The Emerald Ash Borer
(EAB)threat to our Ash trees remains very real. This past summer I was able to work with the Minnesota Department of Agriculture to assist with ongoing research and tracking of the EAB. I placed 7 purple EAB “traps” around the City. These traps are constructed of cardboard with a sticky surface to trap insects that come to it. While many insects are trapped, the trap contains special “scent wafers” that are particularly attractive to the EAB. At the conclusion of the study period, the traps were collected and the insects, including any EABs, documented. (In future issues of City Links, we’ll publish the findings.)Meanwhile, please contact me if you suspect a tree may be infected. We can take steps to slow the spread of the
infestation.

What can you do to help?
There are three simple things:
•Don’t transport firewood. Buy it where you burn it, and burn all of it where you buy it.
•Don’t buy firewood from outside Minnesota. Anytime you buy firewood, ask about the source of the wood. If it came from outside Minnesota, don’t buy it.
•Keep an eye on your ash trees. If you notice problems with your ash trees, call your city forester or county extension educator for help figuring out the problem. If you have to buy wood, buy MDA certified wood. MDA certifies wood
treatment based on standards set by the United States Department of Agriculture, allowing wood to be moved around the state. More information at www.SaveOurAsh.net
Emerald Ash Borer is in Minnesota
On May 14, 2009, emerald ash borer (EAB) was confirmed as present in the South Saint Anthony Park neighborhood in St. Paul. EAB is a serious invasive tree pest, and consequently a quarantine has been placed on Ramsey, Hennepin, Houston, and Winona Counties to help slow the spread of EAB to other areas.

What is EAB?
EAB is an insect that attacks and kills ash trees. The adults are small, iridescent green beetles that live outside of trees during the summer months. The larvae are grub or worm-like and live underneath the bark of ash trees. Trees are
killed by the tunneling of the larvae under the tree's bark.
Where is EAB?
EAB is native to eastern Asia but was discovered in Detroit, Michigan, and Windsor, Ontario, in 2002. Indications are it may have been introduced to this area as early 1990. EAB has been spread in ash firewood, nursery stock and possibly other ash materials to a number of new areas. View a larger interactive map of positive EAB finds
Why should I care about EAB?
EAB kills ash trees. All ash trees are susceptible to EAB and millions of ash trees have been killed in infested areas already. Minnesota has the highest volume of ash trees in the U.S. with almost a billion forestland and urban wood ash trees. The potential economic and environmental impacts of losing these trees is substantial. The cost of removing and replacing a single tree can range from hundreds to thousands of dollars – how many ash trees are in your yard?
What can I do about EAB?
> Don't import materials to Minnesota that could harbor EAB such as ash firewood (unless it's MDA Certified)
> Become knowledgeable about recognizing EAB and remain vigilant to the condition of your ash trees. The Minnesota EAB Science Advisory Group has prepared a document (PDF: 51 KB / 6 pages) describing the pros and cons of planting ash trees, pre-emptive removal and insecticide use.
What should I do if my ash tree is in decline
> Review diagnostic aids for identifying EAB symptoms
> Look into resources on maintaining tree health and/or
> Consult a local tree expert or local extension person
What can I do to keep my trees healthy
> Plant a variety of trees
>Use proper planting techniques
> Review resources on maintaining tree health and/or
> Consult a local tree expert or local extension person
