ANALYSIS OF MINIMUM LIVABILITY AND SIMILARITY OF VEGETATION TYPES IN MANGROVE FOREST COMMUNITY BLOCKS WITH DIFFERENT FUNCTIONS IN BURUNG ISLAND NATURAL TOURISM PARK

Abstract

In its management, to prevent conflict of interests between the surrounding community and the government, the Burung Island Nature Tourism Park is divided into 5 blocks, and the object of research is the condition of the mangrove forests in 3 blocks, namely the Protection Block, Rehabilitation Block and Utilization Block. The condition of the forests in the three blocks is studied in this research. The aim of the research is to examine the condition and existence of the types of vegetation that make up the forest in the three blocks from the aspect of the minimum liveability value of each type of vegetation in each block, as well as the level of similarity in composition and structure of vegetation types between blocks. Data was collected using the Vegetation Analysis method using systematic plotted paths carried out by purposive sampling in the three blocks. The path is made with a width of 10 m and a length of 100 m, consisting of 9 paths that cut perpendicular to the coastline towards the mainland, with a distance of 100 m between paths. Nine types of vegetation were found, of which Rhizophora mucronata was the most dominant type in the three blocks at all growth levels. All types of vegetation at all growth levels in the three blocks have viability values above the minimum value, and the highest minimum viability value is Rhizophora mucronata. The composition and structure of the seedling and tree communities in the three blocks tend to be similar, while the sapling communities in the Protection Block and the Rehabilitation Block are not similar, but are similar in the Utilization Block. The seedling and tree communities in the Rehabilitation Block are similar to the Utilization Block, while the sapling communities are not similar.
