Citizen Science
Tide-pooling or beachcombing near Lahaina, you may spot this vivid green seaweed clinging to rocks — and knowing it's here, thriving, tells coastal restoration researchers whether nearshore water quality is holding up or quietly shifting.
Broadleaf Sea Lettuce is a thin, bright green seaweed that looks a bit like crinkled lettuce leaves and grows on rocks in shallow ocean water. Someone spotted and documented it in Lahaina, Hawaii, and the sighting was confirmed as accurate by the iNaturalist community. These kinds of verified observations help scientists track where species are living and whether their ranges are changing over time.
Key Findings
A research-grade (community-verified) observation of Broadleaf Sea Lettuce was recorded in Lahaina, HI, US
Ulva lactuca was identified in a Hawaiian coastal location, contributing a georeferenced data point to its known Pacific distribution
The observation met iNaturalist's research-grade threshold, meaning at least two-thirds of identifiers agreed on the species identification

Coastal ecology examines the complex interactions between plant communities and their environment at the dynamic interface where terrestrial and marine systems meet. Plants in these zones must contend with extreme conditions including salt stress, tidal fluctuation, and shifting sediments, making
