A highly permeable landscape promotes resilience by facilitating range shifts and the reorganization of communities. Roads, development, dams, and other structures create resistance that interrupts or redirects movement and, therefore, lowers the permeability. Maintaining a connected landscape is the most widely cited strategy in the scientific literature for building resilience and has been suggested as an explanation for why there were few extinctions during the last period of comparable rapid climate change. This metric is an important component of resilience because it indicates whether a process is likely to be disrupted or how much access a species has to the micro-climates within its given neighborhood. ...

A climate-resilient conservation portfolio includes sites representative of all geophysical settings selected for their landscape diversity and local connectedness. We developed methods to identify such a portfolio. First, we mapped geophysical settings across the entire study area. Second, within each geophysical setting we located sites with diverse topography that were highly connected by natural cover. Third, we compared the identified sites with the current network of conservation lands and with The Nature Conservancy’s (TNC’s) portfolio of important biodiversity sites identified based on rare species and natural community locations.Using this information we noted geophysical settings that were underrepresented...

This broad-scale landscape connectivity dataset identifies areas likely to facilitate ecological flow—particularly movement, dispersal, gene flow, and distributional range shifts for terrestrial plants and animals—over large distances and long time periods. Similar to the local permeability analyses (3km radius, Buttrick et al. 2015), this analysis is not species-specific. Rather, it focuses on structural connectivity of natural lands, with resistance to movement modeled as a function of landscape naturalness. This map does not incorporate projections of future climates, nor does it address connectivity for aquatic species. The results identify broad, intact areas where movement of terrestrial organisms is largely...
Resilience Stratified by Setting and Ecoregion with Regional Override, 2016, Eastern U.S. and Canada

The Nature Conservancy’s Southeast Resilience Project aimed to identify key places areas for conservation based on land characteristics that increase diversity and resilience. This is the estimated resilience score, based on the combined scores of landscape diversity and local connectedness, and ranked relative to the geophysical setting and ecoregion. The estimated resilience score is given as a SD category based on its standard normalized score for the setting and ecoregion. The Resilience Project DOES NOT take into account sea level rise. A climate-resilient conservation portfolio includes sites representative of all geophysical settings selected for their landscape diversity and local connectedness. We developed...
