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 Selection Criteria:
The selected site was used because it had historically supported a highly productive abalone fishery, and had experienced a significant recent incursion of C. rodgersii, resulting in the loss of abalone habitat.
Cause Of Decline:
In high numbers, sea urchins can overgraze seaweed communities. On reefs with high densities of sea urchins, the structure of the algal community is damaged, and the abundance and diversity of invertebrates is reduced.
