Stream Monitors

Stream Monitors have the opportunity to contribute to an integral part of the GRNA Natural Resources Management Plan, as volunteer-led efforts to sustain and monitor the health of our streams is a key component of the management plan. Stream Monitors take part in two stream sampling events each year, one in the spring and one in the fall. Sampling involves working in a small team of volunteers to collect macroinvertebrates at a creek site and sorting through them for later identification by expert entomologists. Collected data is used to guide resource management decisions at GRNA.
