Last winter, volunteers from across the Southeast and Gulf states provided more than 5,800 observations of monarch butterflies. This winter, the partnership of universities, agencies and other organizations called Monarchs Overwintering in Southeastern States is requesting the public’s continued involvement in reporting sightings.
Sonia Altizer, a University of Georgia ecology professor and director of Project Monarch Health, said the information can help scientists determine if these iconic but declining butterflies “can overwinter as non-breeding adults in the southern U.S. and how this might affect future population numbers.” The monitoring will also help document how winter-breeding activity might be affecting the annual migration to Mexico.
Understanding migration and overwintering behavior is crucial to conserving monarchs, a candidate for listing under the Endangered Species Act.
Thousands of monarchs stream across the South each fall on their way to wintering grounds in central Mexico. In the spring, this eastern population of the butterfly returns to the U.S. and Canada to breed.
But not all monarchs migrate to Mexico. Volunteer observations over the past two decades have helped scientists better understand how and why some monarchs breed throughout the winter in the southern U.S. Scattered reports also suggest that some monarchs can overwinter in coastal regions in a non-breeding state, similar to their wintering behavior in Mexico.
The public is encouraged to report monarch sightings from Dec. 1-March 1 in North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana and Texas.
Susan Meyers, cochair of Monarchs Across Georgia, agreed. “Volunteers are vital to this effort. If you enjoy being outdoors and exploring your local ecosystem, this is an easy activity that can be done alone or with your family.” How to take part: • Step 1: Create a free account at journeynorth.org/reg. • Step 2: Learn how to report monarch sightings at journeynorth. org/monarchs. • Step 3: From Dec. 1-March 1, submit monarch observations at journeynorth.org/sightings.
