History and conservation status of the Antillean manatee Trichechus manatus manatus in Hispaniola

Abstract

AbstractTo summarize the state of knowledge of the Endangered Antillean manatee Trichechus manatus manatus in Hispaniola, which comprises the Dominican Republic and Haiti, I reviewed documentary archives from pre-Columbian times to 2013. Manatees were historically abundant in Hispaniola but were hunted for centuries for their meat and other body parts for diverse uses. By the end of the 19th century manatees had become relatively rare around the island. Nevertheless, manatees remain widespread along the coast and occasionally occupy freshwater habitats in the Dominican Republic. In Haiti recent manatee sightings were restricted to two coastal areas. Currently, the manatee population of Hispaniola is perceived to be declining. The most commonly reported threats to the species include hunting, entanglement in fishing gear, boat strikes and disturbance by boat traffic, pollution, and habitat degradation and destruction. In the Dominican Republic longstanding national laws and international agreements protect the species and its habitat, and past conservation actions have raised public awareness about the status of the manatee. In Haiti knowledge of manatees is extremely limited and the species is not legally protected. I propose country-specific and binational recommendations to improve the contemporary conservation of manatees in the Dominican Republic and Haiti.
