Summary

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 where species [...]

Purpose

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. Scientists considered individual landscapes such as forests, wetlands, and mountain ranges as collections of neighborhoods where plants and animals reside. Areas with the most complex neighborhoods in terms of topography, elevation ranges, and wetland density were estimated to offer the greatest potential for plant and animal species to “move down the block” and find new homes as climate change alters their traditional neighborhoods. The resilience study also considered the permeability of landscapes, analyzing where roads, dams, development, or other fragmenting features create barriers that prevent plants and animals from moving into new neighborhoods. Together, the diversity of physical features and the ability for local movement define a landscape’s resiliency.
