Identifikasi Jenis-Jenis Mangrove Dan Pemanfaatan Di Kampung Sorendiweri Distrik Supiori Timur Kabupaten Supiori Provinsi Papua

Abstract

This study aims to identify mangrove species, analyze vegetation structure, and examine community utilization patterns in Sorendiweri Village, East Supiori District, Supiori Regency. Field observations were conducted from July to August 2017 using transect and plot methods following Bengen (2001). A total of 21–22 mangrove species from 8–9 families were recorded, with Rhizophoraceae identified as the most dominant group. Species distribution was influenced by substrate conditions, primarily fine mud, sandy mud, and muddy sand, which support mangrove growth in the frontal coastal zone. Vegetation structure analysis revealed that Rhizophora apiculata had the highest absolute density among tree categories (5.1 individuals/m²), while Bruguiera gymnorhiza dominated the sapling category (0.135 individuals/m²). In the seedling category, Rhizophora mucronata showed the highest density (4.2 individuals/m²), whereas several species such as Avicennia alba and Sonneratia ovata exhibited the lowest densities. Overall, the mangrove ecosystem in Sorendiweri demonstrates good species diversity and vegetation density, although it faces threats from logging associated with development activities. The findings provide essential information for regional development planning, environmental management, and the promotion of mangrove-based ecotourism in Supiori.
