Fraxinus nigra
Also called Swamp Ash, Water Ash, Brown Ash, Hoop Ash
Fraxinus nigra, or the 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 2017 the species is threatened with near total extirpation throughout its range within the next century as a result of infestation by an invasive parasitic insect known as the emerald ash borer (Agrilus planipennis).
Black ash commonly occurs in swamps, often with the closely related green ash. Its fall foliage is yellow. Black ash is one of the first trees to lose its leaves in the fall. It is very closely related to Manchurian ash, and will easily hybridize with it. Some consider the two to be geographic isolates of each other.
