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...

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.

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)....
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...

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...
