The U.S. Fish and Wildlife Service will still list the Preble's meadow jumping mouse as threatened in Colorado and Wyoming.
The announcement today came in response to three petitions seeking a delisting.
The mouse's status as a threatened species led the government to designate 31-thousand acres this summer for protection as habitat,
prompting lawsuits by the city of Greeley and the Mountain States
The decision to continue listing the mouse as threatened doesn't take into account new research by Rob Roy Ramey the Second, whose team says the Preble's mouse is not a distinct subspecies.
The Fish and Wildlife Service says that research wasn't available when it made its decision.
