Abstract

Coastal watersheds strongly impact the near-shore marine environ- ment with freshwater inundation and runoff from the land. At Leo Carillo State Beach in Malibu, California, we have noticed marked effects of stormwater runoff on the local marine fauna. The aggregating sea anemone expels symbiotic algae under the influence of hyposaline stress, causing bleaching. The number and distribution of bleached sea anemones have increased dramatically from 1992 to 1995 at Leo Carillo State Beach under the influence of increased rainfall and the artificial broadening of the arroyo channel at its mouth.
