This is an ongoing Citizen Science Experience. Contact the sponsoring organization to join in.
Emerald Ash Borer (EAB) was found in Concord in March 2013 and has steadily spread since. As a non-native insect, EAB lacks predators to keep it in check, and it has become a very damaging pest to NH's forests.
You can help protect New Hampshire's forests by becoming an EAB Detective! UNH Cooperative Extension and NH Division of Forests and Lands have been tracking the spread of EAB in NH, and have created a map of where EAB is known to be.
They need your help to effectively track this insect- Become an EAB Detective!
What you can do:
2. Look for blonding on ash trees. Woodpeckers are often the first to detect EAB, and scratch away at the outer bark to get at the larvae. This creates a "blonding" effect where patches of light-colored bark are exposed on the trunk of the tree.
3. Look for "galleries" or serpentine, s-shaped scars that weave back and forth across the grain of the tree - a tell tail sign of EAB.
4. If you see these signs on an ash tree near you - report it! Extension and the State of NH need your help to understand where the insect has spread.
