STATUS POPULASI DAN KONDISI HABITAT SURILI {Presbytis comatd) DI CAGAR ALAM SITU PATENGAN, JAWA BARAT

Abstract

Population and habitat survey was conducted in June-July 2000, at Situ Patengan Nature reserve, which aimed to record the current population data and habitat conditions. We recorded seven groups of grizzled leaf monkey/surili occurred at nature reserve, with number of 3 individual were vary between 4-8 individual each group and population density of 17/km . Sex ratio of individuals were 1:1.86, with percentage of age structures consisted of 17.95% adult male, 33.33% adult female, 25.64% juvenile, 20.51% offspring and 2.56% infant. Vegetation analysis recorded 56 species of plants found in the reserve. Some of the species were dominance, i.e. pasang (Quercus sp.), kihiur {Castanopsis javanica) and puspa {Schima walichii). Since population survey were conducted by Ruhiyat (1983) with population 2 3 density of 35 individuals/km and Adriana (1995) with population density of 3.5 individuals/km , the population density of the monkeys shown trend of decreasing. The reserve, located adjacent with some plantation areas and production forest area of Perum Perhutani, isolated the forest. This condition predicted as a potential threat to the habitat and population of the monkeys. The monkey's population will be a doomed population in the future.
