"This is a significant find underscoring the importance of not moving hardwood
firewood in Michigan," said Mitch Irwin, director of the Michigan Department
of Agriculture (MDA). "Based upon extensive visual survey conducted this summer
in state, national and private campgrounds across the U.P., this appears to
be an isolated infestation, and we are responding quickly and aggressively to
eradicate it."
Survey crews from MDA, the Michigan Department of Natural Resources (DNR),
Michigan Technological University (MTU) and the U.S. Forest Service spent the
summer surveying high-risk areas in the U.P. for signs of EAB. High-risk areas
include all campgrounds (national, state and privately owned), boat launches
and lake associations with high tourist/camper traffic.
The infestation at Brimley State Park is the first place where EAB has been
found in the U.P. Detection trees established by MTU yielded two EAB larvae
in early September. A detection tree is a selected ash tree that has been "girdled"
– a process removing a ring of bark from the tree trunk – to stress
the tree. Research has shown EAB adults are more likely to lay eggs on stressed
trees.
Researchers and Response Project partners will implement the appropriate actions
for eradicating the infestation. "The eradication strategy for areas like Brimley
includes removal of all ash trees within a half-mile from any known site of
infestation," said DNR Director Rebecca Humphries. "We must protect our forests
from the immediate threat that EAB presents while managing these resources long-term."
"Despite the federal government's funding reduction this year, the Governor's
office is working aggressively with our Congressional delegation to make sure
we have adequate federal dollars for 2006," said Patricia Lockwood, EAB policy
director for Governor Jennifer M. Granholm. "Without a stronger federal commitment,
the risk of EAB spreading across North America is greatly increased."
Emerald Ash Borer is an exotic, aggressive beetle native to Asia and was discovered
in southeast Michigan in 2002. To date, the pest is responsible for the death
or damage of approximately 15 million ash trees in the 20 quarantined counties
and 27 outliers. Outliers are areas of pest populations found outside of the
20-county quarantine.
