Increasing concerns regarding the impacts of traditional forest management practices are leading to a diversification in silvicultural treatments. Consequently, the development of partial cuts has been a priority during the last two decades. Although important advances have been made, the effects of partial cuts in terms of tree growth, mortality, and aboveground carbon sequestration are not well understood. This thesis will study the influence of several partial cuts on the growth shock and the aboveground carbon sequestration rates. In addition, the possible relationship between root grafting and tree vulnerability during windthrow events will be evaluated. Jack pine-dominated esker forests of the Abitibi-Témiscamingue region (Quebec, Canada) located on two types of sandy soils have been chosen for this study. An experimental design including control and managed stands with two harvest intensities (25-35 and 40-50 %) have been selected for the first two chapters. Four replicates per treatment and four replicates per control stand type will be sampled in rectangular experimental plots that will be installed in each replicate for the first two chapters. Four windthrow-affected riparian buffers have been selected for the first chapter. The growth response over time will be estimated by a dendrological approach based on the extraction of increment cores in 36 trees per plot (864 cores). Isotopic δ13C will be calculated from each increment core in order to evaluate if growth shock is produced by tree stress and if it is related to harvest intensity or the distance to the skidding trails. Moreover, allometric equations will be used to calculate stand aboveground carbon sequestration rates. In addition, a high-pressure water spray will be used in each riparian buffer to excavate, expose, and analyze root grafts. The results of this research will be essential to gather further knowledge of the impacts of partial harvesting that will allow us to provide silviculture with more accurate prescriptions for the implementation of partial cuts in the Canadian boreal forests. Moreover, this thesis will be pioneer in the study of the growth shock genesis, the effects of partial cuts in esker ecosystems, and the complex relationship between root grafting and tree mortality.
