Monitoring Biodiversity Returns of Kelp Restoration Using Environmental DNA (E-DNA). Report of Phase 1

Kelp restoration is a major pillar of Ocean Wise’s Seaforestation Initiative. Ocean Wise and Canadian Kelp Resources (CKR), and Rendezvous Dive Adventures worked together to establish a kelp restoration demonstration site in Rainy Bay, Barkley Sound. Specifically, CKR produced and out-planted green gravel for three species of kelp in Rainy Bay, during the latter half of 2021. Study species include: giant kelp (Macrocystis pyrifera), bull kelp (Nereocystis luetkeana) and sugar kelp (Saccharina latissima). The success of this experiment will be assessed during 2022 and 2023 with a focus on understand the biodiversity benefits of kelp restoration. We used eDNA in a pilot for this purpose in Barkley Sound, Vancouver Island, Canada. We assess here the effectiveness and efficiency of this method, in comparison with diving transects to identify species composition.

Ocean Wise est basé sur le territoire traditionnel et non cédé des peuples Salish de la côte, y compris les territoires des nations xʷməθkwəy̓əm (Musqueam), Skwxwú7mesh (Squamish) et Səl̓ílwətaʔ/Selilwitulh (Tsleil-Waututh). Nous travaillons à travers l'île de la Tortue et au-delà, soutenant les peuples autochtones dans leur travail essentiel de conservation des océans et de la biodiversité chaque fois que cela est possible ou lorsque nous y sommes invités.
