Found in low wet areas.

Formerly abundant, in much of its range, this tree (and other native ash trees), with stem diameter over 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.

Although 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.

And we heard that our local tribe is growing out thousands of black ash 🌱︎ seedlings.  We have no details on what the tribe plans to do with these seedlings, nor why they think they will survive, but we could find out.
