Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.  During a study near an ecotourism site, we recorded a melanistic Leopard Panthera pardus delacouri on top of Bukit Kudung in Jeli District.  This finding is considered important because the Indochinese Leopard P.p. delacouri is classified as Critically Endangered in the Red List of Threatened Species by the International Union for Conservation of Nature (IUCN).  We hope that this record will foster conservation efforts in the area.
