The Western Monarch Thanksgiving Count
The Western Monarch Thanksgiving Count is a yearly effort of volunteer citizen monitors to collect data on the status of monarch populations overwintering along the California coast. Thanks to the extraordinary efforts of a cadre of volunteers, we have over a decade of data demonstrating that monarchs have undergone a dramatic decline in the western U.S. This effort is coordinated by Dennis Frey, Shawna Stevens and Mia Monroe, in collaboration with the Xerces Society.
Southwest Monarch Study
The Southwest Monarch Study studies the migration patterns of monarch butterflies in Arizona. Their activities include tagging monarchs, monitoring milkweed populations, and searching for habitats that attract and support monarchs. People of all ages are welcome to participate. Southwest Monarch Study also provides educational programs to raise monarch awareness.
