Husodo T, Santoso P, Partasasmita R, Hendrawan R. 2015. Community structure and plant tipology in the Nature Recreational Park and Nature Reserve Pananjung Pangandaran, Pangandaran District, West Java. Pros Sem Nas Masy Biodiv Indon 1: 647-654. The research on the plant community structure in Pananjung Pangandaran Nature Recreational Park and Nature Reserves (TWA & CAPP) have been conducted since 1980 by various researchers, but the research of the typology of plant community has never been done. Based on this, the research on the typology of plant community in the TWA & CAPP was conducted. This research was conducted between May and August 2014. The methodology used was a qualitative and quantitative method, through literature studies and field surveys. Referring to the literature study, there were nine locations which have always been the object of research, namely Cirengganis (Nature Recreational Park) dan Tadah Angin, Nanggorak, Badeto, Cimanggu, Karang Pandan, Raja Mantri, Batu Meja, dan Cikamal Ecoton (Nature Reserves). Based on the analysis, there were 133 plant species (53 families) with vegetation type of tree (46 species), pole (61 species); shrub (73 species); seedling and grass (95 species). Similarity index (Sorensen 1974) of the location which had similar vegetation structure was Batu Meja and Rajamantri (ISs = 54.79), whereas the location which had smallest similarity value was Cirengganis and Batu Meja (ISs= 0). The location which had the highest diversity index value of Shannon-Wiener (Muller-Dumbois and Ellenberg 1974) from 9 locations was Tadah Angin (H’ =3.69) and the lowest was Karang Pandan (H’=2,05). In a comparison of Distribution Pattern Index (Morisita 1965 in Krebs 1972), recorded 130 species of plants was distributed clumped, and the other three species was distributed evenly. In typology of plant community that analyzed by NTSYSpc 2.02i, there was two type of plant community, namely lowland forest plants community type that has a specification like riparian vegetation (Tadah Angin) and transition areas between grassland and lowland forest (Cikamal Ecotone). Besides, typology of plant communities in the TWA & CA PP was coastal vegetation (Cimanggu and Karang Pandan), lowland forests (Nanggorak, Cirengganis and Badeto), mixed forests/coastal vegetation and lowland forests (Batu Meja and Raja Mantri). |
