Abstract

Surili play an important role in the ecosystem, especially in the preservation and dispersal of seeds, and ensuring that the ecosystem remains balanced. Not many studies have been conducted on the various plant species consumed by surili in various areas of TNGGP. The purpose of this study is expected to provide very important information to support surili conservation plans and habitat management. This study was conducted in two resorts in the division I Cianjur of TNGGP: Tegallega Resort and Sarongge Resort. The study took place from March 2023 to August 2024. Data were collected by directly observing surili feeding activities in eight transects, each 2.5 to 3 km long, for 16 months. The types of plants eaten and the parts eaten. The data collected were recorded and analyzed descriptively. Surili results showed that there were 11 species of food plants in Tegallega Resort and 7 species in Sarongge Resort. However, three species were dominant in both resorts: Castanopsis argentea, Liquidambar excelsa, and Schima wallichii. Surili in Tegallega Resort ate leaves 78.57%, fruits 14.29%, and flowers 7.14%, while surili in Sarongge Resort only ate leaves (100%).
