Additionally, if abundant, healthy and diverse periphyton and macrophytes are observed in a stream (see Figure 5) it is unlikely that herbicides are responsible for the impairment. However, herbicide-resistant and other non-target plants may increase in abundance with herbicide exposure, due to reduced competitive pressure from affected plants. DIN OT Figure 1.
