Jaguar Corridors

Land cover, percent vegetative cover, elevation, human population density, distance from settlements and distance from roads were used as input layers. The layers were standardized to a 1 square kilomter resolution. Experts from throughout jaguar range provided movement costs to each one of these layers on a scale from 0 (no movement cost) to 10 (a very high movement cost). These costs were applied to the layers and the layers were added together on a pixel by pixel basis to create a movement cost surface. Any value over 25 was considered a barrier to movement. Cost Distances were calculated from each of the 90 known jaguar populations and then least-cost corridors were modeled. The corridors in this shape file represent the lowest 0.01% of corridor values.
