The State of Maryland reports that Prince George's County is the only Maryland county to be affected so far. The problem was discovered at a single nursery in 2003. Eradication efforts were attempted, but later tests revealed that they were not completely successful. I heard that every bill of sale at the nursery was reviewed to find the destinations of trees that were possibly infected, and eradication experts visited those destinations to destroy trees. A quarantine order was issued to prohibit anyone from moving ash trees, ash firewood and ash wood products.
Emerald Ash Borer traps can be seen throughout Bowie.
This notice is stapled to the tree.
