Natural History Wanderings

The Western Monarch Thanksgiving Count (also known as the WMTC) is the longest running and most comprehensive effort to monitor overwintering monarchs in California. During a designated three-week period centered on Thanksgiving, volunteers count the butterflies and assess the condition of the habitat they rely on. There are currently 299 sites that are part of the WMTC with between a third and two-thirds of those sites monitored in any single year. Visiting one to two hundred sites over five hundred miles of coast in a three-week period is no easy feat, and it takes the efforts of over a hundred volunteers. To learn more or participate go to Western Monarch Thanksgiving Count
