Bukit Tiban

Bukit Tiban is a national park in Bintulu Division, Sarawak, covering about 80 to 96 sq km^[1]. It encloses the headwaters of the Sungai Nyalau and Sungai Timong in Miri Division and of the Sungai Sigrok, a tributary of the Sungai Similajau in Bintulu Division^[2].

Because most of the surrounding land has been converted to palm oil plantations, the park is an important refuge for remaining wildlife^[1].

The park is an area of inland hill rainforest. Its forest was logged before 1985^[1].

The park lies in the hill country at the headwaters of the Nyalau, Timong and Sigrok rivers^[2].

Bukit Tiban lies in Sarawak's equatorial lowland and hill rainforest zone, which is hot and wet throughout the year.

The forest was logged before 1985, and the surrounding land has since been converted to oil palm plantations^[1].

The park was established in 2000^[1]. Since then much of its eastern half has been converted to palm oil^[1].

The park's defining feature is its river headwaters, which feed the Nyalau, Timong and Sigrok rivers^[2].

The park lies outside Bintulu, the nearest city, which is about 60 km away^[2].

The park is IUCN category II and acts as a refuge in a landscape of plantations. Conversion of its eastern half to oil palm after it was established is a continuing concern^[1].
