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.
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...

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...
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...

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...
