Noxious Weeds

What Are Noxious Weeds?

Noxious Weeds are unwanted plants that cause harm to:

Agriculture   People   Recreational Areas

  • Noxious weeds are harmful because they are invasive.
  • Invasive weeds are not native to our area and have no natural enemies to control reproduction. These invasive species can crowd out desirable vegetation.
  • The management of noxious weeds is necessary to conserve and improve natural resources such as cropland, soil, forage, and wildlife habitat and to manage land resources for multiple use values and improve the economic stability within Eureka County.
  • Keep in mind that weeds on the Nevada Noxious Weed List have to be our first priority. While plants like halogeton and purple mustard can be considered toxic they aren't considered invasive and we aren't treating them at this time.
