19 EAB Status in Upper Michigan

20 Detection Efforts in Upper Michigan 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

21 Tree Mortality - MI 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

22 EAB Status in Minnesota

23 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

24 Tree Mortality - MN 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

25 EAB Status in Wisconsin

26 Wisconsin 2014 New County Detections Adams, Buffalo, Calumet, Columbia, Door, Grant, Jefferson, Monroe, Oneida, Sheboygan

27 EAB Detections as of October 9, 2014

28 Wisconsin does maintain a website that lists eab finds within a county The table shows a partial list from that site as of October 20, ssets/confirmedeabfindsinwisconsin.pdf

29 Tree Mortality - WI 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

30 Mortality Polygons Late Summer 2014 Bill McNee, WI DNR

31 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 The following photos are from 2014, taken by B. McNee in the Newburg, WI area.

37 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
