EAA Takes Action to Protect Ash Trees
August 14, 2009 — EAA is taking pre-emptive action to ward off the destructive emerald ash borer, a major threat to ash trees all over the world. With nearly 1,400 ash trees on the EAA grounds, this is a serious threat, so insecticide treatments will be applied to prevent the pesky insect from thriving in trees at EAA.
The emerald ash borer comes from several countries in Asia, but has become widespread in the U.S. by ash wood used for packing and crating international trade goods. The bugs burrow into the trees to feed, depriving them of their nutrients. Large trees can die within 3-4 years of becoming infested. The public is being urged not to bring firewood from one location to another in an effort to mitigate the spread. As in past years, future AirVenture campers are urged to use only locally supplied firewood when on the grounds.
The insecticide will be injected into the base of each tree over the next few years. Without the injections, there is a risk of losing much of the shade on the EAA grounds. Nearby Fond du Lac and Sheboygan counties already have quarantines on moving firewood because of infestation, so protective measures are especially important for EAA’s ash trees.
