Ash Sentinel Tree Project

This is the pilot year for a citizen science project in which landowners who
already cut firewood can girdle an ash tree in the spring and then cut it down
and peel back the bark in the spring to look for emerald ash borer larvae. The
way this works is that ash trees that are stressed (a girdled tree is very
stressed) emit a chemical signal that is especially attractive to the little
green adult beetles looking for a place to lay their eggs. The girdled sentinel
tree should draw many of them in before they go to another tree in the surrounding
area, allowing the landowner to have an early detection tool literally in their
own backyard. For more information click here
