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...

Fresh and Saltwater Connectivity This layer was one of the old South Atlantic LCC indicators in the waterscapes ecosystem. It was an index of dams preventing fish migration between rivers and the ocean. Fresh and saltwater connectivity was not performing well as an indicator and could not be used in Blueprint 2.0. This indicator was replaced in Blueprint 2.1 with a new migratory fish connectivity indicator. Reason for Selection Barriers to connectivity between rivers/streams and the ocean can strongly impact diadromous fish and alter natural movement of sediments, are easy to monitor and model, and are widely used and understood by diverse partners.

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...

Index of fresh and saltwater connectivity This layer is one of the South Atlantic LCC indicators in the waterscapes ecosystem. To read more about the indicators and how they are being used, please visit the indicator page. Reason for selection Barriers to connectivity between rivers/streams and the ocean can strongly impact diadromous fish and alter natural movement of sediments, are easy to monitor and model, and are widely used and understood by diverse partners. Input Data Southeast Aquatic Connectivity Assessment Project: This project, a collaboration between The Nature Conservancy, the Southeast Aquatic Resources Partnership, and the South Atlantic LCC, identifies opportunities to improve aquatic connectivity...

Resilience concerns the ability of a living system to adjust to climate change, to moderate potential damages, to take advantage of opportunities, or to cope with consequences; in short, its capacity to adapt. In this project we aim to identify the most resilient examples of key geophysical settings (e.g. sand plains, granite mountains, limestone valleys, etc.) in New york State to provide conservationists with a nuanced picture of the places where conservation is most likely to succeed over centuries.The project had three parts: 1) identifying and mapping the geophysical settings, 2) developing a quantitative estimate of resilience for each setting based on landscape complexity and permeability, and 3) identifying...

This presentation is part of the Decision Support Tools for Natural Resource Managers in Sagebrush Communities and Across the Pacific Northwest Workshop Series, funded by the Great Basin Landscape Conservation Cooperative (LCC). Mike Gough with Conservation Biology Institute provides a rapid overview of the Sagebrush Climate Console. He demonstrates the new Nature’s Stage Climate Mapper. The objective of this session to show participants possible applications they can use in management decision-making.
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...

This data product was created for the project titled: “Application of the Coastal and Marine Ecological Classification Standard (CMECS) to the Northwest Atlantic” which was partially funded by the U.S. Department of the Interior, Fish and Wildlife Service and a joint collaborative project with The Nature Conservancy (Eastern Division Conservation Science), University of Rhode Island (Graduate School of Oceanography), and Massachusetts Department of Fish and Game (Division of Marine Fisheries). In the Northeast United States region, efforts are underway to better organize and integrate spatial marine data to support ocean planning and management efforts. An important step in this process is translating existing...
