“…The assessment of the resilience potential of coral reefs was first developed after the coral bleaching event in the year 1998 and it focused on the physical and ecological characteristics of coral reefs that provide some reefs with greater resistance to and/or recovery from coral bleaching [22,23]. Several resilience indicators have been widely developed and proposed for assessing the ecological resilience of coral reefs [24][25][26][27].…”

Coral reefs in the Gulf of Thailand have experienced severe coral bleaching events and anthropogenic disturbances during the last two decades. This study assessed the resilience potential of coral communities at Ko Losin offshore reef sites and Mu Ko Chumphon nearshore coral reefs, in the south of Thailand, by conducting field surveys on the live coral cover, hard substratum composition and diversity and density of juvenile corals. Most study sites had higher percentages of live coral cover compared to dead coral cover. Some inshore and offshore reef sites showed low resilience to coral bleaching events. The total densities of juvenile corals at the study sites were in the range of 0.89–3.73 colonies/m2. The density of the juvenile corals at most reef sites was not dependent on the live coral cover of adult colonies in a reef, particularly for the Acropora communities. We suggest that Ko Losin should be established as a marine protected area, and Mu Ko Chumphon National Park should implement its management plans properly to enhance coral recovery and promote marine ecotourism. Other measures, such as shading, should be also applied at some coral reefs during bleaching periods.

The coral growth rate is affected by several ecological conditions, which could lead to enhancement or deceleration. Good marine habitat and water conditions would escalate coral fragment growth rate on rehabilitation sites. This study was assessed to determine the coral growth rate transplanted on artificial reef-building for rehabilitation purposes and indicated the main driving factors that enhance coral growth rate at Nyamuk Island, Anambas. Benthic communities, coral length, and coral growth rate compared through the year. Analysis of variances and Principal component analysis (PCA) was conducted to indicated differences between variables and analyse driving factors of coral growth rate. Hard coral and sand coverage increasing during observation. Coral length based indicated constant escalation. However, coral growth yearly showed fluctuation with peak growth from 2014 to 2015. PCA exhibited hard coral, dead coral with algae, sponge, and sand played an important role in supporting coral growth on rehabilitation at Anambas. Available niche for other marine faunas built by artificial reef-building could support to preserve of the coral fragments. Acquisitions of hard coral by coral fragments could be supported by good natural hard coral coverage in the habitat. Herbivorous is one factor that could support recent coral reefs.

“…Several studies suggest that the ability of coral reef ecosystems to deal with disturbances and rebuild coral-dominated systems is the only way to manage coral reefs to deal with disturbances associated with global climate change [6][7][8][9] Lembeh Strait was located in the world's coral triangle with high marine biodiversity. Lembeh Strait has unique environmental conditions that play an essential role in distributing and sustaining marine life [10]. Environmental threats that impact coral reefs in the Lembeh Strait come from human disturbances and natural factors.…”

Resilience is the ability of a system to reach equilibrium after a temporary disturbance. When an ecosystem is disturbed, then the recovery of the system is very dependent on the diversity of species that are still left. The remaining communities determine the direction of new successional communities formed after the disturbance has passed, including coral, fish, and other biota communities. This study aimed to determine the level of resilience of coral reef ecosystems on Lembeh Island. The observation was carried out from January 16-19, 2019, at a 7-meter depth. Determination of the coral reef index will refer to coral reef resilience index table. It is found that the resilience of coral reefs on Lembeh Island currently has a high potential for recovery (resilience) from natural stressors based on the 16 parameters. Seven parameters have very high resilience values: the proportion of bleaching resistant species, community resistance to bleaching, taxonomic diversity, size/age distribution, the abundance of reef fish on live coral, and the abundance of coral benthos on live coral and coral disease levels. Lembeh Island is dominated by hard corals measuring between 5.1 to 25 cm (size M) by ~46%, then sizes more than 25 cm (size L) by ~37% and juvenile size (size S) by 17%. The coral health index on Lembeh Island has the capacity to recover if the condition of coral cover is minimally maintained or improved and lower fleshy seaweed cover by increasing the abundance and biomass of herbivorous fish.
