Ten-Year Response of Sugar Maple–Yellow Birch–Beech Stands to Selection Cutting in Québec
Abstract:Experimental blocks were established in five regions of southern Québec to determine the response of hardwood stands to selection cutting. The blocks contain five control stands (no cut) and five treated stands, composed mainly of sugar maple in association with yellow birch and American beech. Treated stands were harvested using single tree selection to a residual density varying from 16.8 to 21.2 m2. Results obtained 10 yr after treatment demonstrate that the annual gross growth rate was not significantly different between treated and control stands. However, net annual growth rate was higher in four out of five cut stands, because the annual mortality rate was less in these stands than in controls. Cutting significantly enhanced the growth of stems with an initial diameter at breast height (dbh) of 10 to 28 cm and favored the development of sugar maple saplings in all blocks and yellow birch saplings in three blocks.
