The lowlands are mainly between the major American Cordillera System ranges running down the center of the Central American Isthmus and the Caribbean coasts.
In some areas of Central America, such as northern Honduras and Panama, the Caribbean Lowlands are narrow to non-existent. In other areas, such as Nicaragua and eastern Honduras, the lowlands expand into the plains of the Mosquito Coast. Wide coastal plains are also found further north along the Caribbean in Belize.
The lowlands habitats and plant communities are in Neotropic ecoregions
