My research mainly focuses on the interaction between natural disturbances and ecological processes at different spatial and temporal scales. I am particularly interested in long term response of Alpine and Boreal ecosystems to fire disturbance, including biodiversity response and ecosystem resilience aspects. I mainly study long-term ecological archives contained in natural sedimentary sites such as pollen, macroremains or charcoals  to understand ecological processes and vegetation dynamics at millennia time scale.

 Evrard obtained  a master’s degree in botany and phytotherapy (option Phytochemistry) from the University of Abobo-Adjame (Ivory Coast) and a Master in Ecology, Biodiversity (option tropical plant biodiversity) from the University of Montpellier (France). He is particularly interested by the interactions between climate, fire disturbances and forest dynamics in boreal and tropical zones with the objective of identifying mechanisms which lead to environmental changes on a global scale. The aim of his thesis is to highlight the Holocene changes in vegetation between the spruce-moss (closed canopy forests) and spruce-lichen (open canopy) forests and the factors underlying this dynamic in mosaic landscapes from the northern Quebec.

I obtained an Engineer degree in Agronomy with a major in Forestry and forest management from AgroParisTech Nancy.
During my studies, I have worked on the Spruce Budworm outbreaks and its consequences in tree ring growth in Black Spruce and Balsam Fir forests in Québec. The second internship consisted in understanding how climate change will influence the phenology of 10 tree productive species in France.
My thesis focuses on the reconstruction of ecosystem processes in eastern Québec since the deglaciation by using pollen and charcoals records from lake sediments. My aim is to calibrate bioproxies taphonomy using recent sediment analysis, remote sensing and field surveys. I have a strong focus on understanding quantitatively vegetation, fire and climate dynamics. Those results will help to assess future projections and models for guiding forest management.

During my undergraduate degree in environmental geography at UdeM, I had the opportunity to work on various problematic as : the urban heat island remote sensing, the bog ponds physico-chemical variability and the Holocene fire frequency evolution of the Gatineau Park. Now candidate for a graduate degree in Biology at UQAT and recipient of a BMP scholarship, I’m studying the Holocene sugar maple migration in Abitibi-Témiscamingue and the influence of fire disturbance on this species.
