Proclaims July 14-18, 2025 as California Western Monarch Protection Week to raise public awareness and promote conservation efforts

Western monarch butterfly populations have declined 81% over the past quarter century, from 1,235,490 to 233,394 monarchs

Population decline attributed to loss of breeding, migratory, and overwintering habitat, climate change, and herbicides/insecticides harming milkweed

California has sought to protect over 400 western monarch butterfly overwintering sites across the state, including Pacific Grove Monarch Sanctuary and Natural Bridges State Beach

U.S. Fish and Wildlife Service proposed protections in 2024 including designation of over 4,300 acres in California as critical habitat
