Site Observations:

Observation Date

26th May 1962 – 2nd Nov 1962

Action Summary:

700 pounds of quicklime was distributed from the stern of a towed skiff, killing 90-95% of urchins. Urchins were removed every 2-3 weeks.

Lessons Learned:

The Palos Verdes site had most successful regeneration due to its proximity to a healthy Macrocystis bed.

Project Outcomes:

Ectocarpus regenerated in April. In May, many Macrocystis juveniles were observed. During June, more Macrocystis individuals appeared. By the first week of July, Macrocystis growth was 10-15 feet high. On August 19th and 22nd, sporophytes were counted in quadrats 1 and 2, and most were identified as Macrocystis.
