Restoration Objective:

The objective of restoration was to increase ecosystem services.

Cause Of Decline:

Macrocystis pyrifera beds along the southern California coast were relatively stable prior to 1940. Declines were first reported in 1945 in areas nearest major sewage outfalls. This deterioration progressively affected beds at increasing distances from the outfalls, leaving small patches. Deterioration of kelp accelerated when an influx of warm oceanic water persisted off California from 1957-1959.

Key Reasons For Decline:

Multiple

Site Observations:

Observation Date

1st Jul 1975 – 1st Jan 1977

Action Summary:

A total of 1,307 plants, representing approximately 3700 kg of biomass, was transplanted into the Pt. Vicente site in 1974 and 1975.

Lessons Learned:

This study transplanted juvenile and adult kelp plants from healthy kelp beds to new areas and focused on sea urchin control to ensure successful transplantation.

Project Outcomes:

A surface canopy, measuring 0.08ha, appeared at this site in July 1975, 10 months after work began. This small canopy grew to 0.86ha by January 1976 and to 2.87ha by January 1977.
