Description wikipedia

The northern Idaho ground squirrel (Urocitellus brunneus) is a species of the largest genus of ground squirrels. This species and the southern Idaho ground squirrel were previously considered conspecific, together called the Idaho ground squirrel. The species is about 233 mm in length and weighs 120 to 290 grams. The northern Idaho ground squirrel has sexual dimorphism and a dark-reddish gray coat. The squirrel hibernates for 8 months and lives in dry meadows in Adams and Valley Counties in western-central Idaho. They eat forbs, grasses, shrubs, trees, rushes, and sedges. The mating season occurs within two weeks from the start of the active period and lasts about 12–13 days. Females only have one litter per year, and there are about five weaned babies per litter, which leave the burrow around late March-early April. In 2000, the species was classified as threatened under the Endangered Species Act mostly due to habitat loss. There are about 2000 individuals remaining, but the population is increasing resulting from conservation efforts. A recovery plan for the species was put in place by the U.S. Fish and Wildlife Service in 2003 and forest restoration for the species is anticipated to be done by 2027.
