This lawsuit aims at ESA protection for 9 species, one of which is the San Bernardino flying squirrel, a subspecies of the northern flying squirrel that lives at high elevations in the San Bernardino and San Jacinto Mountains of southern California. According to the USFWS, it is “believed that the San Bernardino flying squirrel represents ancestral populations that have been isolated in forested, higher elevation refugia by a warming climate” (since the last ice age). And “The [CBD] petition states that high-elevation species have limited suitable habitat for movement in response to these [more recent] climate-caused shifts in habitat, and may simply run out of suitable habitat to occupy.”
Also involved: “two distinct populations of the black-backed woodpecker.”
However, the IPCC says, “Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped.” (IPCC, 2013: Summary for Policymakers. In: Climate Change 2013: The Physical Science Basis.) So much for the squirrel. But maybe climate change will bring more fires, and thus more snags, which will benefit the black-backed woodpecker.
