Tools for managing the impacts of forest practices on stream temperature

The Timber Harvesting and Silvicultural Practices Regulation recognizes that summertime stream temperature can be increased if stream shade is reduced. However, its requirement for temperature sensitive streams is not quantitative and therefore does not encourage rational management. The proposed study would contribute to the development of a quantitative approach to managing shade through the application of reach-scale stream temperature models. Forest harvesting reduces canopy cover and thus increases incident solar and daytime net radiation. This study will test different measures of canopy cover for estimating net radiation over streams through comparison with measurements of both solar and net radiation. Measurements will be made along streams with a range of riparian treatments and thus canopy cover conditions. Future components of the study will incorporate the net radiation model into a reach-scale stream temperature model designed for operational use within British Columbia.
