Measure habitat connectivity using an accepted tool, according to capacity.

Complete the advanced or basic indicator as follows:

Basic: Calculate effective mesh size, an established measure of fragmentation of natural habitats (see resources below).

Advanced: Calculate the connectivity metric using the “graph theory” framework. Spatial data can be imported into the free Graphab tool to calculate this. Include nearby regional habitat areas if feasible.

Alternative approaches with similar robustness include the Biodispersal plug-in for QGIS, the landscapemetrics R package, or a fragmentation index.
