Dataset Overview
Macroinvertebrate Community Assessments are based primarily on eight metrics of the Macroinvertebrate community. These include metrics of abundance, species richness, and indexes of Sensitive to tolerant species ratios. Data come from Ranch Brook at a location about 50 m below the first bridge crossing in Mansfield state park (44.50361, -72.78194) and were extracted from https://anrweb.vt.gov/DEC/IWIS/.
- Purpose
The effectiveness of a forest in providing clean water is assessed through the diversity of key indicator species of stream health. A stream indicator species in this context is a macroinvertebrate (insects, worms, or snails) whose presence, absence, or abundance reflects the current condition of the environment. Macroinvertebrates typically require high levels of dissolved oxygen and low turbidity in the water.
