Document Summary

One factor that can influence stream temperature is logging activity. In small streams, trees often overhang the water, reducing light penetration to the water surface. If the vegetation is completely removed, there is a clear and immediate increase in stream temperature. Macdonald, of what is now called fisheries and oceans canada, and his colleagues at simon fraser. University, found that stream temperatures can be raised by 4 c 6 c, even five years after logging. The temperature changes can be in part mitigated by logging management practices, such as maintaining an unharvested buffer zone along the stream edge. However, macdonald shows that trees in these buffers are very susceptible to wind damage, reducing their effectiveness over time. Humans influence stream temperatures in a variety of other ways, including the construction of dams. Dams used to generate electrical power generally result in varied stream flows, depending upon the electrical needs at any point in time.
