British Columbia Kelp Seaforestation

Kelp forests are one of the most productive ecosystems on Earth, rivaling tropical rainforests in their ability to support biodiversity and sequester carbon. The British Columbia Kelp Seaforestation project restores these underwater forests along the Sunshine Coast, where warming waters and sea urchin overgrazing have caused significant kelp decline. Kelp forests provide critical habitat for over 800 species, including commercially important fish like lingcod and rockfish, as well as marine mammals like sea otters. They also protect coastlines from wave erosion and support local Indigenous communities who have stewarded these waters for millennia. This project plants a mix of kelp species including Giant Kelp (Macrocystis pyrifera), Bull Kelp (Nereocystis luetkeana), and Sugar Kelp (Saccharina latissima). These species form the foundation of healthy Pacific Northwest kelp ecosystems. Unlike terrestrial trees, kelp carbon sequestration is measured differently - through ocean area restored rather than per-unit carbon capture. While kelp does capture significant carbon, this project focuses primarily on marine habitat restoration, biodiversity support, and coastal protection. Kelp seeding occurs during the optimal window of November through January when water temperatures are cooler and young kelp can establish before the growing season.
