Jaragua-Bahoruco-Enriquillo Biosphere Reserve is a large transboundary biosphere reserve located in the southwest of the Dominican Republic encompassing coastal, lacustrine, karstic and montane environments. It integrates nationally protected areas including Jaragua National Park, Bahía de las Águilas, Sierra de Bahoruco National Park and the Lake Enriquillo basin, and was designated under the UNESCO MAB Programme in 2002. The reserve is notable for high levels of endemism among Hispaniola’s flora and fauna and for its mix of Caribbean dry forest, pine woodland and hypersaline lake ecosystems.
The reserve spans the southwestern peninsula of Hispaniola and includes important features such as Pedernales Province, Independencia Province, Barahona Province, Bahía de las Águilas, Enriquillo Lake, and the Sierra de Neiba foothills. It intersects political and conservation jurisdictions involving the Ministry of Environment and Natural Resources (Dominican Republic), local municipalities like Pedernales, and international partners including UNESCO, IUCN and regional NGOs. The mosaic contains protected areas, buffer zones, multiple community territories, and marine sectors adjacent to the Caribbean Sea and Gulf of Neiba.
Geologically the area rests on the Caribbean Plate near the boundary with the North American Plate and displays limestone karst, alluvial plains and volcanic substrates associated with the island’s orogeny. Prominent landforms include the Sierra de Bahoruco range, the intramontane Enriquillo Valley, and coastal terraces bordering Bahía de las Águilas and Punta Rucia. Lake Enriquillo is a hypersaline terminal lake below sea level, capturing hydrological inputs from the Yaque del Sur River catchment system and influencing local microclimates. Historic tectonic activity linked to the 2010 Haiti earthquake and other Caribbean seismic events shaped drainage patterns and sedimentation within the basin.
The reserve contains Caribbean dry forest, xeric scrub, seasonal broadleaf woodland, pine forest, mangroves, coastal lagoons and hypersaline lacustrine ecosystems. Flora includes endemic taxa found on Hispaniola such as species in genera like Ceratozamia relatives, while fauna comprises endemic reptiles like the Ricord's iguana and island radiations among Anolis lizards. Avifauna includes species associated with Neotropical flyways and endemics recorded in inventories by organizations like BirdLife International; notable birds include species comparable in status to those protected in Los Haitises National Park and Sierra de Bahoruco National Park. Marine and coastal assemblages comprise coral communities similar to those in Reef systems of the Caribbean and provide habitat for green sea turtles, which nest on beaches such as Bahía de las Águilas and are targets of initiatives by groups like Sea Turtle Conservancy and WWF. The hypersaline lake hosts specialist fauna including the endemic Hispaniolan slider relatives and provides important habitat for migratory Phoenicopteridae-like shorebirds.
Management is coordinated among national agencies, municipal governments, international conservation organizations and local communities, with frameworks influenced by UNESCO MAB zoning (core, buffer, transition). Conservation priorities align with action plans endorsed by entities such as the IUCN, Ramsar Convention interests for wetlands, and bilateral projects with institutions similar to USAID and regional universities. Challenges include pressures from agriculture, illegal extraction, invasive species control, and climate-related sea level rise discussed in reports by bodies like the Intergovernmental Panel on Climate Change and regional Caribbean environmental programmes. Adaptive management uses participatory approaches involving community associations, protected area rangers, and technical cooperation with research centers such as Pontificia Universidad Católica Madre y Maestra and Universidad Autónoma de Santo Domingo.
Human communities within and around the reserve include populations of Pedernales, smallholder agriculturalists, artisanal fishers, and tourism operators. Land use mosaics feature shifting cultivation, cattle ranching, charcoal production historically tied to regional trade routes, and coastal fisheries supplying markets in Santo Domingo and cross-border exchange with Haiti. Socioeconomic links involve remittances from diasporas connected to cities like New York City and Miami, and demographic dynamics influenced by migration patterns documented by institutions such as the Economic Commission for Latin America and the Caribbean.
The protected landscape has roots in early Dominican conservation efforts established through national decrees creating Jaragua National Park and Sierra de Bahoruco National Park. International recognition culminated in the 2002 inscription under UNESCO’s Man and the Biosphere Programme, following assessments by experts from IUCN and collaborative proposals supported by municipal authorities and NGOs. Historical episodes relevant to the area include colonial-era land tenure patterns on Hispaniola and 20th-century infrastructure projects that altered hydrology and settlement patterns, resonating with broader Caribbean environmental histories referenced in studies by Smithsonian Tropical Research Institute scholars.
Tourist attractions include ecotourism at Bahía de las Águilas, birdwatching in Sierra de Bahoruco, cultural tourism in towns like Barahona, and paleontological points of interest similar to sites studied by researchers at the American Museum of Natural History. Education and outreach are delivered through visitor centers, community guides trained with support from organizations analogous to Conservation International and environmental education curricula developed with regional universities and NGOs. Sustainable tourism programs aim to link local livelihoods with conservation outcomes while drawing best practices from models implemented in Los Haitises National Park and Caribbean biosphere reserves supported by UNESCO.
