Effects of logging on export of organic matter from headwater streams

This research will examine the effect of clear-cut logging of headwater, ESSF streams on the export of aquatic insects, detritus and dissolved organic carbon to lower, fish-bearing streams. During the one year of funding, 10 control and 20 clear-cut streams will be studied at the Taweel Lake and Penticton Creek sites. The large number of streams studied, and the use of two different ESSF sites will allow for application of the results of the study to a large area of the province. Pre-logging data will also be collected for a smaller number of creeks to allow for a full BACI design, should funding be extended over more than one year. The results of this study will be used to make management recommendations to forest managers regarding the effectiveness of riparian buffer zones. This will lead to greater certainty for managers using a results-based code, and to greater acceptance of BC forest products.
