Northern Flying Squirrel Listed as State Endangered Species

Earth Times

Commissioners today gave final approval to add to the state’s endangered species list the northern flying squirrel, which is the larger and rarest of Pennsylvania’s two flying squirrel species.

“Our field survey work has shown that the northern flying squirrel’s population has been in decline for some time and is in need of our assistance,” said Greg Turner, Game Commission biologist.  “They have very specific habitat preferences and their existence in Pennsylvania is threatened by a parasite carried by southern flying squirrels and by forest pests that destroy their preferred habitat.  Adding this species to the state’s endangered species list will allow us to ratchet up the management attention we provide these squirrels.  Also, their eligibility for federal funding will improve.”

Northerns were once found across Pennsylvania’s northern tier. The major reason for their decline is the loss and fragmentation of older-growth coniferous forest in Pennsylvania. Now their small local populations are threatened by additional limiting factors

The northern flying squirrel is common in the boreal forests of states along the Canadian border and Canada.  In Pennsylvania, however, its distribution is limited to less than a half-dozen known sites in old-growth forests with a large percentage of conifers. All are in northeastern Pennsylvania, with the exception of one in Warren County and one in Potter County. It’s possible there are more local populations, but they haven’t been uncovered yet. Identification isn’t easy either, because they are very similar to southern flying squirrels.

Northern flying squirrels have been identified as a species of greatest conservation in Pennsylvania’s Wildlife Action Plan, which was adopted by the agency and approved by the U.S. Fish and Wildlife Service in 2006. Their plight is considered a “high-level concern.” The Game Commission several years ago also approved a project through the State Wildlife Grant Program that focused on developing an annual statewide nest box survey and identifying the habitat preferences of northerns through telemetry. It was carried out by Wilkes University and Penn State University.

The parasite carried by southern flying squirrels and lethal to northerns is called Strongyloides robustus. The parasite poses no threat to southerns, but it seems to suppress the northerns’ ability to put on winter fat, and to even maintain its existing weight. Since northerns and southerns will share living quarters where their ranges overlap, there is substantial concern for the already rare northerns.

Further complicating the northerns’ existence is the wooly adelgid, a European insect that strips and frequently kills hemlock trees, which northerns prefer as habitat. The forest pest has devastated and continues to ravage huge chunks of hemlock forestland throughout eastern Pennsylvania.

  1. Bravo to the state of Pennsylvania for caring about this important variety of squirrel – little seen because of its nocturnal activity but nonetheless important as a contributor to the forest ecology. Now if only we could stop that deforestation.

    Hats off to fellow researchers studying the Northerns. As a research student at Penn State, studying S. robustus under the supervision of Dr. Carolyn Mahan, it’s awesome to see the state of Pa understanding the need for putting N. Flying Squirrels on the endangered species list…

    • I moved here, in northern Pa. last AUG.,”20 miles north of the Blue Mountain”. Last winter I started putting bird food out. One night I was out after dark and discovered some sort of small animal hopping up my spruce tree. In no time it was about three feet away from my feet. I had a flashlight shinning on it trying to figure out what it was,what Big eyes, but when it saw my shoes it left in a hurry. I don’t think it came back to the tree for a while in the hours I want out after dark. But anyway, the next day I got on the computer and discovered it was a flying squirrel. A few months later it started showing its-self, so I would talk to it. In this point of time it got to know me well. The other night, Nov 26th, 2011″ puffy”, his name, brought two friends with him. I now talk to all of them. They seem to like to hear me talk. My Question to you is, how can I determine if” puffy” and his friends are the Southern Or the Northern squirrel?

      I think your idea of saving the flying squirrel is good because helping animals is good for the environment. animals can produce more healthy plants like eating the dead plants to make new ones. Then after the flying squirrel is saved it can not be endangered any more then they can be more common to the world. If the flying squirrel is common to the world sciencetist can do more research on them. I think that the researchers dont have the full research on the flying squirrel. If you like this/ email me at nathanacree@gmail.com if you think my comment is good.

    I am doing research on Flying Squirrels and I was wondering where the author got the information about stronglyoides affecting the ability for northerns to store winter fat. I was just wondering if this was in a scientific article so I could include it in a research paper.

    To tell northern and southern flying squirrels apart, look at their stomachs. Southerns have an all white belly while northerns have a grayish belly. Most likely the flying squirrel is a southern
