Cát Tiên National Park (CTNP) was protected initially in 1978 as two sectors, Nam Cat Tien and Tay Cat Tien. Another sector, Cat Loc, was gazetted as a rhinoceros reserve in 1992 upon the discovery of a population of the Vietnamese Javan rhinoceros, an occasion that brought the park into the world's eye. The three areas were combined to form one park in 1998. Nam Cat Tien is contiguous with Vĩnh Cửu nature reserve thus providing an enlarged area for species to breed. The forest is now protected by the "Kiểm lâm" (VN Forest Rangers) with responsibilities for managing poaching, fire control, and other issues.
