Crowds Depleting Tidepools

Fitzgerald reserve a bit too popular

Maria Alicia Gaura, Chronicle Staff Writer

Friday, February 16, 1996

The tidepool creatures at the Fitzgerald Marine Reserve at Moss Beach are

pretty tough -- they tolerate crashing waves and grinding sand, alternately

submerged in saltwater and exposed to the wind.

But the denizens of this shallow reef are succumbing to a new menace -- the

curiosity of schoolchildren and the trampling of thousands of little feet.

UCSD Biologists' Study Links Human Impacts Along The

Coast To Size Declines Of Marine Snails

February 28, 2003

The average size of limpets along the Southern California coast has

declined significantly over the past century and collection by humans

appears to be the culprit, according to a study led by biologists at the

University of California, San Diego.
