Struktur dan Komposisi Tumbuhan Bawah di Zona Pegunungan Bawah Blok Malagembol, Cagar Alam Gunung Tilu, Jawa Barat

The understorey is one type of tropical forest vegetation that contributes to the complexity structure. habitat closely related condition vegetation. This study aims determine structure and composition support ecological function in Malagembol Block, Mount Tilu Nature Reserve. sample collection was carried out using plot method. A total three main plots measuring 10×100 m2 were divided into ten subplots with a size 5×5 m2. observed included herbaceous plants saplings height less than 1 m. data analysis calculation frequency, density, individual dominance, significant value index heterogeneity (Shannon-Wiener), richness (Margalef), evenness index. 186 species 66 families recorded observation plots. Based on their stature, they grouped 26 climbing plants, 43 116 saplings. high more diverse. In addition, found evenly distributed each plant community relatively stable. Reserve has an important contribution compiling ecosystem so it becomes further consideration for management area around
