Monitoring sites
Started: 1991-10-30Browns River and Stevensville Brook are monitored at 1400 foot elevation on each.
Sample collection
Duplicate samples of aquatic macroinvertebrates were collected using a standardized "kick-net" procedure. A sample consists of all the organisms and detritus dislodged from the substrate during two minutes of active substrate disturbance. Temperature, pH, alkalinity, and specific conductance of the water column are measured at the time the sample is collected. Organisms from the sample are separated from detritus and sorted into taxonomic groups.
Software: Paradox software
