Monarch Butterfly in Crisis

The Monarch Butterfly is unprotected. It is not on an endangered species list and there is no Federal or State protection in the pipeline.

This spring, we have some unfortunate news to share about the Monarch butterfly population. The overwintering numbers of western Monarchs dropped again this year, to a total of only 1,914 monarch butterflies. That’s a 99% decline since the 1980’s. The Monarch butterflies that migrate along the West coast and West of the Rockies, spend the winter months in Southern California. “In only a few decades, a migration of millions has been reduced to less than two thousand butterflies,” said Stephanie McKnight, a conservation biologist with the Xerces Society who helps coordinate the counting of the Western populations.

The Eastern Monarch population fell this winter as well – a 26% decrease from the previous year. The Chart shown here represents the Monarch butterfly overwintering numbers in Mexico, which are measured in hectares (areas covered).

Dr. Karen Oberhauser, director of the UW–Madison Arboretum, writes, “I have been studying and working to conserve monarchs and their habitat for over 35 years. This announcement, while not unexpected based on the numbers that we saw in the Upper Midwest last summer, is a reminder that we can’t rest in our efforts to conserve monarchs.” Other than plant Milkweed like crazy, which so many of you are doing already, you can urge the following groups in your community to create milkweed/monarch/pollinator habitat and promote the conservation of monarchs and other pollinators:

⁃ Girl Scouts, Boy Scouts, Future Farmers of America, and 4-H
⁃ Garden clubs, horticultural societies, Master Gardeners, Master Naturalists
⁃ Administrators of city gardens and parks
⁃ Garden centers, Landscaping firms, and businesses sensitive to their public image

Also, support organizations whose mission is aligned with native landscaping, and who’s work increases Monarch and pollinator habitat:

Wild Ones
Native Plant Societies
– Preservation and conservation organizations
– Land trusts

The Xerces Society website has a call to action page for the western Monarchs.
