Tidal Marsh Appreciation

Tidal salt marshes flood twice each day. They provide critical habitat for marine invertebrates such as oysters, mussels, and clams, shorebirds, and specialized native plants like pickleweed. Additionally, the baylands are on the Pacific Flyway, the great bird migration route between Alaska and South America. But wetlands are easy to overlook, often underappreciated, and threatened by climate change. Join Docent Naturalists Susan Bernhard, Ann Reisenauer, and Alison Hurst to explore the flora, fauna, and environmental issues of the salt marshes on this leisurely-paced, family-friendly walk along the Bay Trail.

Where to Meet

Meet at the Ravenswood Parking Area. From Highway 101, exit on University Avenue. Follow University Ave. north (about four long blocks) to Bay Road.  Turn right on Bay Rd. and follow it to the very end (about 1.2 miles).  The preserve entrance and parking lot are marked with large signs.
