Data associated with the 2014 harvest experiment, where Macrocystis canopies were harvested at 5 sites along the coast of British Columbia. Data shown are metrics of kelp recovery (growth, biomass recovered, surface frond production, and surface frond loss) for kelps at each site. Also shown are the percentage of reproductive sporophylls at each site. Data set also includes predictor variables (wave exposure, average temperature, max temperature, standard deviation of temperature, frond and plant density at the site, and metrics of individual kelp size [surface length before harvest, the number of fronds at the surface before harvest, and the biomass removed).
