Foothills Aspen Distribution Functional Type no null values
Core area risk is classified by the percent of aspen that is core area, summarized by township. Core area was defined as aspen greater than 60 m from nonforest edges and roads or railroads.
Ranks of landscape level ecological risks for pygmy rabbit, summarized by township, in the Wyoming Basin Rapid Ecoregional Assessment project area. Landscape level risk based on Terrestrial Development Index (TDI). Risk classes based on mean TDI score by township. Lowest risk corresponds to TDI less than 1, medium risk corresponds to TDI 1 to 3, Highest risk corresponds TDI greater than 3. See table 27.3 and appendix in the Wyoming Basin REA report at http://pubs.er.usgs.gov/publication/ofr20151155 for additional details.
The potential effect of development on patch size was used as an index of fragmentation. Patch size was quantified for baseline conditions for pygmy rabbit. This provides a reference for comparing patch size for relatively undeveloped patches (Terrestrial Development Index scores less than or equal to 1 percent) of pygmy rabbit.
Federal protected areas such as national parks and preserves and wildlife refuges cover large areas of the study area. Because of its remote location, few people visit the region for recreational use, and except for the Iditarod, activities are concentrated in the summer. Recreation in the region includes sport hunting, sport fishing, and general outdoor hiking and camping activities.
This dataset shows unsettled state and native land claims at the section level filtered from general land status records in 2011 Land Information System Database downloaded from ASGDC. The Land Status attributes are a snapshot of the Land Information System Database and are only accurate as that database. The data is produced to the section (square mile) level.
U.S. Counties (Generalized) represents the counties of the United States in the 50 states and the District of Columbia. These data were reprojected to USA_Contiguous_Albers_Equal_Area_Conic_USGS_version and clipped to the MAR REA boundary.
Raster dataset (30m resolution mask containing only "1" values) matching the 1 km resolution reporting units grid created for the Colorado Plateau Ecoregion.This dataset was used in the Utah-Colorado Plateau REA Stepdown terrestrial intactness analysis for summarizing raster input data to 1 km reporting units.
The potential effect of development on patch size was used as an index of fragmentation. Patch size was quantified for baseline conditions for Greater Sage Grouse. This provides a reference for comparing patch size for relatively undeveloped patches (Terrestrial Development Index scores less than or equal to 1 percent).
This raster dataset represents Places II: Specially Designated Areas of Ecological and Cultural Value within the Mojave Basin and Range. These sites represent legally protected lands and waters. Plus lands that have been identified as known recovery lands (e.g. critical habitat recommended for recovery of Desert Tortoise and recovery units identified for the CA red legged frog).
This simple assessment raster is used to answer management questions (MQs) about where change agents (CAs) overlap with BLM high biodiversity sites (HBS) in the Central Great Basin and Range Ecoregion. This is a basic footprint assessment of anthropogenic features (urban development, roads, etc) intersect with the areas of HBS. The HBS were derived from source data characterizing locations with concentrated at-risk biodiversity or existing source data of a prioritization exercise that identified areas of high conservation significance. It does not model actual response or condition of the HBS to the CAs. The data intersects two primary classes of information: The CAs consist of 19 classes which represent different...
The study area for this Rapid Ecoregional Assessment (REA) COP 2014
This simple assessment layer is used to answer management questions (MQs) about which high biodiversity sites (HBS) will experience significant climate change in the near future scenario in the Mojave Basin and Range Ecoregion. This is a basic intersect of areas that will likely experience significant climate change effects with the areas that have been identified by previous 3rd party analyses as having extraordinary biodiversity. It does not model actual response or condition of the HBS to climate change. Nearly all HBS in the ecoregion will experience significant effects according to the criteria that were selected. The climate space trends data layer was used to ascertain areas of significant climate changes....
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...
Fifth-level watersheds (HUC10) with high or very high conservation potential for at least one aquatic species evaluated as a Conservation Element by land ownership and protection from PADUS.
