The primary objectives of this document are to (a) present an overview of the status of scientific knowledge, legislation, and conservation efforts in each country where West Indian manatees are found throughout the Caribbean, and (b) provide short- and long-term recommendations for management and conservation. The document is divided into four major sections: 1. An introduction that includes a review of taxonomy, general biology, and general status of manatees in the region. 2. A review of the status of manatees in each range country (including Puerto Rico) where they are found. Specifically, the review considers (a) manatee distribution and abundance, (b) threats and impediments to conservation, (c) the socioeconomic significance of the species to local communities, and (d) legislation and conservation measures. 3. Suggested short-term and long-term recommendations for research and conservation in the region. 4. Essential conservation and research actions needed in specific countries.
