Project Overview
Kelp forest conservation faces many challenges, including escalating stressors such as climate change and loss of key predators of urchins. When the stressor cannot be removed or when kelp populations need an extra boost after losses, restoration via kelp outplanting is an important tool. Growing kelp for outplanting is a relatively simple procedure, but there's nuance to optimizing for scalability and reliability of the process, which takes many steps that must be adjusted for each new kelp species and for use at large scales. In this process, restoration workers consider questions such as how best to grow kelp in a nursery, deliver it to the seafloor so it will survive, and maximize yield while minimizing cost.

Goals and Objectives
The Kelp Rescue Initiative is conducting experiments with the objective of providing answers to practical methods questions and contributing towards a Roadmap to BC Kelp Forest Recovery. This involves testing several different restoration methods (e.g., green gravel, tile, twine, direct seeding) across different environments (e.g., in terms of temperature or grazing pressure), and with varying levels of biodiversity in order to determine which methods are most effective and scalable for different ecoregions.

Research Methods
To advance these goals, researchers at The Kelp Rescue Initiative conduct experiments in the laboratory and field. We have two kelp nurseries, one at the Bamfield Marine Sciences Centre, and one at the Deep Bay Marine Field Station. Experiments in our nurseries target questions such as optimal growing conditions, substrates, and seeding densities for the two kelp species we work with: giant kelp and bull kelp. Outplanting is a step that often involves moving large quantities of heavy material from the nursery to the field. This must be done carefully so as not to dislodge young kelp. Every year, we refine methods to conduct these processes at ever larger scales, which requires different logistics and equipment than at small experimental scales. Finally, we trial some outplanting techniques that involve divers and others that use boat outplanting without divers.
