From monitoring to reporting

MBC Aquatic Sciences has been conducting studies to monitor the health of giant kelp forests in southern California on behalf of the Region Nine Kelp Survey Consortium (RNKSC) since 1983 and the Central Region Kelp Survey Consortium (CRKSC) since 2003. The RNKSC and CRKSC programs combined include all coastal kelp beds from the Ventura River to the USA/Mexico border, representing approximately 81% of the southern California mainland coast (220 of the 270 miles). Quarterly aerial surveys are conducted to determine the areal extent of the surface canopy of each kelp bed, utilizing a method developed by the late Dr. Wheeler North of the California Institute of Technology in 1967.

BOARD MEMBERS

SOUTHERN CALIFORNIA BIGHT REGIONAL AERIAL KELP SURVEYS

Central Region:

• Total coverage increased from 4.9 to 7.9 km2

• 23 beds increased in size
