Maryland teams protect trees by hunting ash borers - baltimoresun.com:
Armed with a map and a big box of traps, Mickey Kopansky and Charles Pickett are on the hunt for the Green Menace.

Emerald ash borers have already killed tens of millions of ash trees across the United States. The invasive species of beetle from Asia was introduced through wood packing material in 2002 in Michigan and through nursery trees a year later in Maryland.

If they're not stopped, the carnage will continue around the country and perhaps even in metropolitan Baltimore, where ash trees are the most common tree, frequently used for landscaping and fire wood, as well as tool handles, flooring and baseball bats.
