News and Events
from One Tam



Dear Friend,

We hope this monthly newsletter finds you and your family staying healthy and safe.

Last week, we kicked off our popular biannual One Tam Summit with the very apt theme of Climate: Change and Resilience. The Summit brings together One Tam partner staff, scientists, community members, students, and supporters.

We were joined by 188 participants, who gathered to hear presentations about Marin County’s social and ecological health, and the broader context in which we are delivering One Tam community and science programs and projects. Read on to learn how to register for additional sessions this month, held every Thursday from 9am-12pm.

As always, thanks to all of our One Tam members and supporters who invest in our work and the mountain. We are most grateful. Not a member? Join now.

Project Update:
Redwood Creek Trail Realignment Project Begins 

New Redwood Creek Trail Realignment under construction.


We’re excited to announce that construction has begun on the Redwood Creek Trail Realignment Project!

In redesigning this trail segment, One Tam partners are capping off a multi-year collaboration on designing, permitting, and funding for this project. Heavy use and seasonal flooding along a roughly mile-long segment of Redwood Creek trail had led to erosion and sediment run-off into nearby Redwood Creek.

Now, with the new trail realignment, visitors – including hikers and equestrians - will have access to a newly designed trail and bridges that also protect the creek and its inhabitants, including coho salmon and steelhead trout. Additionally, the project allows for future opportunities for restoring floodplain connection.

One Tam partner California State Parks is leading the trail construction effort with support from California Conservation Corps members.

Event: Botanical Illustrations from Mt. Tam — An Upcoming Art Exhibit and Virtual Reception

Do you love nature, art and botanical illustrations? The Northern California Society of Botanical Artists are working on a “floreligium,” or a collection of botanical illustrations, of Mt. Tam that you won’t want to miss.

Join us on Sunday, October 11 at 5pm for a virtual reception to celebrate the opening of the first installment of this floreligium. Following the reception, visit the floreligium exhibit in person at the Marin Art and Garden Center.

iNaturalist Observation of the Month

Thisbe’s tarantula hawk is not a spider or a bird. It’s a large wasp found throughout western North America that mostly feeds on flowers. Females hunt tarantulas engage in parasitoid behavior by laying their eggs in the tarantula to provide nourishment for their young. Unlike Mt. Diablo, Mt. Tamalpais does not have a fall tarantula migration, since true tarantulas are not found in Marin. On Mt. Tamalpais, tarantula hawks have been observed hunting false tarantulas in a dramatic fashion as shown here by iNaturalist user tombrookshire.
