The download for this dataset includes TNC’s full Northeastern Aquatic Habitat Classification System: stream size, stream temperature, stream gradient, stream geology, lakes and catchments. This dataset represents the results (9/30/2008) of the Northeastern Aquatic Habitat Classification System (NAHCS) GIS map for streams and rivers. This classification focused on mapping a stream habitat types across 13 northeastern states (ME, NH, VT, MA, CT, RI, NY, NJ, PA, MD, DC, DE, VA, WV). Stream and river centerlines were extracted from the USGS National Hydrography Dataset Plus (NH-Plus) 2006 1:100,000 data. These reaches were attributed and placed into classes representing their biopysical setting in terms of stream...

This project developed a series of maps depicting the distribution and probability of occurrence of marine birds in the northwestern Atlantic Ocean. The maps are intended to be used for informing decisions about siting offshore facilities; marine spatial planning; and other uses requiring maps of seabird distributions.
This online database (https://www.streamcontinuity.org/cdb2/naacc_search_crossing.cfm) serves as a common repository for road-stream crossing assessment data assembled by the North Atlantic Aquatic Connectivity Collaborative (NAACC). Both a network of partners and a source of shared resources, the NAACC offers a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings across the region that represent barriers to wildlife movement and pose flooding risks to communities. The NAACC offers training in standard protocols for conducting assessments, online tools for prioritizing upgrades based on ecological benefits, and this database...

The Northeast Regional Conservation Framework Workshop, held in June 2011, provided an opportunity to step back and synthesize the results of many projects that have been completed or are underway through the Northeast Association of Fish and Wildlife Agencies Regional Conservation Needs (RCN) program and Landscape Conservation Cooperatives (LCCs). The workshop also helped partners determine how these projects might fit into a common regional conservation framework and identify the greatest needs for future work. By fostering information sharing and discussions among regional conservation experts, the workshop sought to clarify the “big picture” of conservation, illuminate how existing efforts complement each other,...
This project brings together the major partners involved in road-stream crossings to assess river and stream continuity and set priorities for restoring connectivity, and reducing flood damage to road crossings, within the North Atlantic region.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
