The following statistical information has been extracted from the Canadian report to the 24th Session of the International Poplar Commission, held in Dehradun, India in 2012, with some more recent updates.  That report covers the period 2008 to 2011.  For more information and background material on the challenges associated with obtaining specific information on poplars and willows in Canada, readers are directed to the full report, which is available on this site: Poplar and Willow Cultivation and Utilization in Canada. 2008-2011 Canadian Country Progress Report.

Canada is a forest country.

Canada has 10 percent of the world’s forests that cover 397.3 million hectares (ha) of forest, other wooded land and other land with tree cover, which represents 53.8 percent of its total surface area. Canada’s forest, other wooded land and other land with tree cover are made up of 347.7 million ha (87.5 percent) of forest, 41.8 million ha (10.5 percent) of other wooded land and 7.8 million ha (2 percent) of other land with tree cover. The predominant tree species on forest land are spruce (53.2 percent), poplar (11.6 percent) and pine (9.3 percent). The vast majority of the Populus inventory in Canada consists of natural stands.

Areas of natural poplar and willow

Areas (in hectares) of natural poplars and willows by species and ecozone based on the 2006 National Forest Inventory.  Inventory area estimates are derived from forest stands with dominant species either poplars or willows.  P = Populus (poplar); S = Salix (willow).

Hybrid poplar in Quebec

In the province of Québec, approximately 12,000 ha of fast-growing poplar plantations are industrially managed, while small private landowners have planted only 1000 ha. Most of these poplar plantations are established on clearcut forest sites (approx. 11,000 ha). […] Yields as high as 39.6 m3 ha-1 year-1 were observed after 6 years in a riparian agroforestry system (2222 stems ha-1) along a stream alongside a fertilised pasture in southern Québec. Very high yields were also observed in the St. Lawrence Valley, on abandoned farmlands (22.4 m3 ha-1 year-1 after 8 years, Montérégie region; 16.6 m3 ha-1 year-1 after 6 years, Lanaudière region) at intermediate stem density (833 stems ha-1). Available data from four clearcut site hybrid poplar plantations show yields varying from 0.5 to 1.4 m3 ha-1 year-1. These yields are lower than the mean yield of natural trembling aspen regeneration (3.4 m3 ha-1 year-1).  See also Fortier, J. et al. 2012.
