Baseline Assessment of Montastraea annularis
from Puertorrican Coral Reefs (1999 -2004)
• Coral reefs zones between 10 – 20 m dominated in terms of % substrate cover and rugosity by M. annularis (complex)
• Most reef sites with very high live coral cover (> 40 %) strongly influenced by large, centenary colonies of M. annularis
• M. annularis most prevalent coral of “pristine” reefs - off the west and southwest coasts, oceanic islands, reefs distant from the coast, up-current from rivers, clear water reefs down to 40 m (130’).
• Gradual loss of live coral tissue by M. annularis measured from coastal reefs during 2001- 2005 monitoring period
• 1989 coral bleaching event could have been first serious setback of M. annularis from Puertorrican reefs

CORAL BLEACHING EVENT 2005-06
An intense, regional coral bleaching event associated with high SST affected reef
systems in PR during August - October 2005 causing drastic shifts in the
community structure
Boulder Star Coral, Montastraea annularis was the most severely affected species,
presenting large scale mortalities throughout PR. Reef systems dominated by M.
annularis suffered significant degradation
