Unfortunately, it is highly susceptible to the destructive emerald ash borer forcing cities once again to cut down and replace them. biggest threats to the survival of Green Ash and other Fraxinus larvae of the wood-boring beetles Tylonotus bimaculatus Very similar to both Black Ash (Fraxinus nigra) and White Ash (F. americana), Green Ash can easily be distinguished from the other two by its short, winged stalks on the leaflets. are odd-pinnate with 5-9 leaflets (usually, there are 7), spanning Black Ash can have similar bud scars but there is always a measurable internode (gap) between the terminal bud and the first two lateral buds below it. The trunk is normally straight and upright, forming a thick layer of gray bark with interlaced ridges that form narrowly diamond-shaped cavities.
