Mangrove ecosystems play a vital role in providing coastal protection, carbon sequestration, and ecological resilience. However, increasing degradation due to anthropogenic pressures threatens their sustainability. This study examines the variation in mangrove vegetation structure in Pasar Rawa Village, North Sumatra, by evaluating ecological conditions across three transects with varying levels of degradation. Using the nested sampling method, data were collected on species composition, density, and regeneration across seedling, sapling, and tree strata. Results show a clear degradation gradient: Transect 1 (light damage) is dominated by Rhizophora sp. with a stable community; Transect 2 (moderate damage) shows greater species diversity and transitional succession; Transect 3 (severe damage) has low density and species dominance. While natural regeneration is still present in all transects, its success depends on controlling anthropogenic activities and supporting ecological recovery. Therefore, adaptive conservation strategies that include community participation, regulation enforcement, and species-specific replanting are crucial. These findings offer a spatially explicit model for mangrove rehabilitation based on degradation levels, contributing to both scientific knowledge and local policy development.
