Sumatran orangutans survive in increasingly fragmented forest patches, and corridor protection is essential for population viability.
Orangutans in isolated forest patches face nutritional stress from limited food tree diversity, inbreeding from small population size, and increased exposure to human conflict. Individuals crossing through degraded corridors are vulnerable to snaring, shooting, and electrocution on agricultural fencing. Maintaining and improving forest corridors directly protects individual orangutan safety and population genetic health.
