Please sign up for this field trip by emailing Susan Schlosser. Susan will send you a link to the waiver.

This easy 2-mile walk will explore a pristine native landscape on the Inverness Fire Road. The route passes through a mixed evergreen forest of bishop pine, madrone and chinquapin with a diverse understory of huckleberry, Labrador tea, ferns and herbaceous perennials. Toward the end of the route, we will admire the low-growing Mt. Vision Ceanothus (Ceanothus gloriosus var. porrectus) and puzzle out the differences between Marin manzanita (Arctostaphylos virgata) and Eastwood manzanita (A. glandulosa).
