The objective of restoration was to re-establish ecosystem services provided by kelp forests, particularly fisheries production. Currently testing Hand harvest of urchin by commercial divers + kelp enhancement as a kelp forest restoration tool.

Site Selection Criteria:

Sites were selected that had historically hosted kelp populations.

Cause Of Decline:

Overgrazing by sea urchins + MH wave led to the decline of macroalgae populations.

Key Reasons For Decline:

Overgrazing

Climate Change

Heatwave

Imbalance
