NatureScape, Aquatic Appalachian LCC Final Watershed Scores

Aquatic connectivity was modeled across the entire Landscape Conservation Cooperative geography at the catchmentand watershed scales. To evaluate aquatic connectivity, the density of dams and road crossings was used as these areknown to disrupt connectivity within aquatic systems. Connectivity data for dams and road crossings werecreated from the StreamCat database. The density of dams and roads was multiplied, at the catchment and watershedlevels, by the relative influence of each connectivity variable in the Boosted Regression Tree (BRT) models and then the connectivity variables were averaged. A single aquatic connectivity score was then assigned to each catchment. This aquaticconnectivity score was used to modify...

Anthropogenic Disturbances and Natural Variables in the Conterminous United States Linked to Catchments and Buffers of the National Hydrography Dataset Plus Version 2.1

This USGS data release contains landscape variables representing anthropogenic disturbances to stream habitats and natural variables summarized within local and network stream catchments of the National Hydrography Dataset Plus Version 2.1 (NHDPlusV2.1) as well as a 90 meter local and network buffer of stream reaches throughout the conterminous U.S. The source datasets compiled and attributed to spatial units were identified as being: (1) consistent extent across the entire study area; (2) broadly representative of conditions in the past 20 years, and (3) of adequate spatial resolution that they could be used to make valid comparisons among local catchment units. Variables summarized at the catchment scale include...
