Abstract

This paper presents reach scale large wood (LW) budgets of 12 upland streams in the Okanagan Basin of British Columbia. The study included 100 m long reaches at 3 wildfire sites and 3 undisturbed sites in the Interior Douglas-fir (IDF) biogeoclimatic zone, and 3 recent Mountain Pine Beetle (MPB) infestation sites and 3 undisturbed sites in the Montane Spruce (MS) zone. Detailed information on wood recruitment, output and storage were obtained from repeated annual surveys. An attempt is made to identify disturbance induced changes in a range of LW characteristics including absolute volumes of wood for each component of the budget as well as differences in wood stability and wood sources. MPB had not significantly increased LW recruitment, but is expected to increase over the coming decades. Storage rates at the disturbed streams indicated a net accumulation of wood over the study period
