The Dominican Republic occupies the eastern portion of the island of Hispaniola. Although several species are severely threatened, all of the considerable diversity of 30 endemic bird species survive, some in areas that have been designated as National Parks. Almost all can be seen in the National Park of Sierra de Bahoruco in the southwest of the country immediately adjacent to the international border with the Republic of Haiti. Endemic species include the Hispaniolan crossbill and Antillean siskin which live in the pine forests, the Antillean Piculet, La Selle Thrush, several species of tanagers, and two species of todies, a family found only on the Caribbean islands. In November, Black-capped Petrels arrive to undertake their courtship flights. The only other known nesting sites of this elusive species are in adjacent areas of Haiti.

National awareness of these biological treasures, however, and a budget that would provide for protection, are almost non-existent. The biggest recent threat has been the creation of a market and distribution center for potatoes and vegetables from Haiti. Several hundred people have occupied the park, making heavy demands on the forest for fuel.

The contrast between the rich biodiversity of the Park and the clear-cut wasteland of adjacent Haiti is striking. Without adequate policy and financing for long-term protection, however, the future of the Park is uncertain. Below is a letter written by Robert Risebrough, past chairman of LAC, to the President of the Dominican Republic following a visit to the Park by several participants in the Meeting of the Caribbean Ornithology Society held in Santo Domingo in 1999. It points out that only an enlightened form of ecotourism is likely to provide long-term economic viability for the region. The newly-elected President has supported a policy that would protect the National Park system, but that policy is itself in need of support.

The LAC, with the Hispaniolan Ornithological Society and the National Aviary, published in 2008 a laminated guide to the common birds of Sierra Bahoruco National Park titled "Aves del Parque Nacional Sierra de Bahoruco." It was distributed in the National Park area and is used in educational programs.
