(2) Which variables best explain tree mortality by different modes of death (standing death, uprooting or stem breakage)? Decennial tree deaths were lower after partial cutting than in unharvested plots, but the annual proportion of tree death was similar (1.25%\u00b7year-1). At the tree level, a risk-product classification demonstrated the strongest evidence on influencing total mortality, followed by species, the presence of a logging injury, and tree size. Annual temperature was the only climatic variable explaining variations in total risk of tree mortality, and always among the first three variables explaining differences among the three modes of death. The risk of standing death also increased with increasing annual precipitation, while the risk of stem breakage and, to a lesser extent, of being uprooted, decreased with increasing precipitation. Additionally, we found strong evidence to support the effect of the potassium\/magnesium ratio of the humus layer on the risk of being uprooted. This information is critical to better understand tree mortality processes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Published in The Forestry Chronicle&nbsp;93(03): 246-258 We used a permanent sample plot network established to monitor the effects of forest management practiced in mature northern hardwood and mixedwood stands in Qu\u00e9bec, Canada to address two important questions related to tree mortality: (1) How does partial cutting affect tree mortality?
