A new method of using artificial substrates for quantitative periphyton measurement was given preliminary testing over a 30 day period in Fleming Creek, Washtenaw County, Michigan. Results were encouraging, as this technique was found to be less time consuming than other methods. It also appears that this new procedure could be a valuable tool in addressing the problem of high variability between replicate periphyton samples. In this experiment variation of chlorophyllaconcentrations between glass slides was reduced to 4%.
