About Us There is a growing concern among scientists and forest stakeholders regarding the capacity of our forests to withstand increasing temperatures and water stress. In my lab, we use innovative experimental and observational methods to document the sensitivity and improve the adaptive capacity of eastern Canadian forests to climate change.

Loïc D'Orangeville
Associate Professor
BIO
Loïc D'Orangeville joined the Department of Wood and Forest Sciences at Laval University as an Associate Professor in 2024. He holds a BSc and a MSc in Biology from the Université de Montréal, with a PhD in Renewable Resource Sciences from McGill University. Prior to moving to Québec city, Loïc was professor at University of New Brunswick for six years after postdoctoral internships at Indiana University (USA) and Université du Québec à Montréal, and a visiting scholarship at Harvard Forest in 2017-2018.
Loïc has been involved in several climate change experiments in Eastern Canada, in controlled environments as well as in natural stands, to detect ecosystem vulnerability to global warming and associated increases drought. In complement, he has designed large-scale studies that use inventory-based tree-ring collections to detect climatic thresholds in the growth of dominant tree species.
When he's not working, he likes to pick mushrooms, practice kendo, play music, cook, and joke around.
Brittney Henry
M.Sc. 2026 - ongoing (University of New Brunswick)
BIO
Brittney completed a B.Sc. in Biology and Environmental Science at Mount Allison University. She spent many summers getting her hands dirty in community gardens and on farms before working at a tree nursery, which inspired her to pivot to the field of forestry. She enjoys moth watching, reading, gardening, and playing with dogs.
Brittney's research is focused on assessing drought tolerant traits in improved white spruce families across climates represented in the TransX trial network. Specifically, she will measure growth, mortality, and other key ecophysiological traits associated with drought response. She hopes this research will contribute to the climate change angle of tree improvement research in New Brunswick.
Lynsay Spafford
Postdoc 2024 - ongoing (University of New Brunswick)
BIO
Lynsay completed her Ph.D. in Environmental Science at the Memorial University of Newfoundland, and B.Sc.Hons. in Environmental Sciences at St. Francis Xavier University. She has worked as a Research Consultant for the Swiss Federal Institute of Forest, Snow, and Landscape Research, and also as a technician for the e-phenology lab in Universidade Estadual Paulista in Brazil. During her PhD, Lynsay collaborated to establish and expand the Acadian Phenocam Network across the Maritimes, tracking dynamic climate change impacts to forest ecology. In her postdoc work, Lynsay plans to further expand this network and enhance monitoring capacity to include growth. Her work aims to track and anticipate the impacts of climate change on forest health and climate change mitigation potential. In her free time, Lynsay enjoys playing fiddle, spending time outdoors, baking, and travelling.
Sébastien Dumont
Ph.D. Forest Sciences 2023 - ongoing (Laval University)
BIO
Sébastien completed his B.Sc. in Forest Environment and Management and his M.Sc. in Forest Sciences at Laval University in Quebec City. During his studies, he worked for the Quebec Ministry of Forests, where he was involved in several studies on northern hardwood silviculture. He also completed an internship at Forest Research (UK) in 2022.
Sébastien is working on the effects of acute climatic events such as drought and spring frost on tree growth in boreal and temperate forests. He uses a mix of dendrochronology, field experiment and growth models to quantify the effects of these events and to assess their impact on growth projections. His goal is to provide data for climate-sensitive growth models and recommendations for adaptive silviculture.
When he's not working, he enjoys hiking, reading, photography, and learning new board games.
Sandy Grimm
PhD Forestry 2026 - ongoing
BIO
Sandy holds an engineer’s degree in landscape management and nature conservation and a MSc in Forestry from University of New Brunswick. After spending most of her professional life with insects and mites and their usage in biological plant protection, she started to work with trees at a forest tree nursery in 2019, where she developed a strong interest in understanding the factors influencing the seedlings’ health and growth.
Sandy’s research focuses on understanding and predicting seed production in natural stands and seed orchards in Quebec. When she is not working, she likes spending time with her family and growing vegetables in their garden.
Jacob Ravn
BIO
Jacob has always been passionate about ecology and forestry. He pursued these interests while working in positions ranging from riparian restoration to wildfire fighting. He obtained his B.Sc. and M.Sc. in Forestry degree from the University of New Brunswick in Fredericton, New Brunswick.
Jacob is currently researching the impacts of climate change induced warming and drought on the growth of balsam fir across its entire range. To achieve these objectives, he will utilize growth chambers and greenhouses to expose balsam fir seedlings of varying provenance locations to drought and temperature increases. He hopes that the data procured from this research will allow for a better understanding of the population and ecological shifts that climate change will have on the forests and stands within Atlantic Canada. When he isn’t obsessing over trees, Jacob loves to cook, explore the outdoors, expand his worldly knowledge, and take frequent naps.
Mackenzie Good
M.Sc. Forestry 2024 - ongoing
BIO
Mackenzie completed her B.Sc. in Environment and Natural Resources at the University of New Brunswick in 2024. During the summer months throughout her Bachelor’s, she worked for the New Brunswick Department of Natural Resources and Energy Development and the Canadian Forest Service as a greenhouse technician growing trees. In her spare time, she enjoys watercolour painting, reading, and spending time with her family and friends.
Mackenzie is currently researching stress responses to warming and drought on many species and populations found within Eastern North America to inform assisted migration. This is being done through an ex-situ approach, where she is using phytotrons to conduct a controlled experiment with several temperature and drought treatments. In doing this, she is hopeful that she will contribute to developing assisted migration guidelines and therefore aid the forest production industry in utilizing species and populations adapted to a changing climate!
Taylor Bottoms-Cau
M.Sc. Forestry 2024 - ongoing
Taylor completed her Honours Specialization BSc in Biology with a Certificate in Forest Resource Management and Conservation at Nipissing University in 2023. Throughout her studies at Nipissing University she spent time working and volunteering as a research assistant on several projects, as well as completing an Honours Thesis project studying bryophyte diversity and cover on inactive forest roads in the Nipissing Forest.
At the University of New Brunswick, Taylor will be examining the interactions of drought and pre-commercial thinning on white spruce plantations using drone-based multispectral imaging and LiDAR at the ThiRST experiment site in northern New Brunswick.
In her free time Taylor enjoys reading, bird watching, and watching bad movies.
Malcolm MacDonald
Acadian Phenocam Network Field Technician
BIO
Malcolm has always had a passion for the outdoors and a desire to learn more about nature, stemming from a childhood spent hunting, fishing, and camping whenever he could. After nearly a decade as a finish carpenter, he developed a keen appreciation for the unique qualities of various tree species. During this time, he volunteered for five years with the Acadian Phenocam Network Project, where he utilized his skills to build and maintain essential infrastructure. Malcolm enjoyed this role, particularly the challenges posed by hurricanes and wildlife, all while exploring the remote back roads of Nova Scotia. As the network expanded and new infrastructure was implemented to monitor growth, he transitioned from a volunteer to a staff member of the APN.
In his spare time, Malcolm enjoys spending time in the forest, capturing wildlife and nature through photography, as well as hiking and camping. His other interests include cooking, reading, writing, and listening to classic rock ‘n’ roll.
