Aquatic invertebrates are excellent indicators of watershed health because they:
- 1. Live in the water for all or most of their life and often live for more than one year
- 2. Stay in areas suitable for their survival
- 3. Are easy to collect and identify
- 4. Differ in their tolerance to amount and types of pollution
- 5. Are important components of a stream′s nutrient and energy system
