This species is not as frequent as the white ash but in certain habitats it is a common tree. I am certain that I have seen this species as far north as Yellow River in Marshall County but I was not able to collect a specimen.

Deam (1932): In the original forest the pioneers called the very large specimens of ash with deeply furrowed bark "the old fashion" ash. It is believed that most of these specimens were of this species. In the hilly parts of Indiana this species is found in situations too dry for the white ash, and for this reason should be given preference in hillside planting. On the wooded bluff of White River in Fairview Park north of Indianapolis is a specimen that measures 31 dm in circumference, b.h. The deepest furrows on the north side of the tree are 6 cm. deep.
This species ... is known in the trade as white ash. Mr. Beadle who first recognized the species, named it Biltmore ash in honor of the Biltmore Estate on which the tree was first discovered. On the Clark County State Forest is a planting of sixteen-year-old white ash in which are mixed with quite a number of Biltmore ash. This species at a distance can be distinguished from the white ash by the rougher bark of the trunks and the darker green color of its foliage, and in the autumn by its more colorful foliage. A closer view shows that the leaflets of the Biltmore ash stand in a plane above the rachis, higher than those of the white ash. The wood is not commercially distinguished from the white ash but its mechanical properties rank it somewhat below that species.
