Black ash

Black Ash (Fraxinus nigra) is a species of ash tree native to much of eastern and central North America. It is also commonly known as swamp ash due to its preference for wet, swampy conditions.

Description

The Black Ash is a medium-sized deciduous tree that typically grows to a height of 15–20 m, with a trunk diameter of up to 60 cm. The bark is grey, with deep furrows and flat-topped ridges. The leaves are 15–30 cm long, with seven to eleven leaflets. The flowers are small and purplish, produced in clusters in the early spring. The fruit is a samara 2.5-4.5 cm long, with a winged apex.

Distribution and habitat

Black Ash is found in the northeastern United States and eastern Canada. It is most commonly found in wetlands, swamps, and along streams and rivers. It is tolerant of poor drainage and frequently grows in water-logged soils.

Uses

The wood of the Black Ash is used for a variety of purposes, including furniture, paneling, flooring, and tool handles. It is also used in the manufacture of baskets, due to its ability to be split into thin strips. The tree's bark has been used in traditional medicine by Native American tribes.

Conservation status

The Black Ash is threatened by the emerald ash borer, an invasive insect species from Asia. Efforts are being made to protect existing populations and to develop resistant strains.
