A threat to Nebraska's ash trees has been found in northwest Missouri, less than 100 miles from Nebraska.
The Missouri Departments of Agriculture and Conservation and the U.S. Department of Agriculture say the emerald ash borer had been confirmed near Parkville, which sits on the northwest side of Kansas City, Mo.
Mark Harrell, of the Nebraska Forest Service, says there have been no confirmed sightings in Nebraska yet.
Ash trees account for 25 percent to 35 percent of trees in Nebraska. In Iowa, where sightings have been confirmed on the northeast side of the state, there are an estimated 88 million ash trees.
Larvae of the emerald ash borer beetle drill into ash trees, eat through vascular tissue and stop the flow of water.
