The Ash Tree Project

2014/06/11

The Ash Tree Project (ATP) aims to treat select high-value ash trees (fraxinus spp.) with the trunk-injected insecticide emmamectin benzoate (trade name “TREE-age”) to prevent near-certain mortality due to the exotic invasive pest Emerald Ash Borer (EAB – Agrilus planipennis).  Treatment with TREE-age is commonly considered being effective for a two-year period, with some municipalities using a longer interval.

ATP is a conservation project of the local Audubon chapter – Audubon Miami Valley (AMV).  Initially funded through an Audubon Collaborative Funding Grant, ATP was given a huge boost in May 2014 by a donation from the Arborjet company of application equipment, one liter of insecticide, and a half-day of on-site training from Arborjet representatives on 5/29/2014.

The priority treatment area is a 200+ acre tract known as Hueston Woods State Nature Preserve (HWSNP), aka “Big Woods”, within Hueston Woods State Park. HWSNP is a stand of “old growth” timber, a beech-maple forest designated in 1967 as a National Natural Landmark. (read more)
