Three radically different national parks within the Dominican Republic make up a UNESCO “Biosphere Reserve,” a cornucopia of biodiversity where countless endemic species inhabit a wide variety of ecosystems. The Reserva de la Biosfera series spotlights each of these parks in individual 15-minute episodes: Jaragua, one of the Carribean’s largest coastal protected areas, the iconic mountain landscape of the Sierra de Bahuroco, and the pristine salt lake of Enriquillo.
