	There are very few trees on the island: on the northeast side of the island near the shell middens are two clusters of old California buckeyes ("Aesculus californica"), a single red willow ("Salix laevigata") and some blue elderberry ("Sambucus mexicana"). Around the two ponds in the quarry on the southern shore are several arroyo willows ("Salix lasiolepis"). A few non-native Monterey pine ("Pinus radiata") and Monterey cypress ("Cupressus macrocarpa") have also been planted near the caretaker's residence.
