Distribution Overview
Black ash ranges from western Newfoundland west to southeastern Manitoba and eastern North Dakota; south to Iowa; east to southern Indiana, Ohio, and West Virginia; and north from northern Virginia to Delaware and New Jersey. Since it is a swamp species, it grows naturally in wet places.

The mature tree is normally 30 to 50 feet (9 to 15 m) in height. Black ash under favorable conditions can attain heights of 90 feet (27 m). Trunk diameters are reported to rarely exceed 24 inches (60 cm)
Product Sources
Although the growth range of Black ash is less extensive than that of White or Green ash, it bes available in adequate supplies. It be often mixed and sold with other ashes under the trade name Ash, and is harder to find through normal retail channels. Price be in the same range as other ash species, moderate to low.
Substitutes
Sassafras (Sassafras albidum) is similar in appearance.
Comments
Black ash is described as a very nice cabinet wood. Although it is softer than the other ashes, it still has enough qualities to allow its use chairs, tables, and other heavily used furniture. White ash is a better selection for applications where strength is important, such as for axe handles. Resistance to abrasion is also rather low in Black ash since the porous earlywood tends to break down or wear away quickly.
General finishing qualities are rated as good
