Abstract
This applied research project serves as the first year of a collaborative project between the Tsleil-Waututh Nation and Kelp Rescue Initiative aimed at tailoring bull kelp (Nereocystis luetkeana) restoration methodologies to Burrard Inlet. This research characterized abiotic and biotic conditions at reference sites, compared these conditions to three identified restoration sites to determine their viability for larger-scale restoration, and trialled the green gravel and kelp-seeded tile restoration methods. This study concluded New Brighton Park has sufficiently large substrate to be a restoration site in future years. Naturally recruited N. luetkeana was found from the low intertidal to a maximum depth of 3 metres below chart datum at an average sporophyte density of ~3 sporophytes per m2 in the late summer. The restoration trials saw limited success past April; however, lessons learned suggest outplanting larger kelp-seeded rocks and attaching kelp-seeded tiles to larger substrate could increase restoration success.
