Land Use/Land Cover: Projected Anthropogenic Disturbance Change 2005-2050 Current data layers were created from data originally produced the USGS(LULC and Carbon projections), called 'CONUS_Historical_2005' and 'CONUS_A2_2050'. Source of original data: Sohl, T.L., Sayler, K.L., Bouchard, M.A., Reker, R.R., Friesz, A.M., Bennett, S.L., Sleeter, B.M., Sleeter, R.R., Wilson, T.S., Knuppe, M., and Van Hofwegen, T., In Press. Spatially explicit modeling of 1992 to 2100 land cover and forest stand age for the conterminous United States. Ecological Applications: http://dx.doi.org/10.1890/13-1245.1 To create the current layer, NLCD classifications within original file were reclassified as follows: 1=Developed (2), 50=Mechanically Disturbed (3,4,5), 101=Agriculture (13,14).

It was developed as part of the Bureau of Land Management’s (BLM) Rapid Ecological Assessment (REA) of this region. Connectivity is defined as the percent of unfragmented landscape (percent area of similar habitat) in a 1 km neighborhood based on ReGAP or GAP land cover data. Values <15% are classified as ‘Low’ connectivity, values of 15-30% are classified as ‘Fair’ connectivity, and values >30% are classified as ‘Good’ connectivity.

This dataset was developed from the Human Footprint inthe western United States (Leu et al. 2008) in order to ease the interpretation of humand footprint comparisons.
