Our appreciation goes to The New York Botanical Gardens, the International Institute of Tropical Forestry, the United States Geological Survey, Neil Sealey, Ethan Freid, and the Departamento de Inventario de Recursos Naturales (DIRENA, a government mapping agency in the Dominican Republic) for their help in providing maps. John de Freitas, Director of the Netherlands Antilles Conservation Data Center, supplied important data for the Lesser Antilles, and Dayle Barry and Stevie Henry of the U.S. Virgin Islands Conservation Data Center furnished essential data on the Islands. Members of the International Institute of Tropical Forestry who made the October 1998 workshop a success are: Ariel Lugo, Bill Edwards, Olga Ramos, Carlos Rodriguez, and Janet Rivera. Larry Tieszen, Eric Woods, and Zhiliang Zhu of the EROS Data Center and Gina Green, Carol Mayes, and John Tschirky of the Caribbean Division of The Conservancy have provided significant support throughout the project. Thanks also to Bruce Potter and Jean Pierre Bacle of Island Resources Foundation, who provided support at the project concept phase. Eva Vilarrubi, also from The Conservancy, and Margaret Buck provided assistance in the publication of this document. We would especially like to thank Susan Vidal and Ken Gorton, who were instrumental in the compilation of the island maps. Lastly, we would like to commend the support provided by the Caribbean Vegetation Ecology Working Group, for their help at an October 1998 workshop in refining and correcting our earlier maps, and sending in subsequent corrections from their respective institutions.

Executive Summary Background Stretching almost 6,800 km. and composed of a chain of over 1,000 islands, the West Indies have been and continue today to be a center of evolution and ecological diversity. Their geologic histories are varied: some islands are young and still actively volcanic, others older uplifts of fossilized coral reefs, others are but vestiges of once massive volcanic mountain chains which formed large land masses that have been at varying times interconnected and isolated. This complex history has led to the presence of many unique vegetation types which provide habitat for an astonishing diversity of flora and fauna, some of which is endemic to the region, and an alarming proportion of which is also highly threatened. Ultimately, our ability to protect this vast array of species and communities is dependent at the coarse level on our ability to target and conserve representative examples of these vegetation types. Conserving biological diversity at the level of natural communities is an important complementary approach to single-species conservation efforts because natural communities contain important assemblages of species and the habitats that support these species. Improved conservation of the distinct natural vegetation types that occur on Caribbean islands is greatly facilitated if these vegetation types are accurately understood, described, and mapped in a manner that is accepted and respected by the diversity of countries, cultures, and peoples that make up the Caribbean today. The Caribbean Vegetation Classification and Atlas Project has been a key step towards
