Seaweed Field Excursion

Join us for an engaging, hands-on exploration of the remarkable world of marine macroalgae. This field-based class invites you into the intertidal zone to discover the ecology, seasonal rhythms, and practical uses of our local seaweeds.

Together, we’ll explore how seaweeds thrive in one of the most dynamic environments on Earth — adapting to tides, weather, and shifting shoreline conditions. You’ll learn to recognize commonly occurring edible species in our region, understand seasonal timing and site considerations for safe harvest, and develop greater confidence navigating intertidal ecosystems.

Harvesting practices will be demonstrated and discussed, though participants will not be harvesting seaweeds for personal use during this program.

Throughout our time together, we will explore:

• Reading the shoreline: tides, substrate, and ecological patterns

• Identification of locally occurring edible seaweeds

• Seasonal growth cycles and harvest windows

• Choosing appropriate harvest locations

• Sustainable harvesting techniques (demonstration)

• Nutritional and wellness applications of seaweeds

We will explore topical, culinary, and creative applications of seaweeds, preparing a seaweed treat together for participants to enjoy and take home — carrying our shoreline learning into practical home uses.

Whether you are curious about edible seaweeds, interested in marine ecology, or simply eager to spend meaningful time in the intertidal, this class offers a rich introduction to working with seaweeds thoughtfully and responsibly.

By the end of the Excursion, you’ll leave with:

• Greater confidence identifying common seaweeds

• Foundational tools for beginning your own responsible harvesting practice

• A basic understanding of seaweeds as food and wellness allies

• A deeper appreciation for our local marine ecosystems
