Abstract

Purnomo XK, Yusniawati Y, Putrika A, Handayani W, Yasman. 2017. Seagrass species diversity at various seagrass bed ecosystems in the West Bali National Park Area. Pros Sem Nas Masy Biodiv Indon 3: 236-240. The coastal area overgrown with seagrass known as seagrass bed and are a unique ecosystem. There are about 60 species of seagrasses worldwide which are 12 of them found in Indonesia. West Bali National Park (TNBB) is one of many areas in Indonesia where seagrass ecosystems are found. The research was to survey abiotic factors, diversity, frequency, the relative frequency and the species composition of seagrass at the various coast in TNBB. This information hopefully will help possible repeated monitoring and provide seagrass conservation efforts. The study was conducted at the Karang Sewu, Prapat Agung, Labuhan Lalang, and Menjangan areas. The fourth coast had the type of substrate and the different environmental conditions. All the data retrieved using quadrant transect method, and also conducted abiotic data collection such as the type of substrate, temperature, pH, salinity, DO, and light intensity. Based on the survey results known that there are 7 species of seagrass in TNBB of Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata, Halophila ovalis, Halophila minor, Halodule pinifolia and Syringodium isoetifolium. The dominant species are C. rotundata and H. ovalis. The highest relative frequency in Karang Sewu was E. acoroides with a value of 78.13%, while the highest relative frequency in Labuhan Lalang was T. hemprichii with a value of 28.9%. The highest relative frequency in Prapat Agung and Menjangan was C. rotundata with respective value amounted to 48.72% and 48.5%. Labuhan Lalang had the highest species composition with 7 species are E. acoroides, T. hemprichii, C. rotundata, H. ovalis, H. minor, H. pinifolia and S. isoetifolium.
