Yayasan Ulin (The Ironwood Foundation) is running a small project to conserve an important wetland habitat in the area of East Kalimantan which is known to contain the crocodiles. Most of them, though, live in Cambodia, where isolated, small groups are present in several remote areas of the Cardamom Mountains, in the southwest of the country, and also in the Virachey National Park, in the northeast of the country.
