American Sovereignty and Species Protection Act of 2025

This bill amends the Endangered Species Act to prevent federal protection for nonnative species and restrict conservation funding. Specifically, it blocks the U.S. Fish and Wildlife Service from listing nonnative species as endangered or threatened under Section 4(a), and prohibits using federal funds to acquire land in foreign countries for conservation under Section 8(a). It directly affects the administration of the Endangered Species Act and conservation organizations working with nonnative species or international land acquisitions. The key changes are a categorical exclusion of nonnative species from protection and a ban on foreign land purchases using federal conservation funds.
