Belum-Temengor is the largest continuous forest complex in Peninsular Malaysia. Specifically, it is located in the Malaysian state of Perak and crosses into Southern Thailand. Belum-Temengor is divided into two sections. Belum is located at up north right by the Malaysia-Thailand border while Temengor is south of Belum. The Royal Belum State Park is entirely contained within the forest complex.
Belum-Temengor is believed to have been in existence for over 130 million years making it one of the world’s oldest rainforests, older than both the Amazon and the Congo..[1] In the heart of the forest lies the manmade lake of Tasik Temenggor, covering 15,200 Hectares which is dotted with hundreds of islands.
The area has been identified as an Environmentally Sensitive Area (ESA) Rank 1 under the Malaysian National Physical Plan and recognized by Birdlife International as an Important Bird Area. The Malaysian federal government has labelled the area as a whole as an essential water catchment area and part of Central Forest Spine and plans to protect the forest under the MalaysianNational Forestry Act.
Despite that, between the two, only part of Belum Forest Reserve has been gazette as a State Park while the rest are production forest open for development. Temenggor in particular is facing considerable deforestation due to logging. Environmental organizations such as Malaysian Nature Society and the World Wildlife Fund have been lobbying both the state and the federal government to gazette the area as a park. The state government of Perak however has resisted the effort citing that logging provides the state with more than RM 30 million in revenue. Nevertheless, the state government gazetted 1,175 square kilometres, part of the Belum forest reserve as state park on May 3 2007.
There is a plan to convert natural forest to plantation forest along the East-West Highway.
