Bark stripping has been linked to several squirrel species in North America including eastern gray (Sciurus carolinensis) and fox (S. niger) squirrels as well as two so-called pine squirrels; the red squirrel (Tamiasciurus hudsonicus) and Douglas pine squirrel (T. douglasii). Gray squirrels target a wide range of deciduous trees although the past damage I’ve observed in Greater Cincinnati has primarily occurred on American beech, honeylocust, and maples. As with other areas of the country, bark stripping usually occurs in our region from April through early July. Thankfully, bark stripping by squirrels remains somewhat rare in North America.
