81st Forest Industry Lecture
Silviculture in Alberta: past, present and where to next.
Victor Lieffers has been a Professor of silviculture and forest ecology since 1983 and
is the past Chair of the Department of Renewable Resources at the University of
Alberta and past Chief Editor of the Canadian Journal of Forest Research. He has
published extensively in the areas of forest regeneration, ecophysiology, forest
ecology, mixedwood forestry and silvicultural practices and policies. Vic has
supervised >70 graduate students and postdoctoral fellows and is currently the Chair
of the Rocky Mountain Section of the Canadian Institute of Forestry.
In the past 70 years, Alberta silviculture has shifted away from a leave for natural regeneration after logging. In early years there was deep concern about a lack of regeneration of conifers after cutting. This concern promoted the research and development of improve nursery planting stock and procedures for handling and out-planting of seedlings, where today planting is the preferred means of regenerating conifers on most sites where they are desired. This shift towards planting, was coupled with increases in complexity of rules surrounding forest regeneration – linked to the performance of the regeneration and to the growth and yield of the stand and allowable cut of the forest. A more regulated forest is the result. I will make the argument that in future, silvicultural practices and outcomes for stands need to be more complex and variable. Forest resistance and resilience to disturbance may be the primary driver for what types of stands we produce. Resilience will be important to various aspects of biodiversity but it may also play an important role in maintaining forest growth and yield.
