National Fish Habitat Partnership (NFHP) 2015 Cumulative Habitat Condition Scores and Disturbance Indices Linked to HUC 12 Watersheds of the Watershed Boundary Dataset

This shapefile contains fish habitat condition index (HCI) scores as well as specific disturbance indices for 6th level Hydrologic Unit Code (HUC12) watersheds of the Watershed Boundary Dataset. The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for assessing fluvial fish habitat; (2) consistent across the entire study area i

National Fish Habitat Partnership (NFHP) 2015 Cumulative Habitat Condition Scores and Disturbance Indices Linked to Catchments of Southeast Alaska

This shapefile contains cumulative fish habitat condition index (HCI) scores as well as specific disturbance indices for local and network catchments of Southeast Alaska. Catchments creation was leveraged through a project occurring at Michigan State University (Ross 2013). The source datasets compiled and attributed to spatial units were identified as being: (1) meaningful for asse

Shapefiles and Historical Aerial Photographs, Little Missouri River, 1939-2003

The data archive contains the aerial photographs and channel delineations used in our analysis. The images have been geo-referenced to the 1995 digital orthophoto quarter quadrangles as described by Miller and Friedman (2009). The separate images for each year can be viewed as a composite along with that year’s channel delineation using a geographic information system (GIS). The 2

Species of Greatest Conservation Need Analysis Tool

Species of Greatest Conservation Need are lists of species designated in the 56 State Wildlife Action Plans which identify the species most in need of conservation action in that state or U.S. territory. USGS developed a process that allows these lists to be compiled into a national list, making their representation across taxa groups available via the Species Conservation Analysis Tool.
