How cool about the flying squirrels!CygnusX1 wrote: what other trees are prominent in your area?
Other prominent trees in my area are the Aspens that you mentioned, maples, weeping willows, Russian olives, cherry, pear, apple, and many that I don't know the names of. There are lots of evergreens (pines, and blue spruce in particular). My yard also has elms (weeds, basically), a "horse chestnut", ash, peach, one of the aforementioned pines, and a couple of other weedy trees that I don't know what they are.
