Restoration Project

California Department of Fish and Wildlife - Lunada Point

Restoration Objective:

The objective of restoration was to Increasing 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 Apr 1976 – 1st Jan 1977

Action Summary:

At Lunada Point, several thousand adult and juvenile Macrocystis plants were transplanted, mass cultures were dispersed, and gill netting was used to reduce large numbers of herbivorous fishes.

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:

At Lunada Point, kelp was observed in 1976 (0.01ha) where it increased to 0.04ha then decreased in 1977 to 0.02ha.
