Résumé

In Canada, Norway spruce (Picea abies [L.] Karst.) is an exotic species mainly used as a fast-growing tree in intensive silviculture. However, this species is sensitivto attacks by white pine weevil (Pissodes strobi Peck [Coleoptera: Curculionidae]) (WPW), a pest that girdles and kills leader shoots, targeting open-growing individualwith fully sunlit terminals. We hypothesized that there is a compromise when releasing planted Norway spruce between growth interference by competing vegetatioand avoiding creation of favorable conditions for attacks and growth reduction by WPW. We evaluated the effects of stock type, scarification, and vegetation managemenon WPW incidence and early Norway spruce growth in southeastern Québec (Canada). Our study confirmed that after 11 growing seasons, the growth of Norway sprucseedlings was driven by the presence of competing species, a factor that can be managed through vegetation control. Although released seedlings were at a higher risof WPW attack, the trees were ultimately taller than those growing in control conditions. Although significant in some treatment combinations, stock type effects werlimited and marginal compared with vegetation effects. Scarification did not improve seedling establishment on this site characterized by a thin humus layer. © 2015 Society of American Foresters.
