This zip file contains 24 raster layers representing data from a variety of landscape metrics used to analyze the landscape context of the greater Yellowstone area. Their names, descriptions and categorization are as follows:

Housing This raster dataset contains seventeen housing layers which are all named in the format "bhc1940," where ‘bhc’ is Built Housing Capacity and year represents the decades from 1940 through 2100. The layers depict the location and density of private land housing unit classes, as described below. The classifications were produced using the SERGoM v3 model (see Theobald, D. 2005. Landscape patterns of exurban growth in the USA from 1980 to 2020. http://www.ecologyandsociety.org/vol10/iss1/art32). These data are based on existing US Census datasets and growth projections.

Land Cover Land cover and impervious surface data comes from version 2 of the circa 2001 National Land Cover Dataset (NLCD), the circa 2006 NLCD, and the NLCD 2001/2006 Land Cover Change product, which was acquired from the Multi-Resolution Land Characteristics Consortium. The names and descriptions of the five land cover raster layers are as follows:

• NLCD_2001v2. This raster layer depicts 16 land cover classes using data from version 2 of the circa 2001 National Land Cover Dataset.

• NLCD_2006. This raster layer depicts 16 land cover classes using data from the circa 2006 National Landcover Database.

• LandCover_2001. This raster layer depicts 16 land cover classes using data from the circa 2001 National Land Cover Dataset.

Land cover classes for NLCD_2001, NLCD_2006 and LandCover_2001 are shown below.

Value Land Cover 11 Open Water 12 Perennial Snow/Ice 21 Developed, Open Space 22 Developed, Low Intensity 23 Developed, Medium Intensity 24 Developed, High Intensity 31 Barren Land 41 Deciduous Forest 42 Evergreen Forest 43 Mixed Forest 52 Shrub/Scrub 71 Herbaceous 81 Hay/Pasture 82 Cultivated Crops 90 Woody Wetlands 95 Emergent Herbaceous Wetlands

• ImperviousSurfaces_2001. This raster layer represents impervious surfaces using data from the circa 2001 National Land Cover Dataset.

• ImperviousSurfaces_2006. This raster layer represents impervious surfaces using data from the circa 2006 National Landcover Database.

• LandCoverChange_2001_2006. This raster layer represents land cover change from 2001 to 2006 using data from the NLCD 2001/2006 Land Cover Change product, which was acquired from the Multi-Resolution Land Characteristics Consortium.

Wildlife - Grizzly_Connectivity. This raster layer represents grizzly habitat connectivity in the GYA. For more information, please consult the corresponding reference citations from the report.

Agriculture - GYA_Agriculture is a CSV file containing tabular county-level data from the 2002 and 2007 U.S. Department of Agriculture (USDA) Census of Agriculture. Data were obtained from National Agriculture Statistics Service (NASS).
