10 a.m. to 2 p.m.
This field trip will follow a moderate 4-mile route from the Rock Springs parking lot to Barth’s Retreat (via the Mickey O’Brian Trail) and Potrero Meadows. We’ll observe the diverse ecology of Mt. Tamalpais , including meadows, mixed evergreen forest, serpentine outcrops, and chaparral. We’ll look at the big picture of ecologically diverse plant communities and changes observed over the past decades. Plants we expect to see on the narrow foot trail include huckleberry, California bay, Douglas fir, madrone, live oaks, sword and giant chain ferns, moss-covered rocks, buckthorn, manzanita , and Sargent Cypress.
