS SAGEMAP provides a GIS Database for Sage Grouse and Shrubsteppe Management in the Intermountain West. SAGEMAP provides documents on recient developements, information, interactive maps, and data concerning sage ecological communities in the US.

Summary and Initial Evaluation of Enduring Features Information for the Conterminous USA, with Evaluation of Potential Use for Ecoregion Assessment
Concerns about the influence of climate change on biota have emerged over the past decade, and responses in species populations and distribution patterns have already been documented (Parmesan 1996, Thomas and Lennon 1999). Current climates and communities will not simply migrate, but rather will re-form in novel ways over time (Fox 2007; Hunter et al. 1988; Williams and Jackson 2007). Due to the uncertainty of future climatic patterns and species responses, enduring features of the landscape (geophysical settings) are appropriate targets of assessment, planning, and conservation (Anderson and Ferree 2010, Beier and Brost 2010, Brost and Beier 2012; Hunter et al. 1988). Only recently have enduring features been...
We propose to support the revision and implementation of the South Atlantic Landscape Conservation Cooperative’s Conservation Blueprint by integrating its Ecosystem Indicators into a structured decision support system that makes explicit how the Indicators are interrelated and how these will respond to management and policy interventions aimed at improving the conservation status of the South Atlantic region. Our specific objectives are to (1) develop ecological production functions that predict theecological impacts of selected conservation actions relative to current conditions, and to propagate these impacts through other affected systems or functions; (2) codify protocols for updating and curating geospatial...
