Road Stream Crossing Upgrade Effects, Northeast U.S. This dataset is one of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. This dataset represents the relative potential to improve local aquatic connectivity by upgrading road-stream crossings. The model incorporates survey data from the North Atlantic Aquatic Connectivity Collaborative (NAACC). To view the current NAACC database go to https://streamcontinuity.org/database.htm. The Road Stream Crossing Upgrade Effects dataset and other datasets that augment or complement aquatic connectivity are...

The number of miles that could be gained through conservation action to remove obstructions are summarized by HUC12 watershed units. River/Stream Connectivity is an ecological indicator for the Landscape Conservation Project for Florida. The project entails a large-scale assessment of and planning for the health of important natural resources, known as Conservation Assets (CAs), in Florida. Conservation planning at the landscape scale provides a framework for safeguarding functional ecosystems, and their interconnected processes necessary to achieve true preservation of healthy resources....

Southeast Aquatic Resources Partnership, Streams, Fewer tags BLM REA NGB 2011 Distance to Barriers Assessment for Bighorn Sheep Habitat Barriers were characterized as the minimum distance from forested regions, highways and perennial rivers. Forested regions were extracted from GAP/EVT landcover data by isolating pixels that were classed as ‘forest’. Only forested regions having canopy cover of >80% were selected by using the Landfire canopy cover dataset. TIGER road data was used to identify highways. The USGS National Hydrography Dataset was used to extract perennial stream features. Proximity analyses were applied to all development datasets and scored. Habitat located greater than 1,500 meters away from barriers were considered good, habitat within 400-1,500 meters of barriers were considered fair, and habitat within 400 meters were considered...

Where information exists, fish passage ability is captured. This dataset is maintained and updated on an annual or semi-annual basis. The JUNE, 2012 publication dataset includes almost 60,000 features across the states of Washington, Oregon, Idaho, western Montana and California. Where possible, all barrier locations are georeferenced to StreamNet's regionally standardized routed hydrography layer (MSHv3) enabling comparison and analysis of barrier locations within the context of StreamNet's larger data holdings...
