MANGROVE VEGETATION MANAGEMENT IN MERTASARI-SANUR BEACH AREA

Mertasari Beach is one of the beautiful beach series located in Sanur Village which is now developed as an attractive tourist attraction. One of the important backgrounds that support the beauty of this beach is the development of mangrove ecosystems with thick muddy substrates along the river paths so that it is suitable to grow both true mangrove and associated mangrove vegetation. Ecologically the existence of mangroves can function to withstand abrasion and intrusion of sea water entering the land.

This research aims to manage mangrove vegetation in the Mersasri Beach area of ​​Sanur, as an effort to sustainably preserve the beach. All types of mangroves can function physically and ecologically to coastal areas so that their ecosystem needs to be maintained in a sustainable manner

This research was conducted on pure stands of mangrove forests in Sanur's Mertasari Coast Area with an area of ​​10 hectares, conducted for 3 months starting in May-July 2020. The sampling method was carried out using the Plotless Methods. Primary data both vegetation data and environmental data (soil data) were taken at the observation location, while secondary data (climate data) were taken from the BMKG City Coordinator in Denpasar. While the data analysis is done by analyzing vegetation by calculating the parameters of vegetation including: relative density, relative frequency, relative dominance, Important Value Index, Diversity Index, Distribution pattern of species, and status of vegetation types found whether classified as rare or not determined based on government regulations Republic of Indonesia No. 7 of 1999. While soil data (Texture, structure, N, P K) were analyzed in the soil science laboratory of the Faculty of Agriculture Udayana University.

To maintain the balance of the mangrove ecosystem and the development of tourism in the Mertasari Coast of Sanur, it is necessary to have an integrated mangrove management effort between the government and the community
