Carson Ridge Serpentine Flora

June 21 @ 9:00 am - 1:00 pm

Join us for a walk on Carson Ridge through serpentine chaparral. We can either complete a loop hike of 3.5 miles: out Pine Mountain Fire Road, Oat Hill Fire Road, Old Sled Trail and then back to the parking area. However, if we are enjoying a slower pace we can make it a shorter out and back hike. There is some up and down on the whole loop, but the first half mile is fairly flat for those who want to just join us for the first bit and skip the climbing. This is a great place to learn serpentine-specialist shrubs – leather oak (Quercus durata), Jepson’s ceanothus (Ceanothus jepsonii), and Tamalpais manzanita (Arctostaphylos montana ssp. montana), which are distinctive year-round. Our timing is good for the late season serpentine herbs such as rosin weed (Calycadenia multiglandulosa) and the rare Tamalpais lessingia (Lessingia micradenia ssp. micradenia) . We’ll also have a chance to take our lunch break in the shade of one of the few serpentine-specialist trees, Sargent cypress (Hesperocyparis sargentii).
