Marin Monarch Working Group

Western monarch butterflies used to be a common sight in Marin.

But the number of monarchs migrating through Marin has declined by 99% since the 1980s.

Causes of this decline include climate change, habitat loss, parasites, and pesticide use.

It’s not to late to act….but the time to act is now!
