| Adaptive capacity refers to the ability of mangrove ecosystems to respond and adjust to environmental changes, whether driven by natural processes or anthropogenic influences. Mare Island, one of the small islands within the Tidore Islands City region, has been designated as a marine conservation area. However, to date, no specific research has been conducted to assess the adaptive capacity of coastal ecosystems, particularly mangrove ecosystems, in this area. Therefore, this study is essential for evaluating the adaptive capacity of mangroves as part of a sustainable ecosystem management strategy. The primary objective of this research was to quantify and analyze the adaptive capacity of the mangrove ecosystem on Mare Island, Tidore Islands City. Data collection on mangrove ecosystems was conducted through field surveys using the line transect method combined with quadrat sampling techniques and Geographic Information System (GIS) analysis. The assessment of mangrove adaptive capacity was carried out by measuring key parameters that influence the resilience and sustainability of the ecosystem. These parameters include the Mangrove Dimension Index, Average Mangrove Width, Mangrove Zonation, Tree Density, Number of Genera, Substrate Type, and the Proximity of Mangrove Ecosystems to Human Activities. Based on the assessment of seven key parameters, the overall adaptive capacity of the mangrove ecosystem was recorded at 0.504, classifying it as "Moderate." These findings suggest that the mangrove ecosystem has limited capacity to respond to external pressures, including anthropogenic activities and environmental changes. Additionally, the relatively low adaptive capacity highlights the vulnerability of mangrove ecosystems in coastal areas, particularly on small islands, emphasizing their critical condition and the urgent need for conservation efforts. | ||||
