Preble's Mouse Delisted In Wyoming, But Not Colorado

Laramie, WY – The US Fish and Wildlife Service is proposing to remove the Preble's meadow jumping mouse from the endangered species list in Wyoming, but keep it as a threatened species in Colorado.

The acting director of Fish and Wildlife for this region, Steve Guertin says his researchers got access to private land, and that gave them better data.

New information indicates to us that the Preble's populations in Wyoming are much more widely distributed than we assumed at the original time of listing.

The mouse was first listed as an endangered species in 1998. The listing was controversial because only genetic testing can distinguish the Preble's mouse from other, more common mice.

This latest proposal from Fish and Wildlife stems from a lawsuit filed by Wyoming in January. In a settlement, the Fish and Wildlife Service agreed to make a delisting decision by the end of November.
