The act directs the Secretary of the Interior to reissue a final rule that removes the Greater Yellowstone Ecosystem population of grizzly bears from the federal endangered and threatened wildlife list. Reissuance must occur within 180 days of the bill’s enactment and is exempt from any judicial review, ensuring the decision is final and unchallengeable. This change effectively delists the grizzly bear population in that region, altering conservation status and potentially impacting management practices. The bill’s purpose is to streamline the delisting process and remove legal obstacles that could delay the removal of the species from the list.
