Identifier les arbres les plus susceptibles de mourir après une coupe partielle dans l'érablière ou la bétulaie jaune

Abstract

Many research findings related to tree mortality have been published since 2005, and it is now possible to assess postselection cut tree mortality risks in maple or softwood/yellow birch forest stands. This paper sets out some simple, practical criteria that can be used to identify the trees most likely to die, for inventory and tree marking purposes prior to partial cutting. Crown dieback and low quality of the butt log are the two main indications that a sugar maple (Acer saccharum Marshall) is at high risk of mortality. As for yellow birch (Betula alleghaniensis Britton), the presence of a major defect in the trunk or crown dieback are the two main indications of a high risk of mortality. The mortality risk of the other companion species of these stands generally increases with their diameter.
