12th county in state now under quarantine
The emerald ash borer (EAB), an exotic species of beetle that kills ash trees, has been confirmed Cedar Creek Township in Allen County at a city wood lot. As a result, the DNR will issue a quarantine for most ash products and some other wood products in the county.
The quarantine will prohibit transportation of ash trees and most ash tree products out of Allen County. The ban will include ash nursery stock, ash logs or untreated ash lumber with the bark attached; any type of firewood except for pine; and any composted or uncomposted wood chips or bark chips that are one inch or larger.
Cedar Creek Township specifically will be regulated under this quarantine, which means that ash products will not be able to be moved out of the township or out of the county without permission from DNR. These measures are designed to slow the spread of the infestation while federal and university scientists continue to look for ways to better manage the pest in the United States.
?This destructive insect is very easily moved into other areas, especially when transporting firewood,? said DNR Director Kyle Hupfer. ?We need the public?s continued cooperation with not moving firewood into or out of affected areas, something with which we will really need hunters' cooperation this time of year.?
DNR personnel and others will periodically survey the area around the infestation. Residents of the area should be able to easily identify these workers, who will be wearing distinctive DNR clothing.
Other infestations in Indiana have been found in Lake, Porter, White, St. Joseph, LaGrange, Steuben, Randolph, Huntington, Hamilton, Marion and Adams counties. Large infestations are present in Michigan, Ohio and Canada.
Jodie Ellis, the exotic insects education coordinator at Purdue University, said pinpointing exactly where the EAB is in the state has been challenging because it often takes two to three years for ash trees to show symptoms of infestations.
Homeowners and others who come in contact with ash trees can help slow the spread of the EAB.
"We rely on local residents, foresters, loggers, tree removal or trimming crews, and others to report possibly infected sites," said Dr. Robert Waltz, state chemist and entomologist. "The public also can help us manage the spread of this insect by not moving firewood and by burning all campfire wood they have while at a campsite."
Residents who see evidence of the emerald ash borer should call Ellis, (888) EXT-INFO or (888) 398-4636; or the DNR Invasive Species Hotline, (866) NO-EXOTIC or (866) 663-9684.
The adult EAB is slender and a bright, metallic, coppery-green color. It is about one-third of an inch long, making it difficult to spot in tree leaves. The adult insect is visible only during the summer months. During the cooler months, the EAB is in its larval, or immature, form and can only be found under the bark of ash trees. Emerald ash borer larvae destroy live ash trees by eating the vascular tissue, which supplies nutrients to the tree, Ellis said.
It's difficult to distinguish EAB damage from that caused by the many native borer insects that attack ash trees. Two of the main ways to tell EAB damage from that caused by native species are by the EAB?s characteristic D-shaped exit holes in the main trunk of the affected tree and by the S-shaped feeding tunnels beneath its bark. Other symptoms include vertical splits in the bark and increased woodpecker activity.
