The Monarch Action, Recovery, and Conservation of Habitat Act of 2025, also known as the MONARCH Act, aims to protect and sustain the western population of monarch butterflies, which is facing a serious risk of extinction. The legislation seeks to address the drastic decline in their numbers, which has fallen by over 99 percent in the past three decades due to various environmental challenges. Key provisions of the Act include the establishment of the Western Monarch Butterfly Rescue Fund, which will provide financial support for conservation projects.
