Offshore rocks provide nesting and roosting habitat for birds. Broad rocky inter tidal zones and offshore islands create complex wildlife habitat-rich feeding zones for fish, and invertebrates as well as nest and perch habitats for watchful bald eagles and peregrine falcons. The Olympic Coast's remoteness assures that inter tidal communities are spared the pressure of sheer numbers of people. In this wild environment, habitats remain intact and organisms interact through natural processes, including competition for space and predation. Eroded headlands like Point of Arches attest to forces of the sea as it constantly assaults the shore.
Sand beaches are home to many types of burrowing organisms.
At high tide many emerge to feed in the surging water. The combination of wild forest and wild ocean marks the boundaries of two ecological systems. Every surface in the rocky inter tidal zone is used by something. Predatory ochre sea stars roam among communities of green sea anemones and rockweed searching for mussels. Listed as threatened under the Endangered Species Act, Stellar Sea Lions bask on offshore haulouts in Olympic Coast.
