In 2016, the Sierra Nevada red fox was considered for protection as a threatened or endangered subspecies under the Endangered Species Act, but was denied due to lack of information. Mother fox's will create a maternity den to raise their young in that will be lined with grass and leaves in a safe location. This species is experiencing greater conservation threats at the southern edge of its range, so efforts to provide habitat in Oregon are especially beneficial. Fire suppression reduces available habitat in some high-elevation areas. McFadden-Hiller, J.E. The Sierra Nevada red fox has been added as a “strategy species” in the 2015 draft update of the Oregon Conservation Strategy after ongoing studies found the rare species in the Mt. Jefferson, Mt.
