(Class A noxious weeds are those noxious weeds not native to the state that are of limited distribution or are unrecorded in the state and that pose a serious threat to the state). The Wetland and aquatic weed quarantine is established against nonnative, aggressive weeds that threaten Washington waters and wetlands: Washington waters and wetlands are threatened by nonnative, aggressive weeds that destroy the commercial, aesthetic, fish and/or wildlife habitat, and recreational value of these areas. These rooted or freely floating plant species, when established, form dense stands or mats that clog irrigation systems and waterways, displace native species, alter fish and wildlife habitat, and/or seriously impact recreational use of the waterways.
