11 EAB Overview Origin: China Introduced: 1990 s First identified: 2002 (Chicago area 2006) Symptoms: tree thinning/dieback, woodpeckers Biology Larvae sever vascular system, cut off nutrient flow One generation (Egg to adult) per year Tree often infested 2-3 years before shows symptoms Symptomatic trees surrounded by infested but asymptomatic trees 11

12 Products That Work, From People Who Care

14 Why is EAB Such a Big Deal?

15 Why is EAB a Big Deal? Ash = dominant tree in urban landscapes EAB almost 100% lethal to ash EAB spreading rapidly EAB will be very, very costly 15

16 Ash Very Common Street Tree Ash Trees Lake Forest, IL Joe Chamberlin, Valent USA Corp 16

21 EAB Spreading Quickly Simulation of Emerald Ash Borer Spread Kovacs et al

22 Economic Impact of EAB 38 million ash in U.S. urban landscapes EAB will kill almost all in next 10 years (unless treated) Projected cost = $10-20 billion Worst invasive forest insect pest ever 22

23 Status of EAB in Naperville

24 Naperville Joe Chamberlin, Valent USA Corp 24

25 EAB in Naperville Number of ash trees Parkway trees: 15,200+ (27% of total trees) Residential trees: 2-3X parkway trees? 2008: EAB first detected in Naperville Spreading quickly Reported from 20 subdivisions Naperville EAB website aspx 25

29 Do You Own Ash Trees?

30 Ash Tree Identification 30

31 Ash Identification Compound leaves 5-11 leaflets per leaf Opposite branching 31

32 What Should You Do About EAB?

33 History: Response to EAB USDA-APHIS attempted to eradicate Removed all ash trees in infested area Feds paid for removal No treatment e initially Eradication effort quickly abandoned Current Approach Integration of treatment + removal 33

34 Tree Removal N O A 34

35 Chainsaw Did Not Stop EAB We need more tools in the tool box than a chain saw. - Dick Bean, EAB Eradication Program Director 35 Dick Bean, Maryland Dept. of Agric.

36 EAB Management Myths Tree removal slows the spread - False Treatment does not work - False Treatment too expensive - False Treatment t not safe - False 36

37 EAB Management Statement 37

38 EAB Management Statement Cost-effective, environmentally sound EAB treatment protocols are now available that can preserve ash trees through peak EAB outbreaks with healthy canopy intact. Used in association with tree inventories and strategic removal / replacement of unhealthy ash, tree conservation will help retain maximum integrity and value of urban forests. e e.i se ve_as ash.pdf 38

39 EAB Management Statement Support Continental Dialogue on Non-Native Forest Insects and Diseases Support Letter 22 signatories Nature Conservancy Society of State Foresters National Association of State Foresters Grantham Foundation for Protection of the Environment 39

40 Response Options Let EAB kill tree then remove Worst response Remove tree before EAB kills it Remove ash and replace with other tree sp. Conserve ash tree by treating with a registered product 40

41 How to Decide?

42 Tree Benefits Urban forest has huge value Economic Environmental EAB is not just a Tree Hugger issue 42

43 Risks Associated with Tree Loss Economic Tree removal and replacement 15 dbh ash: ~$1,500 (removal, stump grinding, replacement) Property value Property damage Environmental Ecosystem benefits Public safety Dead trees fall down! Tree removal 43

44 Trunk Diameter and Tree Value $ $ nual Va alue An $ $ $50.00 $ Trunk Diameter (inches) 44

65 EAB Treatment Calendar Ideal Treatment Time EAB Larvae Feed in Phloem Ash Flowers EAB Adults Feed on Foliage Apr. 1 May 1 Jun. 1 Jul. 1 Aug. 1 Sep. 1 Oct. 1 65

66 Will they impact ground and surface water? Will they impact aquatic organisms? What about residues in leaves that fall in autumn? Will they harm honey bees? Other insects? Woodpeckers? Will injection wounds harm the tree? Will EAB evolve insecticide resistance?
