The U.S. Fish and Wildlife Service revised the 2005 proposed rule to delist the Preble’s meadow jumping mouse (Zapus hudsonius preblei). It proposed to amend the listing for the Preble’s meadow jumping mouse to specify over what portion of its range the subspecies is threatened.
The best scientific and commercial data available demonstrates that:
The Preble’s meadow jumping mouse is a valid subspecies and should not be delisted based upon taxonomic revision; the subspecies is not threatened throughout all of its range; and the portion of the current range of the subspecies located in Colorado represents a significant portion of the current range where the Preble’s meadow jumping mouse is likely to become endangered within the foreseeable future, and the subspecies in that portion of its range should retain its threatened status.
