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.

Ring Mountain Geology and Wildflowers
End of Westward dr., Park Entrance, 298 Westward Drive, Corte Madera, CA, USRing Mountain Geology and Wildflowers
Saturday, May 30, 2026, 2:30 to 5 pm
Leaders: Nicole Myers and Kristin Jakob
Please sign up for this field trip on Meetup.Join geologist Nicole Myers and botanist Kristin Jakob for a late afternoon ramble on Ring Mountain in Tiburon. Learn how the amazing and unique geology of this mountain is the basis for its landscape, rocks, and soils. We will see the relationship between these landforms and the plant communities that they support.
Geologic highlights are serpentinite outcrops and metamorphic rocks of basaltic origins in the upper portions and sandstone and shale formations on the lower slopes. The nutrient poor serpentinite supports rare plants like the Tiburon Mariposa lily and Marin dwarf flax. Along our route, we will encounter an array of native plants and flowers depending on weather. Wavy-leaved soap plant blossoms start opening about 4 pm, which will make our descent from the mountain enchanting.Directions:
Meet at the end of Westward Dr. off of Paradise Dr. in Tiburon (near 208 Westward). We will connect with the Phyllis Ellman Trail part way up.Bring: Water, a snack. Dress in layers.
Rain cancels. Check Meetup for notification.If you have not done so already, please sign the CNPS Marin 2026 Waiver

Mt. Burdell Habitat Restoration Work Party!
Mt. Burdell, 488 San Carlos Way, Novato, CA, USMt. Burdell Habitat Restoration Work Party!
Thursday, June 4, 9-11am
Leader: Greg Reza, Marin County Parks and Open Space District Volunteer Program Coordinator
Marin CNPS Coordinators: Stacey Pogorzelski and Caroline Christman
Location: Mt. Burdell Open Space Preserve, NovatoJoin a community of habitat restorers! Marin CNPS is partnering with Marin County Open Space District staff to remove invasive species and improve native habitat at Mt. Burdell. Located at the northern edge of Novato, Mt. Burdell has serpentine grasslands with rare plants, an incredible array of oaks, and seasonal streams that support milkweed- the critical host for Monarch butterflies.
During volunteer workdays we use hand tools to remove invasive plant species that threaten grassland and stream corridor ecosystems, including Bermuda buttercup (Oxalis pes-caprae), Himalayan blackberry (Rubus armeniacus), pennyroyal (Mentha pulegium), and yellow star thistle (Centaurea solstitialis). Invasive species can create dense populations that crowd out native plants, which in turns harms the wildlife that depend on them. Removing invasive plants protects habitat for milkweed and other pollinator plants, diverse wildflowers in the grasslands, and the many birds and insects that rely on native plants.
Marin County staff will provide tools and great snacks. Bring a reusable water bottle, sun and wind protection, long pants, sturdy close-toed shoes, and work/garden gloves (gloves provided if you don’t have them).
Heavy rain cancels, cancellations will be posted on Meetup.
Directions: Meet at the San Carlos Way entrance to Mt. Burdell OSP, north of San Marin Drive. Use 488 San Carlos Way for mapping. The work area is a short walk from the San Carlos trailhead.
