History The first scientific study of the area was conducted in 1892 by H.W. Lake and Lieutenant H.J. Kelsall. With the aid of the study, the forest complex of Endau-Kluang was gazetted as a forest reserve in 1933. Later in 1972, the forest reserve was expanded to include Lesong forest reserve in Pahang. In the same year, the federal government came up with a proposal to federally protect 2,000 km² of the complex as a national park. At that time there was no legal mechanism to create a national park. In 1980, the National Parks Act 1980 (Malaysia) was passed by the Malaysian Parliament. However, dispute between federal and state powers prevented the creation of a national park in the area at that time. Five years later, the Department of Wildlife and National Parks proposed roughly the same areas to be gazetted as wildlife sanctuary to protect the critically endangered Sumatran rhinoceros. In 2022, Endau-Rompin National Park was declared an ASEAN heritage park.
