������Officials keep eye out for ash tree bug in N.D., Minn.
Homeowners and cities once relied on the sturdy ash as a replacement for trees felled by Dutch elm disease.
Now ash trees face an epidemic of their own.
Local foresters say the emerald ash borer – a devastating beetle so far found in five states to the east – could eventually spread to area ash trees. They just don’t know when.
“What we do know is when it gets here, the effects are going to be pretty overwhelming,” said Michael Kangas, a forest health specialist for the North Dakota Forest Service. He’s based at North Dakota State University.
West Fargo and Fargo have taken ash off the list of trees that may be planted on boulevards, city foresters for both jurisdictions said. Moorhead hasn’t officially taken the tree off its list, but it issues a disclaimer about the insect, city forester Rod Eggiman said.
Fargo’s Forestry Department is taking further steps, including implementing a program to replace ash trees that appear to be declining, City Forester Scott Liudahl said. The department is also working on a plan in case the pest does arrive.
“It kind of lays out the details of what we’ll be doing, who’s going to be in-volved, things like that,” he said.
An adult emerald ash borer can move about a mile or two by itself, said Rick Abrahamson, Clay County extension educator for the University of Minne-sota Extension.
But the insect can also spread when people move infected ash wood.
The emerald ash borer is troublesome for several reasons.
One is that it does not discriminate.
“Unlike native ash boring pests, this one seems to kill any ash tree regard-less of whether it’s healthy, weakened,” Kangas said.
While Dutch elm disease affects the American elm more than other kinds of elm tree, the emerald ash borer affects all kinds of ash, said Yvette Gherke,

West Fargo’s city forester.
The adult insects nibble on the tree foliage and do little damage. Larvae, however, feed on the trees’ inner bark and prevent the tree from transporting water and nutrients.
Emerald ash borers were discovered in Detroit in 2002, and so far have killed more than 25 million trees, Kangas said.
When officials find infestations, they generally create quarantines that pre-vent people from transporting infested trees to other areas.
But the problem is already there.
“By the time we realize we’ve got the emerald ash borer, we’re already way behind the ash borer, so to speak,” Abrahamson said. “That’s what hap-pened in Michigan. The insects had been there for several years before somebody found them.”
Minnesota conducts tests to see whether the ash borer has arrived, and so far traps haven’t shown evidence of the insect.
“But it is still possible that there may be some,” Abrahamson said.

It is that time of year again – introduction of the 2007 Minnesota Tree Care Advisor participants. Typically, I use the term rookies or newbies but I don’t exactly feel comfortable referring to this group of TCAs as rookies. Yes, technically they are rookies within the TCA program, but in the realm of the green sciences or industries we have a pretty solid crew of seasoned veterans in the mix.
Gary Wyatt, TCA and Regional Extension Educator, and Gordon Herbst, veteran TCA, are hosting a session in Saint Peter on the campus of Gustavus Adolphus within the confines of the Linnaeus Arboretum. Gary Johnson and Dave Hanson each have the opportunity to spend a day with the Saint Peter crew. Saint Peter Core Course participants…
Meanwhile, back in Saint Paul we are holding the 14th annual TCA core course. Saint Paul Core Course participants:
This course is being handled by Gary Johnson and Dave Hanson with special guests Dave Simmons: Nursery Inspector with Minnesota Depart-ment of Agriculture, Tessa Pinkstaff: Great River Greening, Barb Spears: Tree Trust and Don Mueller: Minnesota Department of Natural Resources.
As in the past, these new tree-huggers (MN TCAs) will be ready to help the urban forests of Minnesota …
Let’s welcome the newest TCAs and give them a hand!
