Mangrove flora as an ecotourism attraction in the Perancak Mangrove, Jembrana Bali

Abstract

The coastal mangroves of Perancak Jembrana Village cover an area of around 177.09 hectares, some of the area (around 10 ha) has been developed into a tourist attraction. The tourism being developed is ecotourism based on ecology, biodiversity, conservation of natural resources, environmental education and economic empowerment of local communities. The aim of the research is to identify and describe the diversity of mangrove flora. Analysis of mangrove vegetation uses the square method, the parameters determined are the number of individuals of each species, the area of canopy cover for each species and the frequency of presence. Diversity was calculated with the Shanon-Wiener index. The research results showed that in the Perancak ecotourism area, 25 mangrove flora were found, consisting of 16 species of true mangrove flora and nine species of associated mangroves. The species that dominate are Rhizophora mucronata (important value 52.63), Rhizophora apiculata (important value 31.93), Avicennia marina (28.70), Rhizophora stylosa (important value 24.81), Avicennia officinalis (important value 17, 73) and Sonneratia alba (important value 16.39). The diversity index (H) is 2.89 and the species evenness index is 0.90. Species diversity in mengrove vegetation with a diversity index >1 and evenness approaching 1 means that the condition of the Perancak mangrove is in the stable/good category. Interpretation of the diversity of mangrove flora, habitus characteristics, fruit morphology, root types, typical substrate types is an interesting attraction for ecotourism activities.
