The distribution and abundance of Colorado River cutthroat trout (Oncorhynchus clarkii pleuriticus; CRCT) have declined from historical levels over their entire range. For this CRCT assessment we used existing information provided by 48 fisheries professionals applied through a consistent methodology to assess the extent of CRCT historical range, their current distribution, including genetic status, and evaluated the foreseeable risks to 285 populations designated as "conservation populations" by management agencies. We estimated CRCT historically occupied about 21,386 miles of habitat in the western U.S. CRCT currently occupy about 3,022 miles of habitat in 51 of the 61 4th level HUCs historically occupied. Of...

Average Annual Temperature (2015-2030) simulated by RegCM3 with ECHAM5 projections as boundary conditions. Units are degrees Celsius. These data were generated by the regional climate model RegCM3 with boundary conditions from a GCM future climate projections. The data were downscaled statistically by calculating differences (anomalies) between the RegCM3 results with GCM-driven boundary conditions for 1968-99 and those for a future period, in this case 2015-2030. The anomalies were added (temperatures) or multiplied (precipitation) to a climate baseline from PRISM (Parameter-elevation Regressions on Indepenent Slopes Model - prism.oregonstate.edu) data based on historical observations. The PRISM baseline was calculated...

In a step towards implementing our Vision, SREP completed a statewide assessment of wildlife linkages in collaboration with the Colorado Department of Transportation (CDOT), the Federal Highway Administration, The Nature Conservancy, and Colorado State University, identifying and prioritizing wildlife linkages across the state of Colorado. The goal of this work is to provide transportation planners, state and federal agencies, community leaders, engineers, and conservationists with a statewide vision for reconnecting habitats that are vital for maintaining healthy populations of native species. Both the Federal Highway Administration and CDOT have begun promoting wildlife crossings in their transportation plans...

The LANDFIRE existing vegetation layers describe the following elements of existing vegetation for each LANDFIRE mapping zone: existing vegetation type, existing vegetation canopy cover, and existing vegetation height. Vegetation is mapped using predictive landscape models based on extensive field reference data, satellite imagery, biophysical gradient layers, and classification and regression trees. DATA SUMMARY: The existing vegetation height (EVH) data layer is an important input to LANDFIRE modeling efforts. Canopy height is generated separately for tree, shrub and herbaceous cover life forms using training data and a series of geospatial data layers. EVH is determined by the average height weighted by species...

The Geospatial Multi-Agency Coordination Group, or GeoMAC, is an internet-based mapping tool originally designed for fire managers to access online maps of current wildland fire locations and perimeters in the continental United States, including Alaska. Perimeters are submitted to GeoMAC by the incidents via posting to FTP and web sites for downloading. This file contains wildland fire perimeters submitted to GeoMAC from the year 2000 to the calendar year preceeding the current one. The projection is geographic and the datum is NAD83. Last updated January 20, 2011, SPW. Additional metadata available at: http://rmgsc.cr.usgs.gov/outgoing/GeoMAC/historic_fire_data/us_hist_fire_perimeters_dd83_METADATA.htm

This dataset shows the current distribution of Inter-Mountain Basins Montane Sagebush Steppe (NatureServe Landcover) within the context of current and near-term terrestrial intactness and long-term potential for energy development and potential for climate change (4KM reporting units). Current terrestrial intactness is based on current measures of landscape development, fire regime and vegetation impacts, and fragmentation. Near-term intactness includes estimates of urban growth and expansion of invasive vegetation. Long-term potential for energy development is based on areas of potential for wind, solar, and petroleum development derived from multiple sources. Long-term potential for climate change is based on...

This dataset represents PRONGHORN use areas in Utah as determined by wildlife biologists first during 2001. The data for Carbon, Emery, Grand, Wayne, Garfield, and San Juan were updated by state and federal agency biologists March 2004. Another update was completed in November 2004 in conjunction with the Richfield BLM RMP process. An update in Uintah county by UDWR biologists was completed in January 2006. In May 2006 the dataset was converted from a Critical, High, Substantial and Limited value system to a Crucial/Substantial value system. In 2010, Uintah county biologist added two crucial yearlong areas to the file. Data for use at 1:100,000 scales.

This dataset shows a series of fragmentation metrics for natural vegetation for a 4KM reporting unit. These metrics were calculated using FRAGSTATS. For more information about FRAGSTATS, or the methods used to calculate these metrics, please see: http://www.umass.edu/landeco/research/fragstats/fragstats.html Fragmentation metrics were caculated for a 3x3 reporting unit grid (4KM each) neighborhood centered on each reporting unit grid cell. This was done to prevent edge effects due to the smaller size of the reporting units relative to the size of larger patches in more intact landscapes. A 90 meter edge distance was used to define core area within patches.

Broad-scale alterations of historical fire regimes and vegetation dynamics have occurred in many landscapes in the U.S. through the combined influence of land management practices, fire exclusion, ungulate herbivory, insect and disease outbreaks, climate change, and invasion of non-native plant species. The LANDFIRE Project produces maps of simulated historical fire regimes and vegetation conditions using the LANDSUM landscape succession and disturbance dynamics model. The LANDFIRE Project also produces maps of current vegetation and measurements of current vegetation departure from simulated historical reference conditions. These maps support fire and landscape management planning outlined in the goals of the National...

Two future climate change scenarios at a resolution of 0.5 degree latitude/longitude for the conterminous United States were used in the Vegetation Ecosystems Modelling Analysis Project (VEMAP): a moderately warm scenario produced by the general circulation model from the Hadley Climate Centre [Johns et al., 1997; Mitchell and Johns, 1997], HADCM2SUL (up to a 2.8oC increase in average annual U.S. temperature in 2100) and a warmer scenario (up to a 5.8oC increase in average annual U.S. temperature in 2100), CGCM1, from the Canadian Climate Center [Boer et al., 1999a, 1999b; Flato et al., 1999]. Both general circulation models (GCMs) included sulfate aerosols and a fully dynamic 3-D ocean. Both transient scenarios...

New invasions, better field data, and novel spatial modeling techniques often drive the need to revisit previous maps and models of invasive species. Such is the case with the at least 10 species of Tamarix, which are invading riparian systems in the western United States and are expanding their range throughout North America. In 2006, we developed a National Tamarisk Map using a compilation of presence and absence locations with remotely sensed data and statistical modeling techniques. Since the publication of that work, our database of Tamarix distributions has grown significantly.Using the updated database of species occurrence, new predictor variables, and the Maximum entropy (Maxent) model, we have revised...

Because of the potential for reindeer to commingle into caribou herds when the two occupy the same range or when caribou migrate through reindeer range, areas within current caribou herd summer ranges were considered to have low biological potential to support reindeer herding for calving season and summer. Similarly, areas within the current herd annual ranges were considered to have low biological potential to support reindeer herding for late fall, winter, and early spring. Areas of moderate and good quality forage occurred both within and outside of caribou herd ranges for both assessed seasons within the Central Yukon study area but to widely differing extents. The summer ranges of all caribou herds covered...
