Ecological data collection at each site included the collection of biological communities and measurements of characteristics of riparian and instream habitat conditions. Three taxanomic groups -- fish, invertebrates, and algae -- were sampled because they respond differently to different environmental stresses. Physical habitat features are characterized both instream and along riparian areas. An example of some of these features include channel width, reach length, bank width, flood-plain width, water depth, water velocity, bed substrate, embeddedness, canopy angle, channel aspect, bank angle, bank height, bank shape, bank erosion, bank vegetation, and more. A complete list and definition of terms is detailed in the habitat protocols (Meador and others, 1993b).
