Mangrove Degradation, Vegetation Structure, Coastal Ecosystem, Ecological Restoration, Environmental ParametersAbstract
Mangrove ecosystems play a crucial role in maintaining coastal stability and supporting local livelihoods. However, increasing anthropogenic pressures have led to significant degradation in many coastal areas. Previous studies have predominantly focused on large-scale mapping and land cover changes, while local-scale ecological assessments integrating vegetation structure and environmental parameters remain limited. This study aims to analyze mangrove degradation by combining vegetation structure analysis and environmental measurements at a local scale. Field data were collected in October 2023 using a line transect–quadrat method (10 m × 10 m plots). Vegetation parameters included species composition, density, frequency, dominance, and Importance Value Index (IVI), while environmental variables included salinity, temperature, pH, and substrate moisture. Statistical analyses (independent t-test and Pearson correlation) were applied to examine differences and relationships among variables. The results show a low survival rate of 33.20%, significantly below the optimal rehabilitation threshold (60–80%). Environmental factors, particularly salinity and substrate conditions, showed significant correlations with survival and growth parameters (p < 0.05). IVI analysis indicates dominance of specific species with limited regeneration capacity. These findings suggest that mangrove degradation in the study area is driven by both ecological constraints and inappropriate rehabilitation practices. This study contributes to the development of an ecologically based restoration approach by integrating vegetation and environmental indicators at the local scale.
