To create a wall-to-wall surface of landscape permeability we used the software CIRCUITSCAPE (McRae and Shah 2009), an innovative program that models species and population movements as if they were electric current flowing through a landscape of variable resistance. Circuit modeling is conceptually aligned with the concept of landscape permeability because it recognizes that movement through a landscape is affected by a variety of impediments, and it quantifies the degree and the directional outcomes of the compounding effects. One output is a “flow” map that shows the behavior of directional flows and highlights concentration areas and pinch-points.The results can highlight locally and regionally significant places...

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 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.
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...

Resilience concerns the ability of a living system to adjust to climate change, moderate potential damages, take advantage of opportunities, or cope with consequences; in short, the capacity to adapt. The Nature Conservancy’s resilience analysis develops an approach to conserve biological diversity while allowing species and communities to rearrange in response to a continually changing climate. - See more at: http://nature.org/TNCResilience Eastern Division scientists analyzed 393 million acres of land for resilience, stretching from Florida to Maine and adjacent areas of Canada (NOTE - The dataset included in the download was clipped to the Northeast (Region 5), for the original data see: https://nalcc.databasin.org/datasets/c57ec56be4524d81af3491747c865d29)....
Numerous studies show that ongoing climate change will have major effects on the distribution and conservation status of much of our biodiversity. Resource managers urgently need a means to identify which species and habitats are most vulnerable to decline in order to direct resources where they will be most effective. To address this need, NatureServe and Heritage Program collaborators have developed a Climate Change Vulnerability Index (CCVI) to provide a rapid, scientifically defensible assessment of species’ vulnerability to climate change. The CCVI integrates information about exposure to altered climates and species-specific sensitivity factors known to be associated with vulnerability to climate change. This...

This report describes an effort of a team of 60 scientists led by The Nature Conservancy (TNC) to identify the places where nature’s own natural resilience is the highest. Thanks to the land’s diverse topography, bedrock, and soil, these climate-resilient sites are more likely to sustain native plants, animals, and natural processes into the future, becoming natural strongholds for diversity. To map their locations, The Nature Conservancy-led team used over 70 new and comprehensive datasets to find places that are buffered from the effects of climate change because the site offers a wide range of micro-climates within a highly connected area. In 2015, the results were published in a leading conservation science...
This project built off a first phase of work funded by Northeast states through the Regional Conservation Needs program by assessing the vulnerability to climate change of 7-10 additional northeastern habitat types, including forests, wetlands, and aquatic systems. Tidally-influenced habitat vulnerability was also assessed and included development of a database of ongoing coastal climate change projects and tools.The project will also build capacity in the Northeastern states for Regional Vulnerability Assessments and will coordinate with NOAA in the development of an on-line catalog of coastal climate change assessments.
