The potential relative resilience of coral reefs in Wakatobi as a sustainable management foundation
The main objectives of this study are to determine the potential for relative resilience, identify the drivers of potential resilience and priority locations for resilience-based coral reef management in Wakatobi. Data collection locations are spread across four major Wakatobi islands: Wangi Wangi, Kaledupa, Tomia, and Binongko at 5 m depth respectively. Coral reefs resilience assessment in Wakatobi consists of several stages: selecting indicators, collecting and compiling data, analyzing data, and identifying management targets. The highest potential for relative resilience in Wakatobi are station 15 with a value of 1.00 and the lowest is station 8 with a value of 0.69. Relative resilience in high category is 2 stations, med-high 7 stations, med-low 2 stations, and low 4 stations. Relative resilience in high category is able to be distinguished by the high values of bleaching resistant, herbivore biomass, coral cover, and supported by a high diversity of coral. The mid-high category is grouped by the contribution of indicator values coming from coral recruitment and coral diversity, as well as followed by two other indicators such as coral cover and alga cover. Last, the mid-low category and low category tend to be pushed by the low values of coral disease and followed by some other indicators like algae cover. Resilience approach to identify prioritizing stations for management actions is conservation (2 station), fishery management and enforcement (5 station), bleaching monitoring and supporting recovery (3 station), coral reef restoration (2 tation), tourism structuring (10 station), and Land-based sources of pollution reduction (5 station).
