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a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings across the region that represent barriers to wildlife movement and pose flooding risks to communities.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 North Atlantic LCC and Northeast states developed a synthesis of regional conservation information for State Wildlife Action Plan (SWAP) revisions. The compiled information on species and habitats provided a regional context for SWAP elements and has been made available for voluntary inclusion into each state’s Plan via a dynamic, web-based information management system.

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.

This project will updated the 2008 Northeastern Aquatic Habitat Classification (NAHCS) prepared by The Nature Conservancy and the Northeast Association of Fish and Wildlife Agencies (NEAFWA). The updates added a tidal component to the classification of streams and rivers and will enhance lake classification.

The objective of this classification was to create a simplified set of stream and river habitat types based on the Northeast Aquatic Habitat Classification System (Olivero and Anderson 2008) and GIS map for 13 northeastern states (ME, NH, VT, MA, RI, CT, NY, PA, NJ, DE, MD, VA, WV, and DC.) that could be used in the Northeast Stream and River Habitat Guide (available at http://nature.ly/HabGuide). The goal was to collapse the existing 258 types down to ~25 types for reporting in the habitat guide. The habitat guide contains a description of each stream and river type, a distribution map, a photo, associated common and rare species, a crosswalk to state aquatic community types, and a summary of current condition...

We developed a mapped classification of lakes and ponds based on variables that structure lacustrine natural communities and that could be mapped consistently across Northeastern US. The classification was built upon four key attributes: water temperature, trophic state, alkalinity, and depth. Water temperature was mapped into three classes (very cold, cold, and warm-cool) to reflect the requirements and limits of aquatic organisms. Trophic states, representing the productivity of a lake, were mapped into two classes (oligomesotrophic -mesotrophic and eutrophic- hypereutrophic). Alkalinity was grouped into three classes (high, medium, low) to reflect how well the lake system was buffered from acidification. Depth...
