Abstract

The research was undertaken on Pererenan beach in the Regency of Badung, Bali Province, between September and December, 2006. The study sites occur close to the downstream of Bausan creek, the location of which were part of ”Subak Kedungu” irrigation system (east of the creek) and ”Subak Munggu Tegal Lantang” irrigation system (west of the creek). Samples were taken on low tides periods of the intertidal zones of the beach. Samples were stratified randomly taken on three kinds of substrates: on sand and coral substrates on the west, sand substrates in the middle and hard sandstone on the east, each of which consist of five quadrates of 40 cm x 40 cm. Results of this research showed that on the site have been successfully identified 17 species of macrozoobenthic fauna. None of them were classified as protected species. The macrozoobenthic fauna on Parerenan beach had a medium level of index of diversity (IK = 2,598). This meant that, the beach ecosystem in Pererenan was in a stable condition with a medium level of diversity. From the benefit and problems related to their occurrence, it can be described that macrozoobenthic organisms on this study sites, some can be consumed. Besides, there were also some species which dangerous to human because they can cause bleeding, or dangerous hurt caused by sharp needles.

This research was undertaken in Nusa Lembongan and Nusa Ceningan, District ofNusa Penida, Klungkung Regency, between 2005-2006. This reserach was aimed to find outthe size of area and the status of mangrove forest, kind of species, as well as problems facedby the forest related to its conservation status. From this research it was revealed that thesize of the area where the mangrove available in Nusa Lembongan was around 212 ha, andthere was also mangrove forest in Nusa Ceningan about 15 ha. There were 13 species offlora available on mangrove ecosystem which were classified as true mangroves, while 9kinds were asociated mangroves. From the field observation it was revealed that there is apossible threat to the mangrove forest if there is no good management strategy. Someactivities which were available on the mangrove forest that were potentially provided impactsto sustainability of the forest, such as the use for anchoring boats and mangrove touractivities.
