Coral transplantation has become a potential tool for the restoration of coral cover in degraded reef habitats. Yet, very few investigations have attempted to determine whether there is an advantage for at least two species to be used together in coral transplantation. It is hypothesized that corals would perform better in terms of survival and growth when transplanted in mixed- than in single-species plots. Single-species plots were compared with combinations of two species at several reef sites, using three separate coral species, namely, Porites cylindrica, Pavona frondifera, and Hydnophora rigida. P. cylindrica performed consistently well in terms of survival whether alone or in the presence of another species. In a stressful environment with strong wave action, P. frondifera performed better when mixed with P. cylindrica than when alone. However, this difference was not evident where wave action was weak. The influence of mixing on the growth rates of H. rigida and P. frondifera transplants could not be examined completely because of high mortality because of predation by the starfish Acanthaster planci and the gastropod Drupella sp. Interestingly, the presence of P. cylindrica appeared to minimize the impact of predation on P. frondifera transplants. The setback caused by predation stresses the importance of other factors that influence the outcome of restoration interventions. Future initiatives should take into consideration management measures when selecting sites in relation to wave action and predators, control predator outbreaks, and use coral species, e.g. P. cylindrica that are less susceptible to predation.
