Restoration Project

University of California Institute of Marine Science - Cameo Shores

Restoration Objective:

The objective of restoration efforts was to restore lost Macrocystis forests and their associated biological and economic value.

Site Selection Criteria:

A site was selected with historical Macrocystis beds.

Cause Of Decline:

Two years of abnormally high sea surface temperatures from 1957 - 1959 caused the complete loss of the last remaining Macrocystis stands along Paolo Verde.

Key Reasons For Decline:

Ocean warming

Lessons Learned:

None reported

Project Outcomes:

Macrocystis failed to re-establish in the region from Pelican Point to Newport Bay for a period of 12 to 14 years.

Nature of Disturbance:

Sedimentation and warm water caused loss of transplants.

Key Reasons For Decline:

Ocean warming
