Ash Resource - Emerald Ash Borer. USFS NA Forest Health Protection

The emerald ash borer has been found infesting green, black and white ash. In the Upper Midwest, ash (genus Fraxinus ) trees are common in the urban landscape along streets, in yards and in woodlots. Green ash dominates the urban ash resource. In forest landscapes, ash tends not to be an abundant tree but can be locally very common. From a wood products standpoint, white ash is the most valuable species. Black ash is common in forested wetlands.

This page provides information on ash identification and range maps of our native ash species. It also provides background information on the ash resource in urban areas versus more rural forested areas.
