Summary

By the Congressional Research Service (Introduced in House, Jan 3, 2025). Public domain.

This bill requires naturally propagated animals (i.e., wild animals) and artificially propagated animals to be treated the same under the Endangered Species Act of 1973 (ESA).

Specifically, distinctions between naturally propagated animals and artificially propagated animals may not be made when the federal government makes determinations under the ESA, such as determinations to designate endangered species, threatened species, or critical habitats.

In addition, the bill requires the U.S. Fish and Wildlife Service and the National Marine Fisheries Service to authorize the use of artificial propagation of animals of a species when mitigation is required under the ESA.

This bill applies to all endangered or threatened species regardless of when they were listed as endangered or threatened.
