Sumatran elephants are Critically Endangered with habitat loss and fragmentation preventing the movements necessary for population viability and individual welfare.
Sumatran elephants living in forest fragments face reduced food availability, increased conflict with human settlements, and the physiological stress of living in constrained, disturbed environments. Corridors that allow movement between forest patches allow elephants to meet nutritional needs over larger areas and find mates. The violence of human-elephant conflict - elephants killed by poison, electrified fences, or gunshot while raiding crops - causes acute suffering at the boundary between elephant needs and human land use.
