Mangrove diversity and sustainability in karangsong village of indramayu regency, west java

Abstract

Mangrove forests in the northern coastal region of Karangsong Village, Indramayu Regency, West Java, form a crucial component of the livelihoods of coastal communities. The objective of this research is to know the diversity of species and mangrove vegetation based on growth level. The research method is explorative survey technique method. The data collection for the research vegetation data from 10 plots divided from observed tracks. This study resulted in the observation 9 species of plants: Avicennia marina, Avicennia alba, Rhizophora mucronata, Rhizophora stylosa, Rhizophora apiculata, Terminalia catappa, Casuarina equisetifolia, Ziziphus mauritiana, and Thespesia populnea. From the analysis, it is known Rhizopora mucronata are the dominant species in the Karangsong Village Mangrove Ecotourism area within three growth phases (seedling, sapling, and mature), which evidenced from the frequency of their presence in 7 (seven) sample plots. Based on the analysis of data obtained, the index of diversity (H’) of vegetation in mangroves and coastal of study area is 1.75, which means that this area has medium vegetation diversity. The calculated Dominancy Index for Karangsong Village Mangrove Ecotourism area is 0.210, which indicates that mangrove species has scattered growth pattern, thus means moderately high in diversity.

Identification of species composing the Bagik Batu mangrove ecosystem, Jerowaru, Indonesia

“…Based on the data above, even though the substrate is sandy and slightly rocky, the Rhizophora type is a type of mangrove that is almost always found in every plant category, both in the Tree, Sapling, and Seedling categories. This is due to the ability of Rhizophora mangroves to live in various substrate conditions [11], unlike other types of mangroves.…”
