Forest and fisheries managers are concerned about the incremental effects of land use on summertime temperature of some streams in BC, such as the Horsefly River and its tributaries. Reducing stream shade is well-established mechanism by which forest practices can increase stream temperature but we do not have a good understanding of how much shade there is on undisturbed streams, how much it is reduced by harvesting, and the rate at which it recovers after disturbance. Also, a stream can warm up in a clearcut and then cool when it flows back into a forest at a rate that is not well known. For these reasons, we do not have a good ability to manage shade and temperature over watershed scales. This project is documenting average shade and other properties of a sample of stream reaches having different widths and several stages of riparian vegetation. The results are suggesting that it will be feasible to develop a predictive model for stream shade for the geographic area sampled thus far.
