Learn about Mount Umunhum’s natural and cultural history, unique flora and fauna, the Mount Umunhum Summit Restoration Project planning and implementation, and the ongoing vegetation restoration work occurring at the summit. The Mount Umunhum summit has a variety of vistas, ADA accessible pathways, interpretive displays and two weather shelters. 


Coyote Ceanothus (Ceanothus ferrisiae) Population Creation Site on Coyote Ridge: Assisted Colonization of an Endangered Chaparral Shrub

Wednesday, October 19, 9:00 AM – 2:00 PM

Field Trip Location: Coyote Ridge, Morgan Hill, southern Santa Clara County

Instructor: Janell Hillman (Santa Clara Valley Water District), Diana Benner (The Watershed Nursery), and Ted Swiecki (Phytosphere Research)

Registration Fees: $45 early registration/$55 regular registration

The Coyote Ceanothus mitigation project was initiated in 2011 to compensate for impacts from the planned Anderson Dam Seismic Retrofit Project. The population creation site located on Coyote Ridge was first planted in 2014 with annual planting since then. We will tour the mitigation site, see planting areas in gray pine woodland, serpentine chaparral, serpentine grassland and Ca sagebrush scrub, and discuss successes and challenges associated with managed relocation of a federally endangered chaparral shrub restricted to serpentine soil. Topics include selection of a suitable introduction site to create a functional plant community, ecological considerations, regulatory requirements, planting methods, site maintenance, and sanitation practices to prevent plant pathogen introduction. We will also see several other endangered plant species and natural communities, and if we’re lucky, the tarantulas will be out! A beautiful view of the Diablo Range foothills, Mt. Hamilton, and Lick Observatory is pretty much guaranteed.


Regional Parks Botanic Garden at Tilden

Wednesday, October 19, 9:00 AM – 3:00 PM

Field Trip Location: Berkeley, CA

Instructor: Bart O’Brien (Regional Parks Botanic Garden)

Registration Fees: $45 early registration/$55 regular registration

Join East Bay Regional Parks Botanic Garden director Bart O’Brien for a botanical tour through the state of California within the garden’s 10 acres at Tilden Regional Park in the Berkeley Hills. This fall walk will highlight some of the fall colors, fruits and berries that native flora provide for the local fauna. We will also see newly added areas at the botanic garden. If you haven’t visited lately, the new crevice garden (featuring exciting alpine plants of the high Sierra in 116.25 tons of schist and slate) is a must see. 

At the Regional Parks Botanic Garden, mid-October is often a good time for fall color on Acer circinatum, Acer macrophyllum, Vitis ‘Roger’s Red’, Cornus (nuttallii, glabrata, sericea, sessilis), Fraxinus velutina, and many species of Salix. Showy fall fruits can normally be found on snowberries, madrones, and toyons. Depending on the year, the very first flowering manzanitas (refugioensis) and currants (Ribes malvaceum) often start in October. Late summer bloomers, particularly some of the wild buckwheats (Eriogonum cinereum and others), and some members of the Asteraceae are at their best – unless there are significant early rains (which doesn’t seem likely).
