Description: Many exotic tree species have been imported into Puerto Rico for their wood, fruit, and use as coffee shade and ornamentals. Some of these trees have naturalized (reproduced without human intervention) and some have escaped into natural forests. At least 118 exotic species are reproducing in Puerto Rico. Estimates are given for the general rate of spread and future abundance of each species as well as the environmental requirements. Species that are abundant, widespread, and competing in natural stands, as well as those likely to do so in the future, are identified.
Keywords: escaped species, introduced species, reproduction, tree flora
