Weed Laws

In recognition of the economic and ecological threats caused by invasive, non-native plants, Washington State has enacted laws to control the introduction and spread of these noxious weeds. The original goal of RCW 17.10 was to limit Washington's economic loss due to noxious weeds in and around agricultural areas. In 1987, this law was revised to incorporate noxious weed control in all natural areas, since the ecological impacts of noxious weeds are so closely tied with Washington's economy.
