Sapling based recruitment model for sugar maple-dominated stands of Quebec.


  • Hugues Power Ministry of Natural Ressources and Forests of Quebec.


Over the last few decades, compositional changes have been observed in the sugar maple-dominated (Acer saccharum) stands of southern Quebec. American beech (Fagus grandifolia) increases its presence and abundance to the detriment of the sugar maple. Recent works have shown that the ability of the growth models currently used for forest management to predict these transitions are limited. To improve the performance of the models, a new recruitment module was developed based on the sapling cohort characteristics. The module considers the number and size of saplings from the main tree species to predict the recruitment of new merchantable size trees. The new recruitment module improves the prevision accuracy of merchantable stem recruitment, and consequently, improves the prediction of future composition for sugar ample stands.

Hugues Power graduated from the forest management program of Laval University in 1998. From the same university, he obtained a master’s degree in forest science in 2009 and, later a Ph. D. in biology from Université du Québec à Montréal in 2013. Since 2012, he his employed as a researcher for the Ministry of Natural Ressources and Forests of Quebec. His research interests focus on growth and yield modelling of temperate hardwood and mixedwood stands.
