Abstract

The effectiveness of riparian management practices, in particular along small streams, has not been adequately tested. In our replicated, before-after control-impact study of 13 small streams we are testing the effect of different levels of riparian reserves (controls, 30 m buffers, 10 m buffers, clearcuts) for protecting stream and riparian ecosystem components and processes. We also will add an additional partial harvesting along three new streams (compared to three original controls), for which we now have over a year of pre-treatment data and the cutting plans are made. In each case a suite of chemical, physical, and biological measures are used to compare the impacts of management and recovery. The stream and riparian system systems continue to be affected by harvesting even 3 years post-harvesting. We will study the continuing changes, the eventual recovery dynamics, and the effects of partial harvesting trials along these small streams and their riparian areas.
