Advances in Canadian Forest Hydrology, 2003-2007

Recent research in forest hydrology in Canada is reviewed, with a focus on studies of hydrological and hydrochemical processes in natural and disturbed forest landscapes during the 2003-2007 period. The value of hydrologic classification schemes for understanding these processes and guiding effective forest management practices is highlighted, as are the spatially and temporally extensive hydrologic datasets needed to test these classifications. Studies of hydrologic response to natural and anthropogenic forest disturbance are reviewed, and the strengths and limitations of paired-basin experiments for assessing forest disturbance effects on watershed processes are evaluated. Recent shifts in the context of forest hydrology research in Canada are presented, such as issues of climate warming, the mismatch between experimental and management scales, and the increasing need to address cumulative effects of both natural and anthropogenic forest disturbance.
