New Emerald Ash Borer Quarantines Cover Seven Southwest Wisconsin

Gilson, 608-224-5130 email@example.com Jim Dick, Communications Director,
MADISON ¡V Seven new southwestern
Wisconsin counties will be added to Wisconsin¡¦s emerald ash borer quarantine
list. EAB has been confirmed in three of the counties and is likely present in
the other four, state plant pest authorities said.
The Wisconsin Department of
Agriculture, Trade and Consumer Protection will quarantine Columbia, Grant and
Monroe counties after finding the destructive pest there. Richland, Iowa,
Lafayette and Green counties will also be quarantined, because they are now
surrounded by counties where EAB has been confirmed.
¡§Because of the proximity to EAB
populations in neighboring counties, and the historic patterns of movement of
goods that are regulated under quarantines, we are taking the precautionary
measure of quarantining these four counties,¡¨ said Brian Kuhn, director of the
departments¡¦ Bureau of Plant Industry. ¡§Low-level EAB infestations often go
undetected, so there is a high likelihood that EAB is already there. From the
way EAB has spread in the neighboring counties, we know that even if EAB is not
there already, it will be before long.¡¨
The ash-destroying insect was confirmed
in these locations:
Columbia County ¡V On the southern edge of Wildenburg Sand Prairie Park in the Town of
Lodi, along County Road V.
Grant County ¡V At Nelson Dewey State Park in the Town of Cassville, along
the road to an overlook and picnic area, and in Stonefield Historic Village.
Monroe County ¡V In the village of Oakdale at the interchange of Interstate
90/94 and County Road PP.
The quarantines will apply to the
entire counties. Quarantines prohibit ash wood products and hardwood firewood
from being moved out of the county to areas that are not quarantined. For
businesses handling wood products that could carry EAB, this means that they
must work with DATCP to assure that their products are pest-free before
shipping to non-quarantine counties. For private citizens, a quarantine means
that neither residents nor tourists may take firewood from these counties to
¡§Quarantining the extra four counties
where we have not yet confirmed EAB actually reduces the regulatory burden on
the forest products industry and citizens across the region, because it allows
movement of ash materials and firewood across contiguous counties within the
quarantine area,¡¨ Kuhn said. ¡§However, even though it is not illegal to move
firewood and ash products within the quarantined area, it is still a bad idea
and we would discourage it. You could be introducing EAB and other pests to new
areas in those counties that might otherwise remain uninfested for several
The quarantine will be put in place
temporarily by a Wisconsin emergency rule, until the U.S. Department of
Agriculture completes the process to enact a federal quarantine.
DATCP recommends that property owners
who have ash trees in quarantine counties:
Keep a close watch for possible signs of EAB infestation: Thinning canopy,
D-shaped holes in the bark, cracked bark, branches sprouting low on the trunk,
and woodpeckers pulling at bark. „h Consider preventive treatments if your
property is within 15 miles of a known infestation.
„h Consider planting different species
of trees that are not susceptible to EAB.
„h Call a professional arborist, and
visit emeraldashborer.wi.gov for detailed information.
Emerald ash borer is native to China
and probably entered the United States on packing material, showing up first in
Michigan about 10 years ago. It was first found in Wisconsin in 2008 in
Washington County. Other quarantined Wisconsin counties are Brown, Crawford,
Dane, Dodge, Door, Douglas, Fond du Lac, Jefferson, Kenosha, La Crosse,
Milwaukee, Ozaukee, Racine, Rock, Sauk, Sheboygan, Trempealeau, Vernon,
Walworth, Washington, Waukesha and Winnebago.
EAB adults lay eggs on the bark of ash
trees in mid- to late summer. When the eggs hatch a week or two later, the
larvae burrow under the bark for the winter and feed, forming the
characteristic S-shaped tunnels and destroying the tree's ability to take up
nutrients and water. In summer, the adults emerge through D-shaped holes in the
