An observant landowner raised suspicions that emerald ash borer has infested ash trees in Victory, a Vernon County community, agriculture and natural resources officials said in announcing the new find.

The invasive pest kills ash trees, a predominant species on urban streets and in Wisconsin forests. State officials have requested a federal quarantine of Vernon and Crawford counties to try to contain the infestation. Residents are asked to take precautions, too.
