This work addressed the following questions: 1a) Can commercial divers be coordinated to reduce urchins to target densities (< 2 urchins/m2) and maintain this urchin density at sites along the North coast? 1b) What is the cost and effort (logistics and time investment) required to achieve and maintain this target urchin density? 2) How does kelp density change following urchin removals, compared to un-restored control sites?
