<strong>Status</strong> <strong>of</strong> <strong>Coral</strong> <strong>Reefs</strong> in Sou<strong>the</strong>rn Tropical America<br />

waters which are sparsely distributed among 26 discrete areas, but comprise three main<br />

groups: (1) <strong>the</strong> mainland coast with fringing reefs on rocky shores, such as <strong>the</strong> Santa Marta<br />

and Urabá areas; (2) reefs on <strong>the</strong> continental shelf around <strong>of</strong>fshore islands, such as <strong>the</strong><br />

Rosario and San Bernardo archipelagos; and (3) <strong>the</strong> oceanic reef complexes <strong>of</strong> <strong>the</strong> San<br />

Andrés Archipelago in <strong>the</strong> Western Caribbean. The complexes illustrate <strong>the</strong> bestdeveloped<br />

coral formations, including atolls, banks, barrier reefs, fringing reefs and patch<br />

reefs. They collectively comprise more than 75% <strong>of</strong> Colombian coral reefs. <strong>Reefs</strong> on <strong>the</strong><br />

Pacific coast are very poor, with Gorgona Island being <strong>the</strong> only site with large coral<br />

formations. There are a few reef patches in Ensenada de Utría and <strong>the</strong> oceanic Isla de<br />

Malpelo, <strong>the</strong> latter is 350km <strong>of</strong>f <strong>the</strong> coast and has coral growing down to 35m depth.<br />

Costa Rica<br />

There are about 100km 2 <strong>of</strong> coral reefs along <strong>the</strong> Caribbean and Pacific coasts <strong>of</strong> Costa Rica.<br />

The 212km long Caribbean coast consists mainly <strong>of</strong> high energy sandy beaches, with corals<br />

growing only in <strong>the</strong> sou<strong>the</strong>ast where a few poorly developed fringing reefs on fossil<br />

carbonate outcrops in three areas: (1) Moin-Limón, which is adversely affected by a large<br />

port; (2) Cahuita Natural Park, which includes <strong>the</strong> largest and best studied fringing reef on<br />

<strong>the</strong> Caribbean coast; and (3) Puerto Viejo-Punta Mona, which has a few minor coral<br />

formations. In contrast, Pacific reefs are more abundant and distributed along <strong>the</strong> 1160km<br />

coast, although <strong>the</strong>y have low coral diversity and are not well developed. The principal<br />

Pacific reefs are near Santa Elena, Bahía Culebra, Isla del Caño and Golfo Dulce, but also in<br />

<strong>the</strong> oceanic Isla del Coco that is 500km <strong>of</strong>fshore. Around 60 hard coral species are known<br />

from <strong>the</strong> Caribbean, while only 18 are recorded from <strong>the</strong> Pacific side.<br />

Panama<br />

There are 2,490km <strong>of</strong> coastline along both <strong>the</strong> Caribbean and Pacific shores, and includes<br />

approximately 290km 2 <strong>of</strong> reefs. Most reefs (99%) are in <strong>the</strong> Caribbean, where <strong>the</strong>re are more<br />

hard coral species (64 species) than <strong>the</strong> Pacific (23 species). Caribbean coral reefs occur along<br />

most <strong>of</strong> <strong>the</strong> coast, with three major areas: (1) <strong>the</strong> western coast (Bocas del Toro-Rio Chagres)<br />

which has <strong>the</strong> highest coral cover <strong>of</strong> all <strong>the</strong> Caribbean reefs in Panama; (2) <strong>the</strong> central coast<br />

(Colón-Isla Grande) which is near <strong>the</strong> major industrial area and <strong>the</strong> most degraded <strong>of</strong> <strong>the</strong>se<br />

Caribbean reefs (less than 4% coral cover); and (3) <strong>the</strong> eastern coast (San Blas or Kuna-Yala<br />

territory), with <strong>the</strong> most extensive and diverse reefs in Panama. Most <strong>of</strong> Panama’s Pacific reefs<br />

occur on islands near <strong>the</strong> coast, comprising two major reef areas: (1) <strong>the</strong> Gulf <strong>of</strong> Chiriqui, with<br />

<strong>the</strong> best fringing reefs and <strong>the</strong> most representative for <strong>the</strong> eastern Pacific region; and (2) <strong>the</strong><br />

Gulf <strong>of</strong> Panamá, including reefs on Las Perlas archipelago, Taboga and Isla Iguana.<br />

Venezuela<br />

<strong>Reefs</strong> occur mainly in three Caribbean areas out <strong>of</strong> total 2,875km <strong>of</strong> Caribbean and Atlantic<br />

coastline in Venezuela: (1) <strong>the</strong> Morrocoy National Park and adjacent reefs (San Esteban,<br />

Turiamo and Ocumare de la Costa), which have <strong>the</strong> best developed coral formations on<br />

<strong>the</strong> continental coast (more than 30 coral species and reef growth to 20m); (2) <strong>the</strong><br />

Mochima National Park and adjacent reefs (Coche and Cubagua islands), with more than 20<br />

coral species growing down to 14m depth; and (3) <strong>the</strong> oceanic islands found more than<br />

100km <strong>of</strong>fshore, with <strong>the</strong> best reef formations <strong>of</strong> Venezuela occurring at Los Roques<br />

archipelago (e.g. 57 coral species <strong>of</strong> and reef growth to more than 50m depth), as well as<br />

<strong>the</strong> Aves, Orchila and Blanquilla islands.<br />
