Western Monarch Call to Action

Western monarchs need everyone’s help. It is estimated that in the 1980s, at least 4.5 million butterflies migrated to the Pacific coast annually. In 2018, the annual Xerces Western Monarch Thanksgiving Count showed that the population hit a new low, less than 29,000 butterflies—a loss of more than 99% since the 1980s.

This Western Monarch Call to Action, led by the Xerces Society for Invertebrate Conservation, aims to provide a set of rapid-response conservation actions that, if applied immediately, can help the western monarch population bounce back from its extremely low 2018–19 overwintering size. Long-term conservation effort is needed to rebuild the western population of monarchs. The goal of this call to action is to identify actions that can be implemented in the short-term, to avoid a total collapse of the western monarch migration and set the stage for longer-term efforts to have time to start making a difference.
