Fewer than 2,000 western monarch butterflies overwintered in California in 2020, an alarming 99.9% decline since the 1980s.

Climate change is responsible for storms and drought that are disrupting monarch migration patterns, and loss of habitat across their migration corridors places western monarchs at critical risk of extinction unless we adopt an all-hands approach to save them.

River Partners is already working with a strong coalition of scientists and conservation partners to reintroduce monarch habitat at the largest coordinated scale in the western U.S.

The restoration of river corridor habitat is a leading strategy to boost monarch populations and save them from extinction. River Partners is taking a two-pronged approach to rapidly reintroduce monarch habitat:

With a group of dedicated public agency and nonprofit partners, we are planting nearly 600 acres of milkweed — essential to the monarch’s life cycle — and other monarch-friendly plants along rivers and streams in eight critical sites across California. River Partners is coordinating planting and monitoring in partnership with California Department of Fish and Wildlife, Great Valley Seed Co., Environmental Defense Fund, The Xerces Society, and Dr. Cheryl Shultz, Washington State University.

River Partners is sourcing large quantities of additional seed and plants to add milkweed and other nectar-rich natives to our other restoration sites statewide. Planting milkweed and other native plants along river corridors is a key strategy for restoring monarchs, and supports other at-risk species up and down the food chain.
