Caspar Cove Purple Urchin Culling - Dive Log
California’s north coast has been devastated by declines in bull kelp, resulting in part from increases in native purple sea urchin populations. The purpose of this project is to investigate whether in-water purple urchin culling by volunteer divers can support kelp regrowth at Caspar Cove. Results will help managers determine whether in-water purple urchin culling is a useful kelp restoration tool more broadly.

Divers should only target purple urchins as per temporary regulatory amendment. If you need help distinguishing between purple and red urchins, please see the field guide below.  

Each individual diver should complete one log entry per dive.  

Divers must have a valid recreational fishing license (except on July 4 and Labor Day) 

For up-to-the-minute COVID-19 information, contact the Mendocino County Public Health Department call center: (707) 234-6052.
