Approximately 42% of Canada is covered by forests, which in turn can be sub
divided into nine distinct forest ecozones. Many forested ecozones are loca
ted in northern Canada, where cold winters and cool summers provide forest
environments that are less well-understood that those in more temperate loc
ations. A number of major developments in recent years have stressed the ne
ed for enhanced understanding of hydrological processes in these forest lan
dscapes. These include an increased emphasis on sustainable forest manageme
nt in Canada as well as major scientific initiatives (e.g. BOREAS) examinin
g water, carbon and energy fluxes in forest ecosystems, with a particular f
ocus on boreal and subarctic forests. Recent progress in our understanding
of forest hydrology across Canada is reviewed. Studies of hydrological proc
esses across the spectrum of forest ecozones are highlighted, as well as wo
rk on hydrological responses to forest disturbance and recovery. Links betw
een studies of hydrological processes in Canada's forests and other fields
of research are examined, with particular attention paid to ongoing efforts
to model hydrological impacts and interactions with the climate, biogeoche
mistry, geomorphology and ecology of forested landscapes. Copyright (C) 200
