Analysis of the Pterocarpus officinalis forests in the Gran Estero (Dominican Republic)

Abstract

This paper deals with the geological, historical, bioclimatic and floristic aspects of the northern sector of the Caribbean-Atlantic Subprovince. By means of phytosociological vegetation samples, we focussed our attention on the edaphohygrophilous Pterocarpus officinalis forests and megaforbic plant communities formed by large helophytes. Our paper presents a new endemic association for Hispaniola, the Roystoneo hispaniolanae-Pterocarpetum officinalis nova.
