| Abstract | ||
| Mangrove ecosystems play a critical role in maintaining coastal resilience, supporting biodiversity, and mitigating the impacts of climate change. This study investigated the health and resilience of mangrove forests in Desa Sarang Burung, West Kalimantan, using two key ecological indicators: mangrove density and the important value index (IVI). Field observations and data analysis reveal that areas with higher mangrove density and strong IVI scores exhibit greater ecosystem stability and biodiversity richness. Four mangrove species were identified: A. marina, A. lanata, B. cylindrica, and R. apiculata. A. marina had the highest IVI across all sampling stations (150.62–263.55%), followed by B. cylindrica (36.45–108.39%), R. apiculata (26%), and A. lanata (14.96%). This dominance hierarchy was consistent across all growth stages, including saplings and seedlings. These indicators effectively reflect the condition of mangrove ecosystems and provide a practical basis for assessing their ecological integrity. The findings highlight the importance of integrating scientific monitoring with community-based conservation efforts to ensure long-term ecosystem health. This research offers valuable insights for informing sustainable coastal development strategies and enhancing local environmental management practices in vulnerable coastal regions. | ||
