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a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings across the region that represent barriers to wildlife movement and pose flooding risks to communities.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 Interactive Catchment Explorer (ICE) is a dynamic visualization interface for exploring catchment characteristics and environmental model predictions. ICE was created for resource managers and researchers to explore complex, multivariate environmental datasets and model results, to identify spatial patterns related to ecological conditions, and to prioritize locations for restoration or further study. ICE incorporates stream temperature and brook trout occurrence models for headwaters of the Northeast, including projections of the potential effects of climate change. ICE is part of the Spatial Hydro-Ecological Decision System (SHEDS).

Boston, MA.The aquatic habitat guides are a companion to the Northeast Lake and Pond Classification (Olivero and Anderson, 2016; available at http://nature.ly/NElakes) and is an addition to the Northeast Habitat Guides: A Companion to the Terrestrial and Aquatic Habitat Maps (Anderson et al. 2013).The guides provide users with a compact fact sheet describing each of the mapped habitats, and providing information on the ecology and conservation status of the habitat, including: Map of the regional distribution Photos of example habitat Description...
This tool allows users to view aquatic barriers (dams, road-stream crossings) by the relative gain in ecological value if they were removed. Users start with a consensus map of anadromous fish priorities, which was developed based on stakeholder input as part of the North Atlantic Aquatic Connectivity Collaborative (NAACC). Beyond the consensus results, interested users can create their own scenarios by filtering input barriers to limit the analysis to a given state or watershed, changing the weights of metrics according to their importance to the analysis objectives (e.g. length of upstream network connected, number of diadromous fish present, etc.) and by modeling the removal of up to 10 barriers.The link address...
Citation: Olivero-Sheldon, A. and M.G. Anderson. 2016. Northeast Lake and Pond Classification. The Nature Conservancy, Eastern Conservation Science, Eastern Regional Office. Boston, MA.AbstractWe developed a mapped classification of lakes and ponds based on facors that structure lacustrine ecosystems and that could be mapped consistently across Northeastern US. The classification was based upon four key variables: water temperature, alkalinity, trophic state, and depth. Water temperature was mapped into three classes (very cold, cold, and cool-warm) to reflect the requirements and limits of aquatic organisms. Alkalinity was grouped into three classes (high, medium, low) to reflect how well the lake system was buffered...

To effectively manage vital freshwater resources across large geographic areas, resource managers need the capacity to assess the status of aquatic species, their habitats, and the threats they face. This on-line decision support tool provides that capability for Eastern brook trout across the Chesapeake Bay watershed. The tool allows users to characterize current and and potential future aquatic conditions, target and prescribe restoration and conservation actions, set strategic priorities, evaluate management efforts, and support science-based sustainable management plans on behalf of brook trout and associated species. The tool is accompanied by a user-friendly summary report and a technical report providing...
