资源简介：
Vermont DEC collects macroinvertebrate community samples during an annual index period that runs from September 1st through mid-October. Samples are collected from riffle habitats, and sorted and identified in the laboratory. DEC biologists use population data, as well as a number of community variables (called metrics) to assess stream health.
