Recruitment and juvenile survivorship can affect population dynamics and resilience. In this paper we present data on brain coral (genera Diploria and Colpophyllia) recruitment and recruit cohort survivorship obtained at three stations in 2001 at San Andres Island (Colombia) as part of the baseline used to develop a Marine Protected Area (MPA) system. Two stations were on the leeward and one on the windward side of the island. Monthly recruitment and cohort survival were measured on PVC panels deployed monthly. Recruitment was significantly lower (ANOVA) on the upper sides of the panels, and started in June until November and with a peak in June at the deepest (20-25 m) leeward station. Cohort survivorship did not vary between stations but Kaplan-Meier survival curve showed higher initial survival. The brain coral recruitment rates are the highest recorded for the Caribbean. We strongly recommend continuing conservation efforts to assist the persistence of these populations.
