This dataset contains measures of seasonal mean bird stopover densities and in seasonal mean bird density based on weather surveillance radar data from 20 radar locations in the Northeast U.S. across seven autumn migrations (15 August through 7 November of 2008-2014) [six autumn migrations for the terminal doppler weather radar (15 August through 7 November of 2009-2014)]. Data are present only in radar-sampled areas for each individual radar (see below for description on how these data are filtered). If you are interested in a continuous map of bird stopover densities for the entire region (and outside of these radar coverage areas), refer to layer “Predicted autumn migratory landbird density, 1km, Northeast U.S.”.The...

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...
Publication from the NALCC co-funded project Identifying Important Migratory Landbird Stopover Sites in the Northeast. With many of the world’s migratory bird populations in alarming decline, broad‐scale assessments of responses to migratory hazards may prove crucial to successful conservation efforts. Most birds migrate at night through increasingly light‐polluted skies. Bright light sources can attract airborne migrants and lead to collisions with structures, but might also influence selection of migratory stopover habitat and thereby acquisition of food resources. We demonstrate, using multi‐year weather radar measurements of nocturnal migrants across the northeastern U.S., that autumnal migrant stopover density...
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...

Stream fish data providers for 2015 national assessment of stream fish habitats.
This report describes the results of efforts by the Maryland Department of Natural Resources Monitoring and Non-Tidal Assessment Division to monitor and assess ecological changes in the Patapsco River associated with the removal of Simkins and Union Dams. There are six aspects of the Patapsco River’s ecosystem that were examined: anadromous fish, American eels, resident fish, benthic macroinvertebrates, freshwater mussels, and water quality. Each of these aspects is described in a separate chapter that includes a brief review of literature followed by a discussion of results from Patapsco monitoring. Prior to these chapters is an Introduction that describes the river and its dams. There is an Ecological Monitoring...

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.
Final Report of the NALCC funded project “Identifying Important Migratory Landbird Stopover Sites in the Northeast”.The national network of weather surveillance radars (NEXRAD) detects birds in flight,and has proven to be a useful remote-sensing tool for ornithological study. We used datacollected during Fall 2008 to 2014 by 16 NEXRAD and four terminal Doppler weather radars(TDWR) in the northeastern U.S. to map and study the spatial distribution of landbirds shortlyafter they leave daytime stopover sites to embark on nocturnal migratory flights. Given observedvariability in the precise timing of migratory exodus, we developed a new method to sample theonset of migration at the point of maximum rate of increase...

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...

This dataset represents the observed and predicted relative bird density during autumn migratory stopover within the Northeast and Mid-Atlantic U.S. as measured by NEXRAD weather surveillance radar during the periods of peak landbird migration (15 August to 7 November) during 2008 through 2014. The dataset also includes measures of land cover characteristics, vegetative productivity, and geographic context used in the models to predict bird stopover use. Observed data are present only in radar-sampled areas (see below for description on how these data are filtered) while predicted data are modeled across the entire Northeast U.S. The dataset was originally developed as supplemental information for the cooperative...

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...

Dozens of species of landbirds, such as warblers, hummingbirds, and orioles, migrate through the Northeastern United States from their summer breeding grounds in the U.S. and Canada to their nonbreeding grounds as far south as South America. During the migration period, birds must find habitat where they can stop, rest and replenish their energy reserves. Conservation efforts are increasingly focused on identifying stopover sites that are important for sustaining migratory landbird populations. This project builds upon prior work by the University of Delaware and USGS to use weather surveillance data and field surveys to map and predict important migratory bird stopover sites.This project was co-funded by through...
