Abbott's Lagoon
Abbotts Lagoon Trailhead, 4101 Pierce Point Rd, Inverness, CA, USAbbott’s Lagoon, Pt. Reyes National Seashore
Wednesday, June 3, 2026, 9:30 am – 2 pm
Leaders: Ann Elliott, Carolyn Longstreth, and Stacey Pogorzelski
The gentle, flat two-mile long trail that leads out to Abbott’s Lagoon is a year-round favorite for plant lovers and bird watchers. It passes through coastal scrub, dotted by two marshes, passes over a stream between the upper and lower lagoon, and ends in the dunes near the beach.
In early June we will see the end of the spring blooms and the beginning of the summer flower display. In the coastal scrub, we are likely to see yellow bush lupine, cobweb thistle coast angelica, seaside daisy, and a profusion of California poppies.
As we walk into the dunes, we’ll look for yellow sand verbena, beach evening-primrose, Chamisso bush lupine, and the rare Tidestrom’s lupine.
This will be a fairly flat out and back walk of 4 or 5 miles. We plan to walk into the dunes, covering some areas of loose sand to reach the beach. Those who are not comfortable walking in the dunes can turn around at the end of the maintained path. Stacey will lead those that need to leave early back to the trailhead.
Plants lists for this area include Calflora’s Abbott’s Lagoon Trail and Dunes and the CNPS Abbott’s Lagoon Public Trail list.
Meet at the Abbotts Lagoon trailhead on Pierce Point Road. Dress in layers, bring lunch, water, and sun protection.

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.
