Sunday, February 5, 10 a.m. – 2 p.m.
This field trip will follow a moderate 4-mile route from the Rock Spring parking lot to Barth’s Retreat (via the Mickey O’Brien 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. There may be early blooming wild flowers such as milk maids and fetid adders tongue. We plan to repeat this hike each season in 2017.
Meet at the Rock Spring parking lot. Rain Cancels.
