Join Bay Nature Naturalist, Eric Simons, for a Dock Fouling Excursion at Pillar Point Harbor

Join Bay Nature and writer and naturalist Eric Simons for a dock fouling excursion at Pillar Point Harbor in Half Moon Bay on Friday, June 26th, 2026 from 3:00–5:00pm.

Inspired by Bay Nature’s Fall 2025 story “Finding Bugula,” this event invites participants to explore the strange and surprisingly colorful marine communities living just below the Bay Area’s docks and floating structures.

By carefully peering over the edge of the docks—or even lying flat on your stomach for a closer look—we’ll search for bryozoans, nudibranchs, sponges, tunicates, anemones, and other marine life thriving on pilings, floats, and submerged surfaces. Pillar Point Harbor offers a very different marine environment than the inner Bay, making it an ideal counterpoint to explore. This event is the second in a series of four Friday evening dock fouling outings taking place around the Bay Area this year, each offering a different mix of habitat, marine organisms, and waterfront atmosphere. Following the event, attendees are welcome to continue socializing informally at nearby harbor restaurants and gathering spots.
