Forest corridors connecting fragmented primate habitat allow population mixing, gene flow, and seasonal resource access that isolated forest patches cannot provide — improving welfare at individual and population levels.
Primate welfare in fragmented landscapes is inseparable from landscape connectivity. Individual primates confined to isolated forest patches experience nutritional stress from limited dietary diversity, behavioral restriction from reduced ranging space, and reproductive failure from inbreeding. Corridor provision — whether through forest protection, restoration, or shade agriculture — directly expands the welfare opportunities available to primate populations. Individual animals that can move seasonally between patches have access to diverse food resources, social partners, and the behavioral complexity that their intelligence requires. Corridor investment is a welfare investment for every individual in the connected population.
