Wikipedia Abstract

Fraxinus nigra (black ash) is a species of ash native to much of eastern Canada and the northeastern United States, from western Newfoundland west to southeastern Manitoba, and south to Illinois and northern Virginia. Formerly abundant, as of 2014 the species is threatened with near total extirpation throughout its range, as a result of infestation by a parasitic insect known as the emerald ash borer.

Usage [3]  Logs of wood can be beaten with mauls to separate the growth layers, these layers can then be cut into strips and woven into baskets; A blue dye can be obtained from the bark; Wood - not strong, rather soft, durable, heavy, tough, coarse-grained, easily separated into thin layers. It weighs 39lb per cubic foot. Largely used for making furniture, cabinet making, interior finish and veneer; The wood makes a good fuel, it does not crackle or shoot sparks like many other woods; If the wood is soaked in water and then pounded, it separates easily into thin sheets; These sheets have then been used to make woven baskets, barrel hoops, chair seats etc;
