Known as Alberta’s provincial tree, lodgepole pine is recognized by most Albertan residents by its tall straight narrow crown. On average 24 metres in height, lodgepole pine is typically found in dense, even-aged stands formed as a result of forest fires. The species primarily grows in pure stands and less often in mixed stands with other species. However, when in mixed stands, lodgepole pine is commonly found with white and black spruce, trembling aspen, balsam poplar, and Douglas-fir.
Lodgepole pine’s geographical distribution stretches to the east of the Rocky Mountains and foothill regions of Alberta. In Alberta, lodgepole pine extends from the southern U.S./Canada border up north to the 56° latitude. The species’ southern range is limited by precipitation within the prairie grassland regions, while its northern range is restricted by the aspen grove condition of the plains. Northeast of its range, lodgepole pine merges with jack pine where the two species hybridize. While smaller pockets of lodgepole pine stands can be found further north, these stands offer limited economic value.
The national inventory for lodgepole pine also includes jack pine and shore pine. Combined, the pine species account for just over 4 billion m3, or 20% of Canada’s total coniferous growing stock. In Alberta, pine accounts for nearly 616 million m3 or 41% of the provincial coniferous growing stock (26% of the province’s combined coniferous and deciduous growing stock). Exceeded by only the spruces, lodgepole pine contributes the highest volume to timber harvest in Alberta.
Pines in Canada can be classified into two groups; soft pines and hard pines. Both lodgepole pine and jack pine are hard pines. They have prominent latewood, therefore the wood is moderately hard and heavy.
