Thursday, July 16, 2026 10 am to 2 pm
Leaders: Anna Gil and Kurt Rademacher
Please sign up for this field trip on Meetup.
In our summer, it’s spring in the Sierra. If you can’t get to the mountains, don’t worry, the mountains will come to you. More specifically, to the Siskiyous and Sierra sections of the beautiful Tilden Botanic Garden in Berkeley (just an hour away). To word that another way, when the heat of summer has baked the Bay Area hills, it’s still green and gorgeous at the Tilden Botanic Garden.
The Regional Parks Botanic Garden is a “living museum” of California’s varied plant communities, from deserts and alpine meadows to chaparral and coastal rainforests. We will explore the seasonal highlights of the garden with Botanic Garden Docent Anna Gil (also an active Marin Chapter member).
Directions: East Bay Regional Parks Botanic Garden, Tilden Park, via Shasta Road approach, Berkeley. Intersection of Wildcat Canyon Road and South Park Road.

Habitat Restoration at Alder Creek Preserve, Inverness
Alder Creek Preserve, Inverness, CA, 105 Vision Rd #101, Inverness, CA, USJoin CNPS and Friends to weed the Alder Creek Preserve restoration site in Inverness.
In 2023, the Inverness Association (IA), cleared the site of a large acacia forest. Since then, an enthusiastic group of IA members, neighbors, and SPAWN volunteers have planted a mix of native trees and shrubs and watered them throughout the summer.
Now the focus turns to tackling the weeds: acacia seedlings, poison hemlock, vinca, African veldt grass, and others. We'd love to have your help!
Location: The site is located about a 1/2 mile north of Inverness village, at the corner of Sir Francis Drake Blvd and Vision Rd. For more information, contact Carolyn Longstreth at cklongstreth@gmail.com.
