Abstract

An increased demand on Canadian forest resources has necessitated a re-evaluation of available raw materials other than the traditionally prized conifers. The other species include deciduous trees (hardwoods) among which various species of Populus (poplars) occupy a significant position. Poplars constitute nearly 54% of Canada's net merchantable hardwood timber and 9% of the entire Canadian net merchantable timber resources (see Chap. XIV) . To meet increased timber requirements, the potential of poplars was realized much earlier in Europe than the U.S.A., and only recently in Canada. Features particularly favoring poplars include their great ecological amplitude, ease of propagation, fast growth and the multifarious uses of their wood. Judicious management of extensive areas inhabited by some of the native poplars and development of new hybrids would contribute significantly towards Canada's future forestry resources . All Populus spp. native to Canada extend to the U.S.A. where numerous workers are investigating their biology; these studies have contributed considerably to our knowledge of Populus spp. on this continent. This report reviews the available information on the silvical characteristics and ecological behavior of Populus spp. under Canadian condition .
