Ficus heteropleura, a common Borneo endemic fig of wet hill forest photographed at  500m on Bukit Silam. Bukit Silam  is formed of ultrabasic soils with a high content of nickel and manganese resulting in a very specialized flora. In general the Ficus flora on ultramafic soils is much reduced compared with normal soils in Sabah and comprises a subset of the most common fig  species with a couple of interesting exceptions. See Ficus tarrenifolia

Map Gunung Silam ENHANCED.jpg
Bukit Silam is approx. 882 m high and due to the Massenerhebung effect has an area of stunted forest on the summit, normally only present on mountains over 2000m.  The  Chestnut-crested Yuhina Yuhina  everetti normally only found on mountains in Borneo is present in the summit area. There is a 9 km road from the entrance gate to the Telecom Tower at approx. 700m  where there is a viewing tower which overlooks the scenic islands in Darvel Bay. See this link
Gunung Silam on East Sabah map.jpg
Bukit Silam is an isolated hill  with ultramafic soils high in manganese and nickel  next to the coast in east Sabah. The ultramafic soil means that Bukit Silam is not suitable for agriculture and most of the unique forest is protected as a water catchment. Gunung Silam is  around  20 minutes drive from the town of Lahad Datu in East Sabah. See the yellow circle on the map
