Studies have been carried out on the use of the artificial substrate technique as a means of sampling the attached periphyton community in streams. The work involved the comparison of periphyton community composition and biomass accumulation on artificial substrates as it is affected by artificial substrate types, position, and exposure time. These results were then compared to the results obtained from the community on the natural rock in the stream. The data indicates that significant differences in species composition and relative abundance can be obtained on artificial substrates, and these differences may not always reflect the biodynamics of the periphyton community in the stream.
