Class Bs of Concern

The Class Bs featured here are either already found in Lewis County or have been confirmed in neighboring counties and are likely to be introduced. Weeds are often spread unintentionally through the movement of materials, such as hay, dirt, gravel, and woodchips. They are also brought in by pets, animals, floods, ATVs and other vehicles, and watercraft.
