Some description

Maybe you’ve heard of it. Emerald Ash Borer is wreaking havoc on ash trees around a large chunk of the country, including Minnesota.

The emerald ash borer (EAB) is an exotic beetle from Asia that was first discovered in the U.S. near Detroit in the summer of 2002.

While the adult beetles that nibble on ash foliage cause very little damage, it’s the larvae that feeds on the inner bark of ash trees that disrupt the trees ability to transport water and nutrients.

Although it can take years to build EAB populaSome descriptiontions large enough to infest entire trees, once an ash tree is infested it has almost no chance of survival.

The EAB spreads quickly and sadly, there is evidence of it in the Twin Cities metropolitan area.

What’s more, there are plenty of ash trees all over the Cities. In fact, there are close to one billion ash trees in Minnesota! Many of the trees infested with Dutch Elm Disease in the Cities in the 1970s and 80s were replaced with ash trees. Now, it’s a different infestation in a different type of tree, but similar situation.

So what are cities doing about it?

Emerald Ash Borer has not yet hit Columbia Heights, although the city started thinking about their EAB management plan in 2011.

We spoke with Kevin Hansen, Columbia Heights Director of Public Works and Gail Nozal, Area District Manager of S&S Tree and Landscaping Specialists, who outlined what they are doing.
