The MONARCH Act addresses the imminent risk of extinction facing western monarch butterflies due to habitat loss and climate change. It establishes the Western Monarch Butterfly Rescue Fund to provide grants for conservation projects and mandates annual reports on project statuses. The Act defines terms like 'conservation' and 'western monarch butterfly.' It also allocates funds for administrative expenses and the implementation of the Western Monarch Butterfly Conservation Plan. The Act aims to restore native habitats and ensure the survival of western monarch butterflies, critical for pollination services and conservation of other essential pollinators.
