White Ash
Fraxinus americana, the white ash or American ash, is a fast-growing species of ash tree native to eastern and central North America. The tree is highly valued as lumber.
The white ash population in North America was devastated by the invasive emerald ash borer, which killed hundreds of millions of them as it spread during the 1990s–2010s. Surviving white ashes are often much younger, with the oldest and tallest white ashes largely becoming dead trees due to the emerald ash borer.
The name white ash derives from the glaucous undersides of the leaves. It is similar in appearance to the green ash, making identification difficult. The lower sides of the leaves of white ash are lighter in color than their upper sides, and the outer surface of the twigs of white ash may be flaky or peeling. Green ash leaves are similar in color on upper and lower sides, and twigs are smoother. White ash leaves turn yellow or red in autumn. Despite some overlap, the two species tend to grow in different locations as well; white ash is a forest tree that commonly occurs alongside sugar maple while green ash is a pioneer species that inhabits riparian zones and disturbed areas. The white ash's compound leaves usually have seven leaflets per leaf whereas the counts in other ash trees more often vary.
Like other species in the section Melioides, Fraxinus americana is dioecious, with male and female flowers produced on separate individuals.
The C-shaped leaf scars of white ash are useful in distinguishing this species from the closely related green ash (Fraxinus pennsylvanica). The lateral buds of F. pennsylvanica share a less curved margin with their corresponding leaf scars, imparting an overall D shape to the latter.
The species is native to mesophytic hardwood forests from Nova Scotia west to Minnesota, south to northern Florida, and southwest to eastern Texas. Isolated populations have also been found in western Texas, Wyoming, and Colorado, and the species is reportedly naturalized in Hawaii.
There are an estimated 8 billion ash trees in the United States – the majority being white ash trees and green ash trees.
White ash is one of the most used trees for everyday purposes and, to keep up with high demand, is cultivated almost everywhere possible. The wood is white and quite dense (within 20% of 670 kg/m3), strong, and straight-grained. Its species produces an ideal, atypical dominant excurrent structured crown. It is a traditional timber of choice for production of baseball bats and tool handles. The wood is also favorable for furniture and flooring. A study compared it to eight other different species, and it showed the highest antibacterial activity in the context of manufacturing chopping boards.
Woodworkers use the timber mainly for interior uses due to high perishability in contact with ground soil. It is also used to make lobster traps. Since the 1950s, it has also become a popular choice for solid electric guitar bodies. It makes a serviceable longbow if properly worked. The wood was used in ceiling fan blades from the 1970s through the mid-1980s, though cane was sometimes simulated with plastic then. It is no longer used for ceiling fan blades in most countries.
