“…Threats to manatees world-wide are habitat loss, illegal hunting and boat collisions [2,4]. These pressures endanger the persistence of manatees worldwide and the full effects of these and uncontrolled human population growth on the species are unknown [5–7].…”

Tropical coastal wetlands have a rich biodiversity, a restricted geographic distribution and are a prime habitat for manatees in the regions where they occur in the Neotropics. Human pressures affect the persistence of tropical wetland ecosystems and hence of manatees. In the continental Neotropics, the West Indian manatee (Trichechus manatus) is represented in Mexico by the subspecies T. m. manatus. Lack of information regarding the current distribution of manatees in Mexico hampers conservation approaches of this marine mammal. In this paper we present information on a survey of a population of manatees found in the Catazajá wetlands (ca 60,000ha) in northeast Chiapas, Mexico. We additionally report on manatee conservation efforts spanning seven years aimed at involving the participation of local rural communities. Systematic surveys for the presence of manatees were conducted between Feb-Nov, 2007 by sightings along sampling transects in waterways, recording of manatee presence as evidenced by recently browsed aquatic vegetation, presence of stranded individuals and presence of deceased manatees. Additionally, some records of manatee presence underwater were obtained by using a sidescan sonar system. Lastly, interviews with 120 individuals from 10 local communities also yielded information on manatee presence in the wetland system. A map of the study area divided into a grid of 50 ha cells was used to plot and quantify the records of manatee presence obtained with the above procedures. Results indicated presence of manatees in 11% (ca 4,850 ha) of the 50 ha cells into which the study area was divided. Records indicate presence of manatees throughout the wetland, but with concentration in particular sectors. Involvement of local communities in manatee conservation has resulted in designating the Catazajá wetlands as a natural protected area.Keywords: Trichechus manatus, West Indian manatee, wetlands, Neotropics, manatee conservation, Mexico Los humedales costeros del Neotrópico son ricos en biodiversidad, presentan una distribución geográfica restringida y son los hábitats principales para poblaciones de manatíes en las regiones en donde estos ocurren. Los humedales costeros están bajo riesgo debido a presiones humanas, impactando la persistencia de poblaciones de manatíes. En la región continental del Neotrópico, el manatí esta representado por la especie Trichechus manatus y en México por la subespecie T. m. manatus. La falta de información básica sobre la distribución actual de poblaciones de manatíes en México dificulta acciones de conservación de este mamífero marino. En este trabajo presentamos los resultados de un reconocimiento de la población de manatíes en los humedales de Catazajá (ca 60,000 ha) en la región noreste del estado de Chiapas, cercana al Golfo de México. También reportamos avances en programas de conservación de los manatíes que involucran a las comunidades locales. Entre Febrero y Noviembre del 2007 se efectuaron reconocimientos sobre presencia de manatíes en el humedal a través...

“…During the conquest and colonization of the West Indies the eastern part of Hispaniola was primarily a Spanish colony and the western part a French colony. Manatees were considered an extraordinary and tasty fish, and descriptions of manatees were not uncommon in accounts of European voyagers in the 15–19th centuries (Durand, 1983). Nevertheless, only a limited number of these historical documents were included in regional reviews (Lefebvre et al, 1989, 2001) and management plans for the West Indian manatee (UNEP, 1995, 2010), and pertinent literature about Hispaniola written in Spanish and French was excluded.…”

History and conservation status of the Antillean manateeTrichechus manatus manatusin Hispaniola

To 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.
