In coming years, these shiny green Emerald Ash Borer (EAB) beetles will be a death sentence for many of Baltimore’s ash trees, which make up almost a tenth of our urban forest. However, some Midwestern cities find it far more cost effective to save mature ash trees in all their glory than to pay for their removal.

A shiny winged insect the size of a penny, the EAB is thought to have arrived in the United States in solid wood packing material from its native Asia. First detected in the Detroit, Michigan/Windsor, Ontario area in July 2002 and then in Ohio, infestation by EAB has already killed tens of millions of ash trees in the central and northeastern United States.

In August of 2003, Maryland became the third state to detect EAB. That month, state inspectors found the Emerald Ash Borer on some of 121 ash trees at a landscape nursery in Prince George’s County. Despite measures to eradicate the pest, in 2008, EAB beetles showed up in Charles County. By 2011, EAB had been detected in several more counties— Anne Arundel, Howard, Allegany, and Washington. At first, states tried to prevent EAB spreading by cutting down all nearby ash trees where EAB might breed. But now many cities have a mixed approach—cut down infested trees, but save and protect large and beautiful specimens by pesticide injections.

Now, as long expected, the Emerald Ash Borer is here in Baltimore. City Forestry, TreeBaltimore and its non-profit partners haven’t planted ash for some years now, but ash is one of the more common trees in Baltimore, 212,000 trees or 8.6 percent of our total urban forest. Of our approximately 100,000 street trees,

4,000 or so are ash, while another 1,000 grace our parks and yards.

The good news for homeowners who have beautiful, old ash trees: “There is no reason for a landscape ash tree to die from Emerald Ash Borer anymore,” says Deborah McCullough, a professor of entomology and forestry at Michigan State University. “You can treat a tree for a lot of years before you reach the cost of removing that tree.”
