Our last stream monitoring event showed that herbicide applications do effect our macro invertebrates. The park had been sprayed for some invasive plant management about a week before our event. Unfortunately the week of rain probably washed some of the herbicide into the stream resulting in our low numbers of macro invertebrates. The stream received a score of 2 out of 10, which translates to unacceptable ecological conditions. We saw mostly worms and midges which are tolerant of impairment and our net spinner population was low. |
