title: Greater Yellowstone Area Landscape Dynamics, GeoPackage

description: This geopackage contains sixteen layers representing data from a variety of landscape metrics used to analyze the landscape dynamics of the Greater Yellowstone Area. Their names, descriptions and categorization are as follows:

Study Area 
- GYCC_GYA_AreaOfAnalysis. This polygon, as defined by the Greater Yellowstone Coordinating Committee (GYCC), represents the Greater Yellowstone Area (GYA) and serves as the primary area of analysis for most of the indicators described in the report.

- SonoranInstitute_AreaOfAnalysis. These polygons represent the 34 counties considered most influential in terms of regional land use characteristics and serve as a second area of analysis. Produced by the Sonoran Institute.


Conservation Status 
- PADUS1_2. This feature layer includes polygons from the Protected Areas Database of the United States (PADUS) version 1.2, which originates from the US Geological Survey (USGS) Gap Analysis Program (GAP). The PAD-US is a geodatabase that illustrates and describes public land ownership, management and conservation lands nationally, including voluntarily provided privately protected areas. The lands included in PAD-US are assigned conservation measures that qualify their intent to manage lands for the preservation of biological diversity and to other natural, recreational and cultural uses; managed for these purposes through legal or other effective means. 


Population
- Hydro_features. The polygons in this feature layer represent the water feature areas (for example, bays, glaciers, lakes, and swamps) of the Western half of the United States as determined by the National Atlas of the United States and the United States Geological Survey (USGS).  

- CensusBlockGroups_1990 This feature class contains block group polygons, population totals and calculated population attributes for the 1990 Census. Population values come from the U.S. Census Bureau. 

- CensusBlockGroups_2000. his feature class contains block group polygons, population totals and calculated population attributes for the 2000 Census. Population values come from the U.S. Census Bureau.

- CensusTracts_GYA_2010. This feature layer contains polygons representing census tracts in the GYA based on U.S. Census Bureau data from 2010. Source data, TIGER/Line Shapefile, 2010, 2010 state, Idaho, 2010 Census Tract State-based, originates from the U.S. Department of Commerce, U.S. Census Bureau, Geography Division. 

- CensusBlockGroups_GYA_2010. This feature layer contains polygons representing census block groups in the GYA based on U.S. Census Bureau data from 2010. Source data, TIGER/Line Shapefile, 2010, 2010 state, Idaho, 2010 Census Block Group State-based, originates from the U.S. Department of Commerce, U.S. Census Bureau, Geography Division.


Roads
- Traffic_Points. This feature layer contains points representing locations of Automatic Traffic Count Stations (ATR) and annual average daily traffic counts using data from the Federal Highway Administration's (FHWA) Research and Innovative Technology Administration's Bureau of Transportation Statistics (RITA/BTS).

- Streets. This feature layer contains polylines that represent detailed streets, interstate highways, and major roads in and around the Greater Yellowstone Area. This data set is from the 2003 Tele Atlas Dynamap Transportation version 5.2 product.

- Major_Roads. This feature layer contains polylines that represent the major roads of the United States and Canada. These include interstates, inter-metropolitan area, and intra-state highways and major roads.


Wildlife
- MuleDeerHabitat. This feature layer contains polygons representing habitat ranges for mule deer within the GYA. 

- GrizzlyHabitat_50sqkm. This feature layer contains polygons representing potential grizzly bear core areas at least 50 square kilmeters in size. The area of each polygon is included in the attributes table. Data originates from modeled grizzly bear core habitat as part of a wildlife movement corridor models by the Craighead Institute.

- GrizzlyHabitat_250sqkm. This feature layer contains polygons representing potential grizzly bear core areas at least 250 square kilometers in size. These core areas were used for the connectivity portion of the analysis. 

- WolverineHabitat. This feature layer contains polygons representing wolverine habitat. 

- UngulateMigration. This feature layer contains polylines representing large mammal migration routes for five ungulate species (elk, mule deer, bighorn sheep, moose, and pronghorn) in the Greater Yellowstone Ecosystem, as compiled from GIS data on migration route locations for Wyoming, Montana, and Idaho. Estimates of distribution were originally made by the Wildlife Conservation Society.
