Spending time outside? Keep an eye out for Emerald Ash Borer
The State of New Hampshire is reminding residents and visitors of the steps they can take to help slow the spread of Emerald Ash Borer.
First identified in the state in 2013, EAB is now found in all New Hampshire counties except for Coos. A non-native beetle, EAB larvae feed on the inner bark of ash trees, which then die when they are unable to transport water and nutrients.
Currently, EAB is widely considered the most damaging forest pest in North America.
Trees infested by EAB can be visually identified in three ways:
- Through “blonding,” which happens when birds have removed an ash tree’s bark in search of EAB
- Through S-shaped patterns under bark
- Through D-shaped exit holes left by larvae.
The public can help slow the spread of EAB by limiting any movement of ash logs and firewood. In New Hampshire, ash firewood should not be transported more than five miles unless it has been seasoned for more than 12 months in the area where it was harvested, or it can be delivered and burned between Sept. 1 and June 1.
Anyone wishing to process ash logs should confirm that they are not infested or debark them immediately. Shipping ash logs out of New Hampshire to Maine still requires a federal compliance agreement.
The cost of EAB treatments, removals and replacements in the urban forest throughout all 25 infested eastern states is estimated to cost billions of dollars. The cost to forest landowners, the forest industry and the environment is virtually impossible to calculate.
Anyone who suspects that they may have found EAB should report their findings to nhbugs.org or call 800-444-8978.
More information related to EAB characteristics and outbreak locations, as well as steps that residents, visitors, municipalities and industries can take to help control the spread of EAB, can also be found at nhbugs.org.
