Description: This analysis represents a wall-to-wall picture of regional habitat connectivity for plant and animal species whose movement is inhibited by developed or agricultural land uses. The approach treats landscapes as resistive surfaces, where high-quality movement habitat has low resistance and barriers have high resistance. The algorithm incorporates all possible pathways between movement sources and destinations and identifies areas of high flow via low-resistance routes, i.e., routes presenting relatively low movement difficulty because of lower human modification, and thus mortality risk.
