This data set shows forests of North America, classified according to FAO ecological zones (EZ). The data set was created by modifying the Ecological Regions of North America (ecoregions) data included in the North American Atlas. Ecoregion classifications were converted to the FAO EZ classes, based on the Forest Resource Assessment (FRA) 2010, and minor adjustments were made to polygon geometry. In addition, data were added for Hawaii and Puerto Rico, and additional lakes were imported. The FAO ecological zones are based on a combination of climate (temperature and precipitation) and potential vegetation classifications. They are broad areas of relatively homogeneous vegetation, with similar physical characteristics....

This metadata references the polygonal ARC/INFO GIS cover showing the current and historic distribution of potential habitat, or range, of the Greater Sage-grouse (Centrocercus urophasianus) and Gunnison Sage-grouse (Centrocercus minimus) in Western North America. This data was initially researched and compiled by Dr. Michael A. Schroeder, research biologist for the Washington State Department of Fish and Wildlife. The initial draft of current and historic range data was mapped and submitted to state, federal, or provincial natural resource agencies and other experts for review, comment, and editing. The final product represents the best available science and expert review available at the time of compilation.Definition...
We assessed the impacts of co-occurring invasive plant species on fire regimes and postfire native communities in the Mojave Desert, western USA by analyzing the distribution and co-occurrence patterns of three invasive annual grasses known to alter fuel conditions and community structure: Red Brome (Bromus rubens), Cheatgrass (Bromus tectorum), and Mediterranean grass (Schismus spp.: Schismus arabicus and Schismus barbatus), and an invasive forb, red stemmed filaree (Erodium cicutarium) which can dominate postfire sites. We developed species distribution models (SDMs) for each of the four taxa and analyzed field plot data to assess the relationship between invasives and fire frequency, years postfire, and the impacts...

The grizzly bear distribution boundary represents the estimated geographic extent of occupied range of the Yellowstone grizzly bear population for the period 2008-2022. The distribution boundary was delineated to provide reliable estimations of grizzly bear occupancy throughout time and for use as a monitoring tool in grizzly bear management and conservation.The boundary was delineated by the Interagency Grizzly Bear Study Team (IGBST) using an interpolation method based on grizzly bear VHF telemetry and GPS locations as well as verified observations and signs of grizzly bears inside the Greater Yellowstone Ecosystem during 2008 to 2022.

This data set shows Level I, II, and III ecological regions (ecoregions) of North America, and is an update and revision of files developed by Canada, Mexico, and the United States of America in the late 1990’s in a cooperative project for the Commission for Environmental Cooperation (CEC). These revised ecological regions were developed in a meeting between representatives of the three nations and CEC in April 2006 in Newport, Oregon. Ecoregions are areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. The ecoregions in this data set are based on the premise that a hierarchy of ecological regions can be identified through the analysis of the patterns and...

These heatmaps show a top 3 invasive and problematic plant stressor for montane areas in the Chihuahuan Desert, as ranked by participants, and the concentration of participants who reported as working in each municipality or county who also voted for that stressor across the landscape. Symbology represents the percentage of participants with 0% = dark green, 0.0001 % - 24.99% = light green, 25% - 49.99% = yellow, 50% - 74.99% = orange, 75% - 100% = red. All counties and municipalities identified by participants as areas where they work were given a tally for each of the top 3 stressors that participants chose. Counties with a small number of participants were not adjusted for small sample size. These results were...

Boundary for floristic regions used for the conservation assessment of Greater Sage-grouse and sagebrush habitat conducted by the Western Association of Fish and Wildlife Agencies. The floristic provinces were digitized from a figure from Miller, R. F., and L. Eddleman. 2001. Spatial and temporal changes of sage-grouse habitat in the sagebrush biome. Oregon State University, Agricultural Experiment Station. Technical Bulletin 151. This coverage defines the floristic context in which a range-wide conservation assessment of the Greater Sage-grouse and sagebrush habitats was conducted. Defining the major floristic properties of areas occupied by the historical distribution of sage grouse permitted the comparison...

This dataset consists of point features identifying indices for potential passage rate at intersections with major transportation corridors for grizzly bear movements between the Greater Yellowstone Ecosystem (GYE) and Northern Continental Divide Ecosystem (NCDE) in the northwestern United States. Points are spaced at 300-meter intervals along major road corridors (interstates and U.S. highways) and are populated with values from Randomized Shortest Path (RSP) predictive raster models of potential male grizzly bear movement between the two ecosystems as described in Peck et al. 2016 (Potential paths for male-mediated gene flow to and from an isolated grizzly bear population, Ecosphere 8(10):e01969). RSP scores extracted...
A summary data set of all fire polygons we could locate as of December 2007. We used multiple datasets to develop this layer, including data gathered from the internet, publically available databases, and personal contacts with dozens of agency personnel throught the western U.S. Data were assessed for utility (but not accuracy) and formatted for consistency. Each source data set was then attributed consistently with fields for record number and year (of fire). Because various resource management entities map fires somewhat independently (especially in more recent years) we merged overlapping polygons for each year. Users are encouraged to understand the contents of this data file before using it.
