American elms succumbed to the Dutch elm disease in 1970s, consequently maples and ash dominate the urban landscape, and account for more than 40% of Wisconsin’s urban forest. And history tends to repeat itself; to this end, an invasive insect called Emerald ash borer (EAB) now threatens ash trees in North America. EAB is an exotic insect (beetle) from Asia and was first discovered in southeast Michigan in 2002. Since its discovery, the beetle has destroyed more than 50 million ash trees in the Midwest region, including Wisconsin in 2008.
