Editing Northern flying squirrel (section)

==Habitat and range==
The northern flying squirrel is found in [[coniferous]] and [[mixed coniferous forest]]s across the top of North America, from [[Alaska]] to [[Nova Scotia]], south to the mountains of [[North Carolina]] and [[Tennessee]] and west to Utah. The [[Humboldt's flying squirrel]] was formerly considered conspecific, but was found to be a [[cryptic species]], and now considered distinct. It is generally smaller and darker than northern flying squirrel and occurs in British Columbia, northern California, Washington and Oregon.

Two [[subspecies]] are found in the southern [[Appalachians]], the Carolina northern flying squirrel, ''G. s. coloratus'', and the West Virginia northern flying squirrel ''G. s. fuscus'', both of which are [[endangered]], although the West Virginia subspecies has recovered enough that it was delisted in August 2008.<ref>{{Cite web |url=http://ecos.fws.gov/tess_public/DelistingReport.do |title=USFWS Delisting Report dated 8/09 |access-date=2009-08-27 |archive-url=https://web.archive.org/web/20070728035106/http://ecos.fws.gov/tess_public/DelistingReport.do |archive-date=2007-07-28 |url-status=dead }}</ref><ref name=delisting/>

The U.S. Fish and Wildlife Service temporarily put the West Virginia northern flying squirrel back under protection on June 6, 2011, in response to a court order.  On appeal, the delisting was reinstated in March 2013.<ref name=delisting>{{cite web |title=Federal Register |url=https://www.govinfo.gov/link/fr/78/14022?link-type=pdf |website=govinfo.gov |access-date=6 December 2019 |date=4 March 2013}}</ref>

''G. s. californicus'', the San Bernardino flying squirrel, is found in the San Bernardino National Forest in California.<ref name=":0">{{cite web |title=San Bernardino Flying Squirrel (Glaucomys sabrinus californicus) {{!}} U.S. Fish & Wildlife Service |url=https://www.fws.gov/species/san-bernardino-flying-squirrel-glaucomys-sabrinus-californicus |access-date=18 October 2023 |website=FWS.gov |language=en}}</ref> In 2010, the [[Center for Biological Diversity]] petitioned the U.S. Fish and Wildlife Service to give the San Bernardino flying squirrel protections as an endangered species, but ultimately their request was denied.<ref name=":1">{{cite web |date=5 April 2016 |title=Federal agency declines to list San Bernardino flying squirrel as endangered |url=https://www.sbsun.com/2016/04/05/federal-agency-declines-to-list-san-bernardino-flying-squirrel-as-endangered/ |access-date=21 October 2023 |website=San Bernardino Sun}}</ref>  The U.S. Fish and Wildlife Service said, "in a thorough status review of the species using the best available science, the Service has found that the squirrel is abundant where it is found and that the threats to habitat loss from urban development, [[habitat fragmentation]], wildfire, urban air pollution and climate change do not pose significant threats to its long-term survival.".<ref name=":1" /> The Center for Biological Diversity argues that temperature changes are reducing the San Bernardino flying squirrel's forest habitat and negatively affecting the availability of the truffles it feeds on, with urban development impacting the area as well.<ref>{{cite web |title=San Bernardino flying squirrel |url=https://www.biologicaldiversity.org/species/mammals/San_Bernardino_flying_squirrel/index.html |website=www.biologicaldiversity.org}}</ref>
