Dr. Robert C. Venette, a research biologist and director of the Minnesota Invasive Terrestrial Plants and Pests Center, is paying close attention to multiple invasive species, including "several bark beetles, emerald ash borer, spotted lanternfly, hemlock wooly adelgid, oak wilt, Palmer amaranth and Japanese knotweed, among others."

Residents might also notice a fungal disease on trees called oak wilt disease.

White oaks are also able to efficiently plug the water-conducting, tubelike cells called vessels in their wood with tyloses, balloonlike structures that seal the vessels as a barrier against deadly fungal diseases such as oak wilt.

They add that it is nearly impossible to detect diseases, like thousand cankers disease, which affects walnut trees or oak wilt in oak trees, just by looking at the wood.

The Department of Environmental Conservation says oak wilt was confirmed in the Yates County town of Middlesex after a homeowner contacted the agency to report several oak trees dropping leaves in July and rapidly dying.
