This bill amends the Endangered Species Act of 1973 to significantly restrict its scope and the use of associated financial assistance. It prohibits the Secretary from listing any species as endangered or threatened if that species is not native to the United States, thereby focusing federal protection efforts exclusively on indigenous species. Furthermore, the legislation modifies provisions for international cooperation by explicitly forbidding the use of financial assistance provided under the Act for acquiring lands, waters, or other interests in a foreign country . This ensures that U.S. funds are not utilized for land acquisition purposes abroad under the Act, reinforcing a domestic-centric approach to species protection and resource allocation.
