Restoration Objective:
1) Protect abalone production from key reef locations. 2) Prevent further loss of abalone habitat at key reef locations. 3) Recover recently formed barrens back to healthy habitat.

Site Observations:
Observation Date
31st Jan 2011 – 1st Nov 2014
Action Summary:
Urchin cull and abalone transplants.
Lessons Learned:
1) No culling to take place during spawning June – September. 2) Select Reef Codes / areas that are the most productive for abalone. 3) Focus culling effort on Healthy / Patch barren areas first before attempting to extend out onto the barrens. 4) Be cautious of culling too far out onto full barrens, because of low return for effort. 5) First priority is stopping the formation of new barrens. Protecting reefs from further loss of healthy habitat. 6) Avoid culling bays & sheltered areas because the wrong type of weed may grow back (turfing algae) and be unsuitable for abalone.
Project Outcomes:
Restored kelp forests and enahnced abalone populations.
Key Reasons For Decline:
Overgrazing
Area of Restoration (Ha)
