Ulu Muda Forest
The Greater Ulu Muda Forest Complex (GUMFC) is a large expanse of lowland dipterocarp forest in the north of Kedah State, Malaysia, on the border with Thailand. The area has high biodiversity thanks to relatively low rates of poaching and human intrusion. A number of endangered species are known to be present in the GUMFC. The forest is in the Peninsular Malaysian rain forests ecoregion. The water that it provides through the man-made Muda, Pedu and Ahning lakes provide water to the Muda agricultural area as well as much of Kedah, Penang and Perlis. The forest  has been both selectively and illegally logged in the past, possibly causing excess sedimentation of the water courses, and the future of the forest remains uncertain. The majority of the forest is not very accessible, the easiest point of entry being the KOPAM jetty on Muda Lake. Ulu Muda Wildlife Reserve covers an area of 1152.57 km². The reserve adjoins San Kala Khiri National Park in Thailand.
