If invasives are allowed to spread, several ramifications can occur: good plant populations will eventually be crowded out and disappear; some noxious weeds are toxic to animals and to other plants (Knapweed is known to produce a toxin that is a natural herbicide, warding off good plants); erosion will set in and impact wildlife habitat and fisheries; your neighbors and/or county weed professional may put you in non-compliance; and your view shed will be greatly diminished.
