Bocas del Toro–San Bastimentos Island–San Blas mangroves

The Bocas del Toro-San Bastimentos Island-San Blas mangroves ecoregion (WWF ID:NT1407) covers the mangrove (brackish and saltwater) habitats along the Caribbean Sea coast of Costa Rica and across the northern coast of Panama. An offshore reef and barrier islands of the region help protect the mangroves from destructive waves. The ecoregion has a high number of endangered and threatened species, including the loggerhead sea turtle, green sea turtle, and hawk's bill sea turtle.

Location and description
The ecoregion has two small sites in Costa Rica, one around the bay north of Limón, and another on the Panamanian border in the Jairo Mora Sandoval Gandoca-Manzanillo Mixed Wildlife Refuge. In Panama, the sites are grouped around the outlet of the Changuinola River, and the coast and islands of Bocas del Toro Province. The archipelago around Bastimentos Island guards the entrance to Chiriquí Lagoon, which is mostly surrounded by mangrove swamps. Farther east there are smaller mangrove sites at Colón, Panama, Isla Grande (Bastimentos, Portobelo), and the western side of the Gulf of Guna Yala.

Immediately inland of the ecoregion mangroves at the forests of the Isthmian-Atlantic moist forests ecoregion.

This climate is characterized by relatively even temperatures throughout the year, and a pronounced dry season. The driest month has less than 60 mm of precipitation, and is drier than the average month. Precipitation averages 2,000 mm/year to 4,000 mm/year. The rainy season is May to December.
