Mitigating the effects of climate change on habitat-forming seaweeds in the Salish Sea

Kelps are large brown algae that can form complex marine “forests”. Many marine species, including salmon, use these kelp forests as habitat. However, kelps in the Salish Sea have been declining in recent years. This has likely been driven, at least in part, by ocean warming. If we are to predict how kelp losses might progress in the future, we need to know more about the thermal limits of different kelp species. We also must take action to safeguard these important organisms. For this project, the thermal limits of multiple populations of bull kelp (Nereocystis luetkeana), the principal canopy-forming kelp in the Salish Sea, will be characterized experimentally. Methods will also be established for storing bull kelp propagules in a “seed bank” that can be used to protect and restore kelp populations. This work will directly benefit the salmon that rely on the Salish Sea’s kelp forests, which will contribute to the Pacific Salmon Foundation’s mission to conserve salmon populations in Pacific Canada.
