Smoky Mountain Monarch Migration

MonarchTaggingByWarrenBielenberg-e1509738109435-300x210Monarch butterflies migrate south each summer and spend their winter hibernating in parts of Southern California and Mexico where the climate is warm year-round. Monarchs living east of the Rocky Mountains migrate to Mexico overwintering in Oyamel Fir trees. Monarchs living west of the Rocky Mountains overwinter in Pacific Grove, California in eucalyptus trees. The butterflies return to the same trees each year which is unusual because the same butterfly never makes the trip twice and yet, somehow, the fourth generation of Monarchs find the right tree!  Amazingly this fourth generation migrates over 2,500 miles each year for the perfect hibernation climate and tree.

The Great Smoky Mountains Institute at Tremont monarch butterfly tagging program is an effort to monitor the health of the Monarch population and to track the butterflies progress along their migration route. Each year in late summer and early fall volunteers flock to Cades Cove in the Great Smoky Mountains Tagging program. Part of the fun is discovering, months after the event, that the butterfly you tagged was located thousands of miles away.
