A Quick Guide to Monarch Habitat on Farms in California’s Central Valley

By Angela Laws, Sarina Jepsen, Jessa Kay Cruz, Aimée Code, Stephanie McKnight, Emma Pelton, Samantha Marcum, and Scott Hoffman Black.

Monarch butterflies and their milkweed host plants have historically been common throughout California. Over the past few decades, however, monarch populations across the United States have declined. The western population is now less than 1% of its size in the 1980s. In California, monarch butterflies overwinter along the coast, then migrate inland to spend the spring and summer breeding throughout the state, as well as other parts of the western U.S. The Central Valley is an important part of this breeding range. This guide provides information for farmers in the Central Valley interested in adding monarch habitat to their farms.
