1. The Emerald Ash Borer and its Effects on the State of Michigan’s Ash Tree Population Environmental: Intro to Global Change Fall 2006 Jeremiah Jaroch Michael Rado Alessandra Martin

2. The Emerald Ash Borer (EAB) (Argrilus planipennis) Invasive species found in Southeastern Michigan in 2002 Kills ash trees (Fraxinus ssp.) at an alarming rate Already killed over 15 million trees in MI Image 1

3. Our Project: Importance Local issue Invasive species can alter ecosystem and biodiversity Must be dealt with quickly and efficiently

4. Our Project: Hypothesis EAB has adverse effects on biodiversity in MI ecosystem EAB has Potential to wipe out entire population of MI ash trees within 30-40 years Absence of ash trees has an effect on many other species Graphs of actual EAB impact on ash tree population Image 2

5. EAB Facts Natural Habitat: Eastern Russia, Northern China, Japan and Korea Brought to MI in ash wood products Discovered killing ash trees in MI in 2002 Can kill a mature ash tree in 2-4 years Bore holes in bark, lay eggs in phloem Larvae eat phloem, starving tree of nutrients Image 3

6. The Ash Tree Importance Bear fruit year-round Importance source of seed production Colonize disturbed areas in forests Keystone species Economically lucrative resource Image 4

8. Risk of EAB Infestation in the United States Image 6

9. Probability of EAB Infestations in Michigan Image 7

10. Quarantined Areas of Michigan Image 8

11. Images 9 and 10 Model of EAB Infestations 30 and 40 Years After of Initial Outbreak EAB Infestation Model Year 30

12. Decreased by 619,072 trees in one year (Forest Inventory and Analysis Data Center)

13. Decreased by 1,596,571 trees in one year (Forest Inventory and Analysis Data Center)

14. What Has Been Done Michigan Department of Agriculture EAB Task Force Established US Department of Agriculture Expensive endeavor

15. Conclusions EAB spread is at a rate high enough to eliminate ash tree population in Michigan Decline in ash tree populations is significant The absence of the ash tree will negatively effect biodiversity
