Site description
(I) Physical CharacteristicsThe mountain range of Trus Madi follows a major north-east-south-west trend and is strongly dissected into steep sided valleys and narrow-crested ridges. It is separated from Banjaran Crocker by the Tambunan-Keningau-Tenom plain. Banjaran Trus Madi forms the watershed between three of the largest rivers in Sabah State namely the Pagalan, Labuk and Kinabatangan. Gunung Trus Madi (2,642 m asl), the second highest mountain in Sabah State, is located this range. The mountain itself was formed from mudstone, shale and argillite mildly metamorphosed in places to slate with subordinate beds of quartzite, sandstone, siltstone and limestone breccias (Collenette, 1958 cited in Acres, 1972).

Key biodiversity

The highlands is the second most important area for Bornean endemics and montane species after Kinabalu supporting globally threatened birds like the Mountain Serpent-eagle Spilornis kinabaluensis and the Near Threatened Bornean Frogmouth Batrachostomus mixtus (Smythies, 1999).
