This bill proposes significant amendments to the Endangered Species Act of 1973 , primarily focusing on the treatment of artificially propagated animals. It mandates that the Secretary, when making any determination under the Act, shall not distinguish between naturally propagated and artificially propagated animals, ensuring equal treatment for both. Furthermore, the bill requires the Secretary to authorize the use of artificial propagation for mitigation purposes whenever such mitigation is required for a species under the Act. These changes are designed to apply broadly, affecting all species regardless of their listing status date, whether before, on, or after the bill's enactment.
