In late April 2016, four emerald ash beetle adults were located in a trap by the Texas A&M Forest Service in Harrison County (near the Louisiana & Arkansas borders). Currently, there are no confirmed trees infested with emerald ask borer.
Emerald ash borer, often shortened to EAB, are invasive beetles that attack stressed and healthy ash trees. These beetles are native to Asia and were discovered for the first time in the U.S. in Michigan back in 2002. The beetle has now spread to 26 states and killed millions of ash trees. The beetles are aggressive and can kill an infested ash tree within 2-3 years.
According to the Texas A&M Forest Service, there are 16 species of ash in the U.S. and 7 of those can be found in Texas.
A statewide plan involves monitoring of beetle movement; educational programming; providing technical assistance in prevention, preparation and recovery; and working with regulatory agencies in regards to quarantines. The Texas A&M Forest Service is also working to slow the movement of the beetle.
“Proper planning can reduce the impact of EAB in our communities,” said Texas A&M Forest Service Urban and Community Forestry Program Coordinator Paul Johnson. “Removal of poor quality ash, planting trees that aren’t susceptible to EAB, and protecting high value ash by treating them will help us weather this attack. Work with a forester or an ISA-certified arborist to help you assess your EAB risk and care for your trees.”
