EAB Status in Upper Michigan
USDA Forest Service State and Private Forestry
Detection efforts by
the state of
Michigan have
dropped
substantially in the
western U.P.
No new county
detections in the
U.P. in 2014
Detection Efforts in Upper Michigan
USDA Forest Service State and Private Forestry
Widespread tree mortality
along Highway 2 between
Gladstone and Manistique
Significant tree mortality in the
Calumet area
Tree mortality in and around
Sault St. Marie and St. Ignace
Mapping ash tree mortality is
difficult in the eastern U.P. –
dead ash mixed with dead
American beech
Western U.P. has a much
more extensive ash
component

EAB Status in Minnesota
USDA Forest Service State and Private Forestry
Minnesota• 1 new county detection in 2014,
Olmsted County, City of
Rochester
• Twin Cities populations are still
confined to two counties
(Hennepin and Ramsey)
• Surveys in Duluth have been
conducted – still negative
USDA Forest Service State and Private Forestry
Winona County site has
widespread EAB activity and
dead and dying trees
Known infested trees are being
actively removed or treated in
the Twin Cities area, tree
mortality is not widespread in
the area

Wisconsin does
maintain a website
that lists eab finds
within a county
The table shows a
partial list from that
site as of October

Tree mortality is becoming
widespread and intense in
parts of southeast WI
Pockets of dead and declining
ash are also being reported in
SW Wisconsin
Dead and heavily declining
ash trees have been removed
in the city of Superior

Bill McNee, WI DNR
“Mortality in southeast Wisconsin is more
widespread in 2014 than last year and pockets of
heavy mortality have enlarged. Driving from Lake
Geneva to Kenosha to Milwaukee thinning trees
are seen continuously and there are pockets of
dead ash. Last year the area only had pockets of
thinning trees and a few dead ash. It is a very
noticeable change in a year. The area between
West Bend and Port Washington has changed in a
similar manner.” Bill McNee WI DNR

Summary Southeast and southwest WI have very active
EAB infestations, tree mortality is building
and expanding in these areas
EAB populations in the Twin Cities have not
yet exploded
EAB populations are just beginning to gain a
foothold in areas of the Western Great Lakes
that have extensive forest types dominated
by ash
