Site description (I) Physical CharacteristicsThe Klias Peninsula is located on the coast of south-western Sabah, forming the north-eastern shore of Brunei Bay, the south-western shore of Kimanis Bay and bounded on the inland side by Banjaran Crocker and on the western side by a ridge on a higher ground. Four major natural vegetation types occur in the area namely mangrove forest in coastal area, nipa swamp, freshwater swamp forest and peat swamp forest. Much grassland, scrub and other secondary growth occur throughout the peninsula (DWNP, 1987; Scott, 1989; Wells et al., 1975).(II) Climatic ConditionsOne of the heaviest rainfall sites in Sabah, annual average ca. 3,680 mm (at Weston), fairly evenly distributed with a low in February and a high in November. Annual average temperatures vary from 25-31oC (DWNP, 1987).

Other biodiversity A scientific survey was conducted in two peatswamp Forest Reserves, the Binsulok and Klias Forest Reserves, in 1999 which yielded several interesting findings on flora and fauna.One hundred and thirty-four species from 59 families of trees were recorded, which were dominated by Dryobalanops rappa, Stemonurus scropioides, Palaquium rostratum, Gonystylus bancanus and Combretocarpus rotundatus (Berhaman Ahmad and John Baptist Sugau, 2000). Four species of Nepenthes namely N. ampullaria, N. bicalcarata, N. gracilis and N. rafflesiana were recorded (Takahashi and Berhaman Ahmad, 2000).Sixty-six butterfly species from 42 genera were discovered including two uncommon species, Thaumantis klugius and T. nouredin, which are restricted to dark forest understorey (Mohd. Fairus Jalil et al., 2000). Twenty-three species of fishes were collected from salt and freshwater sources (Mohd. Nadzri Ishak et al., 2000).Five species of amphibians, Hoplobathracus rogulosa, Rana erythraea, R. glandulosa, Polypedates coletti and P. leucomystax, were recorded (Ahmad Sudin and Maryati Mohamed, 2000).Four species of small mammals were recorded (Shigeki et al., 2000). Presence of Estuarine Crocodiles Crocodylus porosus (Stuebing et al., 1992, 1994). (I) Globally threatened mammals (IUCN, 2002): ENDANGERED: Proboscis Monkey Nasalis larvatus; VULNERABLE: Pig-tailed Macaque Macaca nemestrina; NEAR THREATENED: Long-tailed Macaque M. fascicularis, Pangolin Manis javanica, Oriental Small-clawed Otter Amblonyx cinereus; DATA DEFICIENT: Malayan Sun Bear Helarctos malayanus(II) Globally threatened reptiles (IUCN, 2002): ENDANGERED: Green Turtle Chelonia mydas; VULNERABLE: Asiatic Softshell Turtle Amyda cartilaginea(III) Globally threatened plants (IUCN, 2002): CRITICAL: Hopea pentanervia, Shorea platycarpa; ENDANGERED: Shorea teysmanniana; VULNERABLE: Combretocarpus rotundatus, Calophyllum havilandii, Gonystylus bancanus, Nepenthes bicalcarata

Protection status Some 31,053 ha are state-owned in five Forest Reserves (Sungai Binsulok, Klias, Padas Damit, Kampung Hindian and Menumbok) while the remainder of the region is either Stateland or privately owned. In 1978, 30,900 ha of the coastal parts the Klias Peninsula were gazetted as a National Park but was degazetted in 1980 (DWNP, 1987). It is the last remaining major peat swamp forest in Sabah. Both are Class 1 Forest Reserves, which prohibits logging (Maryati Mohamed et al., 1999).
