Introduction
I am a PhD student at the University of Quebec in Abitibi-Temiscamingue. I studied in environmental protection, as technician, a bachelor in Biology and a Master degree. I have been working in research since 2014 as field and lab assistant for different projects on Forest Ecology, Climate Change, Silviculture and Natural Disturbances.
My current research evaluate the impact of spruce budworm outbreak on pine forest dynamics.

La tordeuse des bourgeons de l’épinette (Choristoneura fumiferana) (TBE) affecte une grande superficie du territoire québécois. En 2018, pas moins de 8 millions d’hectares ont été frappés par l’insecte. Plusieurs recherches ont démontré le rôle de la TBE dans la dynamique de la forêt boréale. Les conséquences de la TBE sur les arbres matures sont b...
Spruce budworm (Choristoneura fumiferana) is the main defoliator of conifer trees in North 13 American boreal forests, affecting extensive areas and causing marked losses of timber supplies. In 2017, 14 spruce budworm affected more than 7 million ha of eastern Canadian forest. Defoliation was 15 particularly severe for black spruce [Picea mariana (...

Avec le titre de la plus grande défoliatrice de la forêt boréale, la tordeuse des bourgeons de l’épinette joue un rôle majeur dans la dynamique des peuplements. C’est pourquoi les conséquences de l’insecte sur les arbres matures sont bien documentées, contrairement à celles sur la régénération. On prend conscience qu’il devient crucial d’en apprend...
Spruce budworm (Choristoneura fumiferana (Clem)) is the main defoliator in the boreal forest of North America, and its outbreaks have major ecological and economic consequences and represent a challenge for forest management. Numerous studies have addressed the effects of this defoliator on mature trees, whereas the effects of spruce budworm on reg...
Avec le titre de la plus grande défoliatrice de la forêt boréale d'Amérique du Nord, la tordeuse des bourgeons de l'épinette (TBE) fait couler beaucoup d'encre en raison des nombreux effets sur la productivité forestière. En 2021, la région de l'Abitibi-Témiscamingue est la deuxième région la plus affectée par la TBE avec plus de deux millions d'he...
Avec le déclin des peuplements de pin rouge (Pinus resinosa Ait.) et de pin blanc (Pinus strobus L.), il devient crucial de développer des pratiques forestières durables qui visent à rétablir leur dynamique naturelle en émulant les effets des perturbations naturelles. Dans cette optique, l'aménagement forestier écosystémique a été mis en place. Mal...

As the main defoliator in North American boreal forest, spruce budworm has major ecological and economic implications in forest management. For this reason, many researches studied the effects of this insect on mature stands were performed, while seedling defoliation continue being an understudied subject. Therefore, a large area of Canadian boreal...
Nos forêts sont soumises à des perturbations multiples, c'est pourquoi un projet a vu le jour afin de mesurer l'interaction entre les perturbations naturelles et les perturbations anthropiques, et ainsi mieux saisir l'influence que cette combinaison aura sur les forêts de l'avenir. Les coupes forestières et les épidémies d'insectes font partie des...
Les perturbations anthropiques (coupes forestières) et naturelles (épidémies d’insectes, chablis, feux, etc.) jouent un rôle crucial dans la dynamique, la structure et la composition des écosystèmes forestiers. Elles doivent être considérées de manière interactive et complémentaire lors de l’aménagement du territoire.

In 2017, more than 7 Mha was affected by spruce budworm [Choristoneura fuminera (Clem.)] (SBW) in Quebec (Canada). Many research evaluated the impacts and effects of SBW on mature stands, neglecting the impact on seedlings. However, during the last decades, intensive forest exploitation practises in Canadian boreal forests has provided a large surface composed by trees at young development stage. Seedlings are a major topic in Forest Ecology because it represents the future forests. Thus, it is essential to understand the impacts of the current SBW in the forest regeneration.
The main goal of this study is to evaluates the impacts of SBW on the defoliation of black spruce [Picea mariana (Mill.) B.S.P.] seedlings after clearcutting and partial cuttings using drone measurements in Canadian boreal forests. This project will provide a better understanding of natural disturbances impacts on regeneration as well as new tools to quantify the seedlings defoliation. Our results will be useful in the silvicultural evaluation of partial cutting in the context of forest sustainable management in boreal forests.
This project is supervised by Hubert Morin (UQAC) and co-supervised by Miguel Montoro Girona (SLU).
