Coral reef restoration is becoming increasingly popular for coral reef managers to assist in the rejuvenation of coral reefs on a local-scale, with the primary goals of coral restoration programs being to increase live coral cover on the reef, and improve reef structural complexity and reef functionality (Rinkevich, 1995). There have however been concerns regarding the execution of reef restoration approaches on reefs during an era of climate change, ecosystem phase shifts and ecosystem change on reefs (Bruno et al., 2019, Hein et al., 2019, Boström-Einarsson et al., 2018, Hein et al., 2017). Site selection, restoration method selection (eg, coral gardening, coral farming, sexual and asexual propagation, and juvenile and adult transplant successes)(Figure 2-1), host genotype, and sources of transplanted corals are all important factors in coral restoration success and ensuring the health and survival of out-planted coral (Bayraktarov et al., 2016, Boström-Einarsson et al., 2018, Omori, 2019, Forrester et al., 2019, Temmink, In Press, Ishida‐Castañeda et al., 2020, Hein et al., 2020, Goergen et al., 2018). Coral mortality within restoration is highly variable, with many sites recording high mortality following out-planting and within the first year (Bayraktarov et al., 2016, Suzuki et al., 2018, Ishida‐Castañeda et al., 2020, Hein et al., 2020). Restoration efforts and research studies are still in their infancy, and as such there is still limited information available on long-term (5-10 years) survivorship at coral transplant sites, and restoration sites that have been exposed to further degradation events (Bayraktarov et al., 2016). The underlying causes of mortality and …
