The main threat to the survival of primates in Sumatra is habitat destruction, but there is also an increasing problem of conflict with local people due to crop-raiding. This study characterizes the perceived impacts of primate crop-raiding in four villages in North Sumatra. Ninety-eight semi-structured interviews were conducted to collect data on (i) crop species, (ii) which vertebrates are thought to damage crops, (iii) the perceived extent to which each vertebrate species damages crops, and (iv) the preventive measures taken in the four villages.
