Tabin has been declared a wildlife reserve primarily on account of the large number of animals inhabiting its forests, some of which are highly endangered. The three largest mammals of Sabah – the
Borneo elephant,
Bornean rhinoceros (a subspecies of the
Sumatran rhinoceros) and
tembadau (
Bos javanicus), are all found within the reserve. The elephant population has been estimated to 120-300 animals in 1993. Other ungulate species include
sambar,
muntjac and
mouse deer. In addition seven of Sabah's eight primate species are present, among them
orangutan and
proboscis monkey. However, these two species occur in relatively low numbers in the reserve. The biggest predator in the reserve is the
Sunda clouded leopard. There are also several other smaller carnivores in the reserve. Of bird species, 42 families representing 220 species have been recorded. == Organisation ==
