Mangrove Vegetation Condition Based on Mangrove Canopy Cover Distribution in, Rembang Regency, Central Java, Indonesia

Mangrove vegetation plays an important role in maintaining the balance of coastal ecosystems, yet its existence is increasingly threatened by human activities. Rembang Subdistrict is one of the areas affected by these threats. This study aims to analyse the condition of mangrove vegetation based on canopy cover using the NDVI (Normalized Difference Vegetation Index) in three coastal villages of Rembang Subdistrict: Pasar Banggi, Tireman, and Kabongan Lor. NDVI is suitable for mangrove analysis because it sensitively reflects vegetation density and health, allowing accurate detecteion of mangrove conditions. Canopy cover distribution was obtained from the processing of Sentinel-2A satellite imagery acquired in September 2024 with standard corrections. The mangrove vegetation condition was determined based on the guidelines for inventory and identification of critical land by the Ministry of Forestry (2005). The results show that NDVI values ranged from 0.2 to 0.6, indicating variations from sparse to dense mangrove cover. Such variation suggests localized degradation patterns within the mangrove ecosystem. Further research is needed to enrich the data and serve as a guide for mangrove area development in Rembang Subdistrict.
