Previously, if the ⫴ hairs are small (visible only through a good 🔎︎ hand-lens), this was called variety/​subspecies green ash, Fraxinus pennsylvanica var. lanceolata and subintegerrima.  But current observations and thinking find no strong distinction.

Regardless, this tree is (these trees are) part of ash  genus Fraxinus in ash / lilac / olive  family Oleaceae.

Formerly abundant, in much of its range, this tree (along with other native ash trees), with stem diameters ⌀ > 2½ cm (1 in) (taller than a 🏀︎ basketball hoop or so), have been or are now being killed by parasitic insect emerald ash borer (EAB)  Agrilus planipennis.

We know some homeowners, who for over a decade protect their six adult ash trees through annual treatments.  And on a larger scale, we have heard that some communities do the same.  We have no details on this treatment, but we could find out.
