The program
Catalina’s leeward forests are some of the most-visited kelp dives on Earth, and they take a beating every big winter. The Catalina Canopy program exists to find out whether storm-tolerant seedstock and pre-winter reseeding can keep a canopy standing where lift and swell strip it bare.
Drifter vessels seed in the shoulder season, Holdfast nurseries supply genotypes selected for strong haptera — the gripping fingers of the holdfast — and diver crews from the co-op ground-truth every canopy map.
Milestones

2025
Program moves to monitoring: canopy retention 38% better than unsupplemented sites (illustrative).
Councils, fisheries, dive operators and community groups — every Tidewright program runs on local partnership.
