Zonal statistic was used to determine the percentage of Level 2 large Intact Blocks in a grazing allotment.
This 1-kilometer resolution raster (grid) dataset is an index of mean annual natural ground-water recharge. The dataset was created by multiplying a grid of base-flow index (BFI) values by a grid of mean annual runoff values derived from a 1951-80 mean annual runoff contour map. Mean annual runoff is long-term average streamflow expressed on a per-unit-area basis. The concept used to construct the dataset is based on two assumptions: (1) long-term average natural ground-water recharge is equal to long-term average natural ground-water discharge to streams, and (2) the base-flow index reasonably represents, over the long term, the percentage of natural ground-water discharge in streamflow.

Cheatgrass Cover based on Peterson (2006, 2007).
U.S. States represents the 50 states, the District of Columbia, and Puerto Rico of the United States.This dataset was used in the Northern Great Basin Rapid Ecoregional Assessment by BLM. No changes were made to the data but the dataset states within the ecoregion (California, Idaho, Nevada, Oregon, Utah and Wyoming.
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...
Protected areas are cornerstones of national and international conservation strategies. By way of these designations, lands and waters are set-aside in-perpetuity to preserve functioning natural ecosystems, act as refuges for species, and maintain ecological processes. Complementary conservation strategies preserve land for the sustainable use of natural resources, or for the protection of significant geologic and cultural features or open space. PAD-US 1.1 (CBI Edition) attempts to include all available spatial data on these places. It is our goal to publish the most comprehensive geospatial data set of U. S. protected areas to date. PAD-US 1.1 (CBI Edition) is limited to the continental U.S., Alaska, and Hawaii....
A 10 km moving window was used on the Other Conifer conservation element to determine the relative density of Other Conifer within the moving window.
This dataset was developed by the USGS for use in regional climate simulation analyses. These data were applied in the BLM REA analysis for the NGB ecoregion. For more information pertaining to these data and climate modeling, please refer to http://regclim.coas.oregonstate.edu/.
Agricultural areas were extracted from state vegetation mapping and their location was compared to location of identified breeding bird density (75%) areas. Breeding bird density areas were mapped by Doherty et al. 2010.16 - 32 % agriculture = moderate> 32 % agriculture = low quality
Mineral resource occurrence data covering the world, most thoroughly within the U.S. This database contains the records previously provided in the Mineral Resource Data System (MRDS) of USGS and the Mineral Availability System/Mineral Industry Locator System (MAS/MILS) originated in the U.S. Bureau of Mines, which is now part of USGS. The MRDS is a large and complex relational database developed over several decades by hundreds of researchers and reporters. This product is a digest in which the fields chosen are those most likely to contain valid information.These locations were buffered and converted to a raster to be included in a large mosaic of development layers.
