Northern California divers 👇⁠
⁠
Join us on Saturday, April 26th, 2025 for our first monthly Sea Urchin Removal Event of the season at Caspar Cove on the beautiful Mendocino Coast!⁠
⁠
Why? Purple sea urchins have overrun the reef, devastating local kelp forests. With your help, we can restore balance and give kelp—and the entire marine ecosystem—a fighting chance.⁠
⁠
Here’s what to expect: ⁠
Date: Saturday, April 26, 2025 ⁠
Time: 8 AM to dusk ⁠
Location: Caspar Cove, Mendocino, CA ⁠
Bring: Dive or snorkel gear + a valid CA fishing license ⁠
Bonus: On-site air compressor available for tanks!⁠
⁠
By volunteering, you’ll help restore kelp forests and connect with a passionate community of scuba divers.⁠
⁠
These events happen every last Saturday of the month through September, so mark your calendars and make an impact!⁠
⁠
More info + gear checklist at our link in bio.⁠

Our latest surveys from Tanker’s Reef in September 2024 reveal that the kelp forest at our restoration site is holding strong — even after coordinated urchin culling efforts ended over a year ago. Here’s what we found:⁠
⁠
📉 Urchin densities remain low: ~3 urchins/m² at the restoration site vs. 5/m² at the control site ⁠
🌱 Giant kelp densities have stayed stable since fall 2023 ⁠
📓 While stipe (stem) densities dropped by 45% in June 2024, they’ve since stabilized ⁠
⁠
This likely points to larger kelp plants being lost over winter, and replaced by new growth in 2024. The kelp forest is showing resilience — a promising sign for long-term recovery.⁠
⁠
Big thanks to @sea.trees for funding these ongoing monitoring efforts. We’ll be back in the field for more surveys in June 2025. ⁠
