Initial HCI scores were developed using landscape factors representing human disturbances summarized to local and network catchments of river reaches throughout the Conterminous United States. Habitat condition scores were based on responsiveness of biological metrics to anthropogenic landscape disturbances throughout ecoregions. Separate scores were created by considering disturbances within local catchments, network catchments, and a cumulative score that accounted for the most limiting disturbance...

These data provide the geographic extent within which the USGS Gap Analysis Project delineates areas of suitable habitat for terrestrial vertebrate species in their species' habitat maps. The range maps are created by attributing a vector file derived from the 12-digit Hydrologic Unit Dataset (USDA NRCS 2009). Modifications to that dataset are described here. Attribution of the season range for each species was based on the literature and online sources (See Cross Reference section of the metadata). Attribution for each...

This area overlaps with the Prairie Pothole Region and greater than 35% of wetlands are less than or equal to 1 km from a petroleum-related well. Legacy practices often released saline co-produced waters (brines) that were chloride rich wastes, affecting wetland water quality directly or persisting in sediments. Despite the potential threat of brine contamination to aquatic habitats, there has been little research into their ecological effects. We capitalized on a gradient of legacy brine-contaminated wetlands in northeast Montana to conduct laboratory...
