Site Description

Mahua is located within the Crocker Range National Park (CRNP) which is on the southern section of the Crocker Mountain Range in Northwest Borneo, Sabah, Malaysia (Isa et al., 2001). A large extent of tropical rainforest highland divides the west coast of Sabah from the remote interior regions of the state. The Crocker Range consists of several rugged and uninhabitable peaks over 1500 m, including Gunung (G) Alab (1964 m), G. Tambuyukon (2579m), G. Trusmadi (2642m) and G. Kinabalu (4218m) (Isa et al., 2001). The rich forest resources that have been most vulnerable to unsustainable exploitation here include both timber and non-timber products. In an effort to conserve the integrity of the forest habitats of Crocker Range, the Sabah State government had declared two National Parks within the range, the Crocker Range National Park (to the southwest) and Kinabalu Park (to the north) (Isa et al., 2001).

Native Forest/Vegetation Types

Vegetation type is tropical lower montane forest. Research by Ipor et al. (1999) showed that the vegetation at Mahua MDF exhibit moderate diversity of tree species despite having high density of plants. The species composition is considered moderately diverse, dominated by Duabanga moluccana. Other co-dominant species are Knema ashtonii, Agathis lanceolata, Lithocarpus cantleyanus and Litsea ochracca. Other less dominant species are Xanthophyllum schizocarpum, Baringtonia sarcostachys, Shorea maxwelliana, Alseodaphne insignis, Litsea resinosa, Beilsmedia pauciflora, Alseodaphne foxiana, Endiandra kingiana and Litsea machilifolia.
