The U.S. Fish and Wildlife Service is designating more areas as critical habitat for the threatened Preble's meadow jumping mouse. Some of the land re-designated impacts those in El Paso and Teller Counties.

The agency said Tuesday that it will add 177 miles of rivers and streams and about 22 square miles in Colorado to the designated area. Overall, about 411 miles of rivers and streams and 54 square miles in seven counties will be considered critical habitat, which could require special management to protect the mouse.

The areas include land and waters in Boulder, Broomfield, Douglas, El Paso, Jefferson, Larimer and Teller counties.

The Fish and Wildlife Service says the economic impacts of the designation could be $2.66 million to $5.98 million per year over the next 20 years, mostly related to potential effects on development projects.
