Animals and Plants

Land mammals on the islands are few and unique. The only native land mammals are the island fox, the island deer mouse, the harvest mouse and the spotted skunk. The island foxes and mice have further evolved independently on each island within the park. Bats are found here as well. Sea mammals include many species of pinnipeds (seals and sea lions), whales and dolphins.

Reptiles and amphibians are few, and include four lizards, one salamander, one frog, and two non-venomous snakes.

The isolation of the islands from the mainland is no barrier to birds, and there have been 384 species recorded on or near the islands to date. The NPS has prepared a
checklist of park birds.

About 790 plant varieties have been identified in the park, over 200 of which are non-native, invasive species. The major plant systems on the islands include coastal dune, coastal bluff, coastal sage scrub, grasslands, chaparral, island oak woodlands, mixed hardwood woodlands, pine stands, and riparian areas.
