Tumbuhan Bawah dan Potensi Jenis Invasif di Gunung Bunder Taman Nasional Gunung Halimun Salak (TNGHS) Bogor

Abstract

Gunung Bunder village is part of Mount Halimun Salak National Park, region II Bogor which some parts of the village used as recreation place and pine tapping area. Both activities cause disturbance and facilitate spreading of potential invasive plants speciesthat can lead extinction of local species and native ecosystem destruction especially ground cover plants. This study aimed to calculate diversity and composition of ground cover plants, and analyze potential invasive ground plant. The study sites were blok Nomer Satu, Sinar Miring, and HM 75. Ten pairs subplots were made alongside the track and field data collected. Data were analyzed by importance value index (IVI), diversity (H’), disperse (E), similarity (IS), and Morisita index. Ground cover plants found were 52 species with highest diversity in Sinar Miring. There were 29 species found in Sinar Miring and 13 of them were ferns. Potential invasive plants found were Digitaria ciliaris, Panicum dichotomiflorum, Clidemia hirta, and Setaria verticillata. These four ground plant grow in clump and disperse randomly. Shrub Clidemia hirta was found in all blok with highest invasiveness potential by average IVI 33.2%.
