1965 tamarisk point data for the Colorado Plateau ecoregion, USA Over the past 100 years, species of non-native tamarisk (Tamarix spp.) have invaded perhaps hundreds of thousands of acres in riparian zones and desert washes throughout the semi-arid, west and southwest United States (Robinson 1965, Cleverly et al. 1997). Large stands of tamarisk transpire vast amounts of precious water supplies, negatively alter soil chemistry, and out-compete native plant species (Zimmerman 1997, Di Tomaso 1998, Smith et al. 1998, Zavaleta 2000). Tamarisk is a prolific seeder, consummate resprouter, and is fire tolerant. Tamarisk has negative effects on many wildlife species, but it can act as marginal replacement habitat for some...
This dataset provides a measure of near-term high development, as an integration of several factors representing landscape development. This measure was calculated using a fuzzy logic model, which is represented in graphical format in \Vector\Change_Agents\Development\Documentation\COP_DV_logic_models.pptx This dataset represents the combination of energy, agriculture, urban, and recreation development. Original source data were summarized to 4KM reporting unit, and converted to fuzzy values (rescaled on a -1 to 1 value range) for input to the fuzzy logic model. These data include: utility lines, pipelines (from BLM), oil/gas wells (from BLM), oil/gas well anticipated development (from Holly Copeland 2009), mines...

GunnSageGrouseWinterRange is an ESRI SDE Feature Class showing observed winter range of Gunnisons Sage-Grouse. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35). Dataset was acquired from a third party distributor who obtained it from CDOW in January 2011. The authoritative data source is available on ArcGIS.com (http://www.arcgis.com/home/item.html?id=1bab23cd9f274742ae1e38afa6e6c44f) and...
This dataset shows the current distribution of Colorado Plateau Pinyon-Juniper Woodland (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 absolute...
U.S. Cities represents locations for cities within United States with populations of 10,000 or greater (based on Census 2000 figures), all state capitals, and the national capital.
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 presents special designations 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 absolute changes in runoff, precipitation, temperature, and vegetation change...
This dataset provides an estimate of water-based recreation travel corridors, based on a combination of wild and scenic rivers, and major rivers selected from NHD that were listed on the BLM rivers website. All reaches of these rivers were selected, as insufficient information exists to determine what segments may or may not be open to recreation. Other areas may be open to water-based recreation travel than are represented in this dataset.
WTPrairieDogOverallRange is an ESRI SDE Feature Class showing an area which encompasses all known seasonal activity areas within the range of a population of white-tailed prairie dogs. This information was derived from field personnel. A variety of data capture techniques were used including drawing on mylar overlays at 1:50,000 scale USGS county mapsheets and implementation of the SmartBoard Interactive Whiteboard using stand-up, real-time digitizing at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing Mapping Resources. GeoWorld 16(3):32-35).
This map shows perennial rivers and streams from the National Hydrography Dataset. Not all perennial features were identified as perennial rivers and streams (e.g., artificial paths). These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions.

These data may not have the accuracy, resolution, completeness, timeliness, or other characteristics appropriate for applications that potential users of the data may contemplate. The User is encouraged to carefully consider the content of the metadata file associated...
This dataset shows a series of fragmentation metrics for natural vegetation for a watershed (HUC5) 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 A 90 meter edge distance was used to define core area within patches.
5th Code HUC reporting units for the Colorado Plateau Ecoregion Used as analytical reporting units for aquatic conservation elements.
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 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
