Greg Krogstad is an arborist with Rainbow Treecare. He showed us how healthy the ash trees are at the State Fairgrounds.

Krogstad's company is working with management at the state fairgrounds to protect their trees from emerald ash borer.

Throughout the 360-acre facility ash trees are all over the place. In fact, there are 684 of them living, breathing and providing shade during the Great Minnesota Get-Together. So far, the ash trees here have gone unharmed.

"They are really leaders in managing the trees here. So they have preventively worked to manage emerald ash borer," Krogstad said.

There's no doubt this beetle is in this area. The first case was found in the St. Anthony Village area right next to the grounds. They have since spread to surrounding communities. A new case of emerald ash borer was just found no more than three miles away in the 2800 block of Snelling Avenue. Krogstad says this new case is just the beginning of new infestations.

"We've begun to see that in January, new finding in Minneapolis, new finding in St. Paul," Krogstad said.

Krogstad says if you live in the 15-mile radius of a find, you need to get a plan and be concerned for your tree. He guarantees the ash trees at the fairgrounds will be here for the long haul if he has anything to do with it.
