Students in AP Environmental Science recently completed an assessment of the quality of Reeves Creek (near Thacher) by sampling for the macroinvertebrates that inhabit the substrate. Based upon the relative dominance of the species, students were then able to calculate a water quality index. The field work involves using the kick-seine technique (a lot like […]
