Sumatran rhino (Dicerorhinussumatrensis) is the smallest and most primitiveof all extant rhino species in the world, with distinct appearance from the other rhino – hair covers most of their body. This large mammal can grow up to 1.5 m high & 3m long, and weigh about 800 kg. Sumatran rhino has two horns and can live up to 40 years old. They once ranged from northeast India to Indonesian Borneo and may have numbered in the tens of thousands. Today, much has changed for the Sumatran rhino. It's one of the most endangered large mammals on the planet. They are listed on the IUCN Red List as critically endangered and world population estimates since 1985 show a precipitous fall. Most recently, it has been estimated that there are less than 100 individuals left in the world. What we do?- Supporting the Indonesian Government Rhino Secretariat to take high-level action to save Sumatran rhinos.- Supporting Bukit Barisan Selatan National Park, the location of one of the four Sumatran rhino populations in Indonesia, in establishing an "Intensive Protection Zone" for the remaining rhinos in the park.- Setting up Resort Based Management patrol system using SMART in Bukit Barisan Selatan, Gunung Leuser, and Way Kambas National Park, three priority areas for Sumatran rhinos, to enhance the overall protection effort of the species by government.- Conduct scientific research on rhino to improve conservation strategies: Conducted an island wide scale of occupancy survey to better targeting their protection effort, and helping the Gunung Leuser NP in conducting population survey using camera-traps and DNA.
