With warmer weather approaching, New Yorkers and people all across the Northeast are bracing for the coming of the Emerald Ash Borer or EAB. EAB is an invasive, exotic insect that quickly kills all ash trees once it becomes established in an area or community.  It was first discovered in the U.S. in 2002 in Detroit and has since been found in 18 states and two Canadian provinces. In February, the New York State Departments of Environmental Conservation and Agriculture & Markets expanded the state's quarantine on the transport of firewood, ask tree lumber, and other regulated articles to include 22 counties. You can take action to help stop the spread to NY’s estimated 900 million ash trees by following these steps.
