Site description (I) Physical CharacteristicsTempasuk Plain is located on the north-west coast of Sabah, stretching from Kota Belud town in the south to Rampayang Laut in the north. The plain is primarily a freshwater wetland bisected by a major road comprising of four main areas;On the eastern side of the road, an area of low wet swamp land with open pools, bordered by a narrow strip of swamp forest along the northern boundary of the Kota Belud Bird Sanctuary (hereafter Bird Sanctuary), and backed by low hills;On the western side, an open sandy foreshore backed by dunes leads into grazed grassland with wet areas and seasonal pools. A small area of mangrove occurs near Kuala Tempasuk;The southern third is taken up with cultivation, mainly wet rice and small settlements. Two large rivers run through the area forming the northern and southern boundaries of the existing Bird Sanctuary. The northern river is lined with fairly extensive riverine forest.The fourth area to the north of Sungai Kawang-Kawang is little known. From Kampung Rampayan Laut for about 5 km upriver mangrove forest predominates (ca. 1,518 ha in 1978), grading into nipa swamp backed by a small area of lowland dipterocarp forest.The Bird Sanctuary was established within the area in 1960, comprising of ca. 12,200 ha. Run-off from the low hills and the foothills of Gunung Kinabalu supplies many small streams and the two large rivers. Grassland floods temporarily, wet rice water levels artificially maintained, swamp probably inundated. The wetland conditions of Tempasuk Plain are determined primarily by local rainfall with the exception of the wet rice fields.(II) Climatic ConditionsAnnual average rainfall is 2,260 mm. Monthly rainfall is between 200-400 mm in June and 100-200 mm in December. The dry season occurs from November-March while the wet from May-September. Annual average temperature range 23-30oC (DWNP, 1987).

Protection status The land tenure is divided up amongst several stakeholders. Grazing Reserve occupies 2,670 ha, Foreshore Reserve, 110 ha and titled land 7,510 ha (either under private ownership or occupied by schools and government agencies). Unallocated land is about 1,740 ha while another 170 ha does not have ownership. Most of the land is either state or titled land. The Kota Belud Bird Sanctuary however was gazetted in 1960, which prohibits hunting within the allotted boundary. The boundary includes the area of low hills to the east but excludes areas of swamp forest and swamp to the north of Sungai Kawang-Kawang. Nevertheless, the protection does not extend to the control of habitat changes.
