We assessed development levels in spadefoot assemblage based on the regional Terrestrial Development Index (TDI) map, and then used the resulting output to calculate patch size and structural connectivity metrics. We mapped the structural connectivity of relatively undeveloped areas (TDI less than or equal to 1 percent) at two inter patch distances based on connectivity analysis; local (0.27 km), landscape (3.51 km). See Chapter 2 Assessment Framework and Appendix of the Wyoming Basin REA Open File Report at http://pubs.er.usgs.gov/publication/ofr20151155 for additional details.
This data set represents the GIS Version of the Public Land Survey System including both rectangular and non-rectangular surveys. The primary source for the data is cadastral survey records housed by the BLM supplemented with local records and geographic control coordinates from states, counties as well as other federal agencies such as the USGS and USFS. The data has been converted from source documents to digital form and transferred into a GIS format that is compliant with FGDC Cadastral Data Content Standards and Guidelines for publication. This data is optimized for data publication and sharing rather than for specific "production" or operation and maintenance. This data set includes the following: PLSS Fully...
Information provided by Colorado Parks and Wildlife identifying sixth-level watersheds (HUC-12) with occurrence of any of the three-fish species (bluehead sucker, flannelmouth sucker or roundtail chub).
Map displays probability of suitable habitat for tamarisk during a future period of 2016 to 2030.
The Individual Tree Species Parameter Maps (ITSP) were developed to support the National Insect and Disease Risk Map (NIDRM) since insect and disease risk is often driven by the density of a given species. While similar to the Tree Atlas, the ITSP project mapped basal area and stand density index for each individual tree species. The parameter products are based on 30 meter Landsat satellite data, climate, terrain, and soil predictor layers and ground samples from the USFS Forest Inventory and Analysis plot data. Many other applications and analyses requiring tree species density could benefit from this spatially refined dataset. Data were supplied to USGS by Vern Thomas from the USDA Forest Service in Fort Collins....
Structural connectivity of baseline mule deer crucial winter range in the Wyoming Basin Rapid Ecoregional Assessment project area. We mapped the structural connectivity for local connectivity (1.8km), landscape connectivity (5.31km), and regional connectivity (11.79km).. See Chapter 2 Assessment Framework and Appendix of the Wyoming Basin REA Open File Report at http://pubs.er.usgs.gov/publication/ofr20151155 for additional details.
This map shows the current predicted distribution of desert tortoise (Mojave and Sonoran populations), along with current and near-term status, and long term potential for change.

To map connectivity, we assessed development levels for relatively undeveloped areas based on the regional Terrestrial Development Index (TDI) map (TDI scores less than or equal to 1 percent), and then used the resulting output to calculate patch size and structural connectivity metrics. We mapped the structural connectivity of relatively undeveloped areas (TDI less than or equal to 1 percent) at three inter patch distances based on connectivity analysis; local (1.8 km), landscape (2.25 km), and regional (3.51 km) scales. See Chapter 2 Assessment Framework and Appendix of the Wyoming Basin REA Open File Report for additional details at http://pubs.usgs.gov/of/2013/1223/.
Terrestrial Development Index (TDI) for transportation in the Wyoming Basin REA project area. TDI scores are based on the percent of transportation surface disturbance footprint from development within a 2.25 km radius moving window for a 15m cell size. The TDI quantifies the total area of transportation surface disturbance footprint. TDI scores range from 0 to 100 percent and were divided into seven classes for visualization purposes. Because the development scores are continuous, alternative classes can be used to display the data to address a particular management question. For additional information see the Development Chapter 4 and the Appendix in the Wyoming Basin REA Open File Report.

Average annual temperature for 2076-2090 projected by the GFDL 2.1 GCM run 1 driven by the A2 emissions scenario at 1/8 degree latitude-longitude (approximately 12km by 12 km) over the Wyoming Basin and surrounding areas.

The 303(d) Listed Impaired Waters program system provides impaired water data and impaired water features reflecting river segments, lakes, and estuaries designated under Section 303(d) of the Clean Water Act. Each State will establish Total Maximum Daily Loads (TMDLs) for these waters. Note the CWA Section 303(d) list of impaired waters does not represent waters that are impaired but have an EPA approved TMDL established, impaired waters for which other pollution control mechanisms are in place and expected to attain water quality standards, or waters impaired as a result of pollution and is not caused by a pollutant; therefore, the "Impaired Waters" layers do not represent all impaired waters reported in a state's...
The dataset represents the work of multiple states and Federal agencies as part of the US Gap Analysis and LandFire programs. Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform) to model natural and semi-natural vegetation. The minimum mapping unit for this dataset is approximately 1 acre. Landcover classes are drawn from NatureServe's Ecological System concept. Five-hundred and fourty-four land cover classes composed of 12 cultural and 532 Natural/Semi-natural types are described. Land cover classes were mapped with a variety of techniques including decision tree classifiers, terrian modeling, inductive...

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...
This creates a Terrestrial Development Index score using just energy, minerals, roads, and railroads to address a management question for mule deer. There is evidence from the published literature that mule deer avoid these development variables, so we used a subset of the overall TDI input variables to evaluate.
