Intertidal rocky shores on the coast.
Ecosystem records
No verified terrestrial ecosystem association assigned.
Marine habitat; outside terrestrial BEC zones. Ecosystem records describe broad associations, not known patches or harvesting permission.
Timing and food-use notes
March, April, May. Weather, elevation and local conditions can change timing.
Verify the exact species, intended part and preparation with a qualified regional identifier. Months describe planning windows only.
Comparisons & Common Confusions
Other green algae can resemble sea lettuce. Keep the group-level name distinct from a confirmed species identification and consult the regional reference before considering food use.
Plan the Outing
Check tide times, weather, shore access and current rules. The coastal map is context rather than a water-quality assessment. Our spring window is a planning cue, not a claim that all Ulva is absent outside spring.
Handling & Kitchen Notes
Choose a verified clean site and a complete seaweed preparation reference. Rinsing does not make polluted material suitable for food. B.C. requires live plants to be cut above the holdfast without harming regrowth; check the current official guidance. Read B.C.’s current aquatic plant harvesting guidance ↗
