Tidewright
Aerial dawn view over a coastal restoration site: a work vessel laying seeded lines beside kelp-fringed rocky headlands

Projects · Global programs

Eight programs, six coastlines, one method.

From Tasmania’s east coast — where Tidewright began — to the Humboldt Current, every program shares the same loop: baseline honestly, seed with local genetics, verify publicly, and let harvest and credits fund the next season.

East Coast Tasmania

Scaling

Lumeriah Coast

Tidewright’s first and largest program: re-seeding the giant kelp forests that once stretched unbroken down Tasmania’s east coast.

940 ha seededof 1,600 ha targetsince 2019

Gulf St Vincent, South Australia

Seeding

Kudjela Sea Country

A ranger-led program on Gulf St Vincent’s golden kelp reefs — co-designed from the first dive, with ranger crews running their own surveys.

130 ha seededof 480 ha targetsince 2024

D’Entrecasteaux Channel, Tasmania

Established

Tinderbox Pilot

The little pilot that proved the method: one suburban bay, one patch of barrens, and a forest that grew back where everyone could see it.

75 ha seededof 75 ha targetsince 2021

Northeast Pacific

2 programs

Mendocino County, California

Established

Mendocino Barren Reversal

Pairing commercial urchin ranching with bull-kelp reseeding to roll back the barrens that swallowed Northern California’s forests.

320 ha seededof 700 ha targetsince 2023

Santa Catalina Island, California

Monitoring

Catalina Canopy

A storm-season stress test: keeping Catalina’s iconic giant kelp canopy — and the dive economy built on it — alive through harder winters.

210 ha seededof 260 ha targetsince 2022

Norwegian Sea

1 program

Lofoten Islands, Nordland

Seeding

Lofoten Sugar Kelp Belt

Northern Europe’s cold-water kelp belt is thinning. Lofoten pairs restoration with a winter-harvest protocol that keeps fishing boats working year-round.

85 ha seededof 300 ha targetsince 2024

Northwest Pacific

1 program

South-east Hokkaido

Established

Hokkaido Kombu Coast

Working with Hokkaido’s kombu growers — custodians of the world’s oldest seaweed-farming culture — to buffer wild kombu forests against warming currents.

160 ha seededof 420 ha targetsince 2024

Southeast Pacific (Humboldt Current)

1 program

Coquimbo Region

Seeding

Humboldt Coast Program

Tidewright’s newest coast: the upwelling-rich, heat-shocked shores of the Humboldt Current, seeded in partnership with artisanal dive fishers.

Your coastline could be next.

Every program above began with one council, fishery or community asking the same question: could this work here?
