Ring Mountain Habitat Restoration Work Days

Ring Mountain Habitat Restoration Work Days
Fridays, April 10 and May 8, 2026, 9:30am-12pm
Leader: Amanda Magallanes, Ring Mountain Stewardship Coordinator
Marin CNPS Coordinator: Caroline Christman
Location: Ring Mountain Preserve, Tiburon

Ring Mountain is well-known for beautiful views and stunning wildflower displays. Its serpentine grasslands are home to several rare plants including the Oakland star tulip ( Calochortus umbellatus ) and the Tiburon mariposa lily ( Calochortus tiburonensis ), which is found nowhere else. CNPS has a long history of supporting Ring Mountain and is continuing that work with a stewardship focus. Join us for 2nd Friday work days for a morning of hands-on work to protect
native habitat. We will focus on removing non-native invasive plants, such as tocalote (Centaurea melitensis), false brome ( Brachypodium distachyon ), and Italian thistle (Carduus pycnocephalus). Removing invasive plants frees space and resources for native grasses and wildflowers to thrive. After a morning of rewarding work, Amanda will lead a short plant walk to enjoy the abundant wildflowers including tidy tips, goldfields, and owl’s clover, and to see if the Tiburon mariposa lily is blooming.

During the work day we will be using hand tools to remove invasive plants and will be kneeling and working in tall grass. This location is exposed and can be windy. Marin County staff will provide tools and gloves. Bring a reusable water bottle and a snack, sun and wind protection, long pants, and sturdy close-toed shoes.

Limit: 15 attendees

Heavy rain cancels; cancellations will be posted on Meetup.

Directions: Meet at the gate at the end of Taylor Rd. in Tiburon (dead-end street). From there we will walk together to our weeding site, which is approximately 0.3 miles with 100 ft of elevation gain (about a 10-minute walk).
