Firewood RootballHarrisburg – Pennsylvania could be responsible for introducing emerald ash borer to Vermont through the shipping practices of some Pennsylvania nurseries.

 

Vermont recently found Emerald Ash Borer (EAB) in their state in late March.  During the investigation as to how it may have found its way there, Vermont officials discovered that some nurseries have adopted the practice of using firewood to brace the root balls of trees to prevent the tree from rolling during shipping.  

 

Firewood Rootball 2When you stop and think about it, a piece of firewood could be handy to use as a wheel block on tires, to place under a tractor bucket to minimize shifting during transport, etc.  After it reaches its final destination, you can take it camping or throw it in the fireplace.

 

One big problem with this multi-functional piece of wood: they carry pests.  Two pieces of black walnut 18 inches long and 4 inches wide with bark can have over 20,000 walnut twig beetles and fungus, a piece of ash may have a couple of EAB or maple may have a couple of Asian Longhorn Beetle (ALB). 

Please be on the lookout for practices such as this. You may not only be moving a pest, you may be breaking the law. The pictures from above are from a nursery in Bucks County.  They shipped to a nursery in Vermont, violating the Federal emerald ash borer quarantine and the Pennsylvania state walnut thousand cankers disease quarantine.
