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...

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a collaborative framework for taking on the critical task of assessing and upgrading the hundreds of thousands of outdated road-stream crossings across the region that represent barriers to wildlife movement and pose flooding risks to communities.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...

Consistent and accurate landscape datasets are important foundational products for ecological analyses and for understanding and anticipating the effects of climate change on forested, agricultural, and freshwater systems across the U.S. and Canada. The objective of this project was to extend an existing terrestrial habitat map of the north Atlantic U.S. to Atlantic Canada and southern Quebec, using and modeling field-collected data combined with national and provincial datasets. This GIS map 1) provides a foundation upon which further research, such as species vulnerability analyses, can advance, 2) allows each relevant state and province to identify terrestrial habitats consistently across borders, 3) allows for...
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...
With support from the North Atlantic LCC and Hurricane Sandy Disaster Mitigation funds the North Atlantic Aquatic Connectivity Collaborative (www.streamcontinuity.org) has developed a regional crossing assessment protocol and database, scoring systems for aquatic organism passage, and hydraulic risk of failure assessments based on future storm discharge levels. The existing NAACC protocol was developed primarily for freshwater streams and the suite of organisms that occur in these systems. There is strong interest among conservation practitioners to have a method to assess tidally influenced crossings for their potential as barriers to aquatic organism passage. Protocols designed for freshwater streams will not...
Sea levels are expected to rise by one to six feet over the next century, and coastal sites vary markedly in their ability to accommodate such inundation. In response to this threat, scientists from The Nature Conservancy evaluated 10,736 sites in the Northeast and Mid-Atlantic for the size, configuration and adequacy of their migration space, and for the natural processes necessary to support the migration of coastal habitats in response to sea-level rise. The resulting resilience dataset is intended to help natural resource managers, conservationists, and others identify resilient lands for protection and restoration across the North Atlantic coast, and has been integrated into the Nature’s Network conservation...

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...

Landscape permeability is the ability of a land area to allow organisms to move and disperse, equivalent to what some authors call “habitat connectivity.” This project evaluated and mapped the relative landscape permeability for terrestrial organisms across the eastern United States and southeastern Canada, taking into account features that impede natural connectivity such as roads and other development. The analysis assigned locations to categories of diffuse flow (intact, permeable areas that facilitate high levels of dispersal), concentrated flow (large quantities of flow are concentrated through a narrow area), constrained flow (low permeability, with flow following a weak reticulated network), or blocked flow...

The presence of salt water is an important determinant of ecological communities. This dataset modifies the Northeast Terrestrial Habitat Map (linked below), developed by The Nature Conservancy, to denote the presence of salt water or brackish water as follows: -Wetlands and waters classified by the National Wetland Inventory (http://www.fws.gov/wetlands/) as "marine", plus additional ocean waters to a distance from the coast of 10 km, are considered salt water and assigned a value of "1" -Wetlands and waters classified by the National Wetland Inventory as "upper estuarine" are considered oligohaline and assigned a value of "0.5" -Wetlands and waters classified by the National Wetland Inventory as "estuarine" are...
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...
