Wild and Scenic Rivers 2018 Linked to the NHDPlusV2.1

These data depict the National Hydrography Dataset Plus Version 2.1 (NHDPlusV2.1) flowline representation of the National Wild and Scenic Rivers System throughout the conterminous United States as of 2018. U.S. Forest Service geospatial data on National Wild and Scenic River segments (USFS WSR Segment) from 3/1/2016 were joined to the NHDPlusV2.1 to create the Wild and Scenic Rivers 2018 Linked to the NHDPlusV2.1 (wsr_nhdpv2.1) data. To ensure these data correctly represented the NHDPlusV2.1 flowline delineation of the National Wild and Scenic Rivers System, each wsr_nhdpv2.1 river segment was examined against the USFS WSR Segment data to check for duplication and/or omission of Wild and Scenic River segments.

Conterminous United States Land Cover Projections - 1992 to 2100

The USGS’s FORE-SCE model was used to produce land-use and land-cover (LULC) projections for the conterminous United States. The projections were originally created as part of the "LandCarbon" project, an effort to understand biological carbon sequestration potential in the United States. However, the projections are being used for a wide variety of purposes, including analyses of the effects of landscape change on biodiversity, water quality, and regional weather and climate. The year 1992 served as the baseline for the landscape modeling. The 1992 to 2005 period was considered the historical baseline, with datasets such as the National Land Cover Database (NLCD), USGS Land Cover Trends, and US Department of Agriculture's...

Aquatic Ecoregions of the Conterminous United States

Ecoregions are based on perceived patterns of a combination of causal and integrative factors including land use, land surface form, potential natural vegetation, and soils (Omernik, 1987).

WBD HU12 Pour Points derived from NHDPlus

Pour points derived from NHDPlus V2.1 flow direction rasters and the NHDPlus V2.1 WBD HU12 snapshot. Three sets of pour points are provided: From (fpp) and to (tpp) points that identify the location where raster flow leaves the HU12 polygon, and a third "vector pour point" (vpp) selected "upstream" for use in detecting flow confluences near the raster pour point locations. This dataset is PROVISIONAL and SUBJECT TO REVISION.

The Relative Impacts of Climate and Land-use Change on Conterminous United States Bird Species from 2001 to 2075

Species distribution models often use climate data to assess contemporary and/or future ranges for animal or plant species. Land use and land cover (LULC) data are important predictor variables for determining species range, yet are rarely used when modeling future distributions. In this study, maximum entropy modeling was used to construct species distribution maps for 50 North American bird species to determine relative contributions of climate and LULC for contemporary (2001) and future (2075) time periods. Results indicate species-specific response to climate and LULC variables; however, both climate and LULC variables clearly are important for modeling both contemporary and potential future species ranges....

Bailey's Ecoregions of the Conterminous United States

This multi-tiered, broad-scale, hierarchical system of ecoregions is based on numerous environmental variables at each level. The first two tiers are based on climate, followed by climate and physiograpghy, and finally topography and soils. This data was used to provide a general description of the ecosystem geography.
