Rock covered by fucus and barnacles

Mearns Rock 1996

What You See

This year, the boulder looks somewhat like it did in 1990. Young Fucus plants cover much of the boulder, young barnacles appear in the open spaces, and the mussels have disappeared.

What's Happening

A second "wave" of recovery has clearly taken hold.
