MONARCH Act of 2025

S 2128, the MONARCH Act of 2025, establishes a $12.5 million annual fund to support conservation efforts for the western monarch butterfly, which has declined by over 99% in 30 years and faces imminent extinction. The bill creates a grant program providing funding for projects led by local governments, tribal entities, or nonprofits - focusing on restoring milkweed, nectar plants, and habitat across California, Arizona, Nevada, Washington, Oregon, Idaho, and Utah. Grants require project proposals demonstrating clear potential to aid monarch recovery, with mandatory reporting to the public and state legislatures on progress. The law also mandates annual reports to Congress on project outcomes and the implementation of a conservation plan developed by wildlife agencies.
