Intertidal Monitoring

With the ebb and flow of the tides, as well as human-induced events, the Island County beaches are continuously changing. Intertidal monitoring has been developed to assist in determining these changes. Using this field-tested monitoring protocol, trained volunteers collect baseline data over time at specific monitoring sites. The data collected (since 1995) includes beach slope, substrate, and biodiversity.

Each spring and summer we do bio-assessments on over 30 beaches, and the data collected is put into a database for use by us and other scientists. In addition, reports are written, sometimes for the year as a whole, and in some years on a per-beach basis,

Monitoring started in April and will continue through summer, during extreme low tide days.
