The ash tree is a common name for a variety of trees in the genus Fraxinus. These trees are part of the olive and lilac family, Oleaceae. Ash trees are native to several regions across the world, including Europe, Asia, and North America.

Description

Ash trees are deciduous, shedding their leaves annually. They are known for their tall, straight trunks and compound leaves, which are made up of multiple leaflets. The bark of an ash tree is typically a pale grey color, with a rough texture.

Species

There are approximately 65 species of ash trees. Some of the most well-known include the Fraxinus excelsior or European ash, the Fraxinus americana or white ash, and the Fraxinus pennsylvanica or green ash. Each species has its own unique characteristics and habitat preferences.

Uses

Ash wood is known for its strength and elasticity, making it a popular choice for tool handles, furniture, and sports equipment. In addition, the tree's seeds, known as "ash keys", have been used in traditional medicine and as a food source.

Threats

Ash trees are currently under threat from a variety of pests and diseases. The most significant of these is the Emerald Ash Borer, a beetle native to Asia that has caused widespread damage to ash populations in North America.

Conservation

Efforts are underway to conserve ash trees and to develop resistant varieties. These include breeding programs and the use of biological control agents against pests.
