Abstract : A qualitative ecological survey of the plant communities of San Nicolas Island, California, was accomplished during three on-site visits. Eleven plant communities are recognized, of which six are grouped together into a formation. The historical evidence for development and change of these communities is also discussed. Collection was made of 239 specimens of 100 species. To this collection was added the recent unreported collections of several botanists and the previously reported collections were reviewed in the herbariums. The resulting annotated list of plants has 147 species and varieties, of which 94 are native; 35 previously reported species were not included in this list pending location of specimens. A summary of the literature on the geology, history, climate, and fauna is also presented. (Author)
