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. ...

The local connectedness dataset measures how impaired the structural connections are between natural ecosystems within a local landscape. Roads, development, noise, exposed areas, dams, and other structures all directly alter processes and create resistance to species movement by increasing the risk (or perceived risk) of harm. This dataset 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 microclimates within its given neighborhood. The method used to map local connectedness for the region was resistant kernel analysis, developed and run by Brad Compton using software developed by the UMASS CAPS program (Compton et al....

The data layer represents a potential Conservation Target (CT) for PFLCC's Connectivity Priority Resource(PR). The potential Conservation Target is the quality of the connections of the PR. The analysis on the Connectivity Priority Resource was performed using the Local Connectedness core layer of the Nature Conservancy's Resiliency Project. The Local Connectedness is an evaluation of the Land Use and Roads around each pixel to determine the resistance to movement of microhabitats across the landscape in the advent of local climate change. Reported metrics, however, reflect the opposite of resistance, instead the permeability of the landscape and are reported as Z-scores around the regional mean index value. ...
