• The Sumatran Tiger (Panthera tigris sumatrae) is critically endangered according to the IUCN (International Union for the Conservation of Nature), with approximately 400-500 individuals surviving in the wild, and is the last surviving subspecies of tiger in Indonesia.
• Primary threats to the Sumatran tiger include habitat loss, poaching for the illegal trade in skins and traditional medicines, decline in prey species due to hunting, the limited extent and high fragmentation of protected areas, and often fatal conflict with humans.
• The Sumatran Tiger Conservation Program is a collaborative program of the Indonesian Directorate General of Forest Protection and Nature Conservation, Ministry of Forestry, the Sumatran Tiger Trust of the UK and The Tiger Foundation of Canada. Its focus is intensive anti-poaching patrols, illegal trade investigation, remote camera monitoring of tigers and their prey, management support of priority national parks, national policy development, public awareness and on-the-ground facilitation of locally initiated tiger conservation efforts.
• The Sumatran Tiger Trust, British registered charity No. 1082186, has supported conservation activities in Sumatra since 1996. With 0% overhead and a volunteer staff, it seeks to maximise its resources in working with Indonesian authorities to implement creative and bold measures to conserve Sumatran tigers in the wild. STT has been the primary source of funding for the program since 2002.
• The Tiger Foundation is a Canadian, 100% volunteer-staffed conservation group exclusively devoted to the preservation of wild tigers. It supported the Sumatran Tiger Conservation Program and predecessor project between 1996 and 2002, and has also been active in combating tiger poaching and habitat loss in India since 2000.
• The Save The Tiger Fund is an ExxonMobil sponsored grant-awarding body, administered by the National Fish and Wildlife Foundation (USA), providing support for tiger conservation efforts around the world.
