The State of Coral Reef Ecosystems of Puerto Rico

INTRODUCTION AND SETTING The Commonwealth of Puerto Rico is comprised of a number of islands in the northern Caribbean, including the island of Puerto Rico and offshore islands such as Culebra, Vieques, Monito, and Desecheo (Figure 3.1). The following information adds to the comprehensive overview of Puertorrican reefs provided in the previous edition of this report (García-Sais et al., 2005). The coral reef ecosystem in Puerto Rico is a complex mosaic of interrelated habitats, including mangrove forests, seagrass beds and coral reefs, as well as other coral communities. Mangrove forests can be found on coral cays and fringing the shoreline along the coast. In areas along the coast where development is occurring, mangrove forests and other wetlands continue to be impacted by cutting, filling and other disturbances. The desire for water access and increases in boating also impact both mangroves and seagrass beds directly through construction and indirectly through changes in water quality associated with accidental spills of petroleum products, accidental groundings and propeller damage, and increases in marine debris. Impacts to these important habitats also lead to effects in coral reefs due to the loss of juvenile habitat for reef species such as spiny lobster, snappers, and groupers. Frias-Torres (2006) demonstrated that, for mangrove-dependent juveniles of goliath grouper in the Florida Keys, spatially complex fringing red mangrove habitat was essential to the growth of this species and the later presence of adults in coral reefs and colonized hardbottom.
