Cumulative watershed effects (CWE) of forest practice change vegetation cover, forest age and landscape characteristics, in consequence, alter stream habitat structures and influence forest fluvial species richness and abundance of benthic communities. Studies of cumulative impacts of forestry practices on biodiversity are a vital area of research for ecosystem conservation and forest management. Determining the significance of CWE on forest biodiversity requires taking into account biological communities and ecosystem functions with the key factors influencing aquatic habitat quality that is what sustainable forest management wants to maintain or restore.
