In Chicago and northeastern Illinois, ash trees are everywhere. And wherever there are ash trees, there's a good chance there are emerald ash borers (EAB). Despite their green color, these beetles are not good for the environment. They are, in fact, responsible for the destruction of the ash trees that comprise an estimated 20 percent of Chicago’s street trees. The EAB is native to Asia, but in June 2002, EABs were spotted in Michigan, their first appearance in the U.S. Six years later, an EAB infestation was confirmed at 29th and State Street in Chicago. Since then, the Illinois Department of Agriculture (IDA) has issued an eight-mile quarantine around areas with known EABs.
