Monarch Citizen Science

monarch monitoring

The Monarch Citizen Science program conducts weekly monarch counts at the Pacific Grove Monarch Sanctuary from November to February. Data collection includes estimating number of monarchs present, collecting weather data, and entering this information into a database for scientific analysis. During a three-week period around Thanksgiving, observers participate in a statewide Western Monarch Thanksgiving Count coordinated by the Xerces Society. The Museum's participation entails counting at nine other sites in Monterey County besides the Pacific Grove Sanctuary.
