Abstract

We present the first population estimate for the Natuna leaf monkey Presbytis natunae, endemic to the island of Bunguran, Indonesia, based on a 2-month survey. Bunguran has a land area of only 1,605 km(2) and was until 1980 largely covered in primary forest. At present primary forest exists only in small patches within a matrix of logged forest, which covers nearly 70% of the island. Natuna leaf monkeys are confined to forest and have a preference for primary lowland forest patches. Groups average 3.5+/-SD 2.0 individuals and occur in a density of 2.3+/-SD 1.1 groups per km(2). Extrapolation of the density estimates to the entire island indicates that
