In this episode of ID That Tree, meet the ash family, with specific focus on the white ash, which is typically found on higher and drier sites than its cohorts. This species, which is in trouble due to the emerald ash borer, an invasive beetle, features opposite leaf arrangement, compound leaves with seven to nine leaflets, and squatty terminal buds as well as a bud that dips down into the leaf scar, resembling a smiley face. The bark is gray and featured an interlacing network of ridges forming a diamond shape.
