Rare and Endangered Plant Species of Puerto Rico and the Virgin Islands: AnAnnotated Checklist

摘要

This paper sought to identify those plant species native to Puerto Rico and theVirgin Islands that best fit the criteria of being at present critically rare and endangered. This effort hopes to encourage the systematic monitoring of individual populations and their status, and stimulate formal studies into the biology of these populations and their status, and stimulate formal studies into the biology of these poorly known species by drawing attention to their status. An effort was made to review the status of those plant species native to the islands whose survival in the wild was threatened, and identify those specific species that (based on their extreme rarity and/or threatened survival) were most critically endangered.
