Today the Bison went out in the field and collected data for a long-term statewide study of stream ecology. Students collected data regarding the amount of dissolved oxygen in the stream, turbidity, conductivity, temperature, pH, alkalinity, and the different types of macro-invertebrates. The data will be entered into a large data base that tracks stream health over the years and throughout the seasons. They also developed their own question for the stream which was: Is the temperature of a stream affected by stream bank vegetation? They concluded that data was insufficient because the streams were too different to accurately compare. It was a good day of data collection and gaining experience as a citizen scientists.
