Ecological Manipulation

Trials were run in the Mercury Passage to understand impediments to Macrocystis re-establishment. This included four treatments:

  1. Transplanting Macrocystisdirectly on to a site
  2. Clearing urchins and then transplanting
  3. Clearing Undaria (an invasive seaweed) and then transplanting
  4. Clearing both urchins and Undariaand then transplanting.
