Abstract

Two experimental clearcuts were made along Bratton Branch in Louisiana. Four sites were established for sampling water quality, habitat characteristics, benthic and drifting macroinvertebrates, and fishes. Changes in dissolved solutes, acidity, dissolved oxygen, suspended solids and turbidites, nutrients, and sediment analyses were also analyzed. Initial results emphasize the importance of the streamside management zone (SMZ) in maintaining allochthonous coarse particulate organic matter (CPOM) inputs to streams from riparian deciduous trees. Overall, clearcutting effects on Bratton Branch macroinvertebrates were minimal. Analyses of 18 fish species revealed no significant differences in species diversity at any site before and after timber harvest.
