THE Ulu Muda Rainforest is a natural heritage of 150 -170 million years rainforest located at the north-eastern corner of the state of Kedah, bordering Thailand. The size of the Ulu Muda Rainforest is about twice the size of Singapore. It encompasses the Ulu Muda Forest Reserve and Pedu Forest Reserve and is also where three important lakes and dams are - Pedu Dam, Muda Dam and Ahning Dam.
These three dams are responsible for providing irrigation to increase paddy production for the needs of the country. Ulu Muda Rainforest used to have high biodiversity and consists of high-quality logs such as meranti, cengal and merbau due to low rates of poaching and human intrusion.
