The regional conductance index is a measure of the total amount of movement of plants and animals that has the potential to pass through a cell from nearby terrestrial core areas. The scale at which this is measured is a few to ten kilometers. Areas close to many large cores and passing through natural areas of similar type will have high regional conductance values, reflecting the likelihood that large amounts of plants and animals are nearby and thus likely to pass through a particular cell. Regional conductance would be further increased if the nearby large cores are made up of similar ecological system types, since this would facilitate movement by species targeting certain habitats. Regional conductance is best used to measure connectivity between core areas (in contrast to local conductance, which is better suited to measure connectivity within core areas).
