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).
