Loïc D'Orangeville interviewed by The Narwhal

Could 80,000 family woodlot owners be the key to saving the Acadian forest? Only remnants of this carbon-rich forest in the Maritimes remain after centuries of clear-cutting. Thousands of family forest owners have a stake in its survival. The question is: can they earn revenue from its protection rather than its destruction?

Loïc D'Orangeville appears in Our Changing Forest

In these informational videos, researchers, ecologists and forestry professionals were consulted to understand how the changing climate will affect New Brunswick’s forests, and how we can manage our forests for climate resilience. Produced by the New Brunswick Federation of Woodlot Owners, in partnership with Community Forests International and with the support of Environment and Natural Resources in Canada.

Fully funded MScF position in ecological modeling

We're now accepting applications from qualified candidates for a 2-year, fully funded Masters of Science in Forestry position focused on process-based modeling of forest landscapes in P.E.I. National Parks under climate change and forest management. This is a joint project between the Canadian Forest Service, Parks Canada, and the University of New Brunswick led by Dr. Anthony R. Taylor and myself. Details here.

Welcome to Martina Sánchez-Pinillos, a new postdoc from Spain!

Martina will look into the effects of interacting disturbances, namely water deficit and insect outbreaks, on boreal forest dynamics across Canada. Martina is developing new methodological approaches to detect forest resistance and resilience using national forest inventories. Welcome to the lab Martina! Full bio here.

Welcome to Jessé Moura, a new MScF student from Brazil!

Jessé will apply dendrochronology approaches to 50-yr-old provenance trials from New Brunswick to study population variations in climate responses. This knowledge will help us compare the capacity of Acadian species for assisted migration in a climate change context. Welcome Jessé! Full bio here.

Our lab featured in a new documentary on climate change and NB forests

This documentary was produced by Gaetan Pelletier, Executive Director of NHRI, and directed by Mathieu Germain with the assistance of Tanguy Locqueneux. The video documentary delves into the subject of climate change, its potential effects on our forests and what can, and should, be done to adapt. CLick HERE for full documentary!

Alexandra Villiard at UNB for a week of data analysis

Alex is a MSc student based in Montreal and co-supervised by Dan Kneeshaw (Université du Québec à Montréal) and Loïc D'Orangeville here at UNB. Her MSc project focuses on boreal balsam fir stand responses to drought and the roles of timing, tree size and competition. Full bio here.

Observations of rapid growth increase in southern Asian boreal forests now published in Global Change Biology

This work was lead by colleague Xianliang Zhang, of Hebei Agricultural Unviersity (China), during his stay at Harvard Forest. Results suggest that the warming-driven earlier growth onset allows trees to take advantage of snowmelt water, leading to massive gains in recent growth. Paper can be found here.

The D'Orangeville lab at NAFEW 2019

At the North American Forest Ecology Workshop, in Flagstaff (Arizona), Loïc D'Orangeville presented his results on the phenology of stem growth for 15 different tree species from Harvard Forest (MA). A great meeting held in the middle of the Ponderosa pine forest!

Megan Doyle joins the lab!

Megan will be our new lab manager for the 2019 field season. She will supervise the installation of new monitoring plots and help revisit old provenance studies at Acadia Research Forest. She will also help set up the wood analysis lab here in the Faculty. Her bio can be found here.

Loïc D'Orangeville talks at Québec Forest Research Meeting Carrefour de la Recherche Forestière in Québec City, Canada.

The anticipated rise in temperatures is likely to upset the growth of the Quebec forest. We presents results from our lab where the vulnerability of Eastern Canadian forests is documented by analyzing their response to past climate.

Lab study named one of top 10 discoveries of 2018

Our research has been selected as one of 10 Discoveries of the Year 2018 by Québec Science magazine. In this paper, done in collaboration with colleagues from Québec and the US, we used large tree-ring collections to project the effects that climate change on Eastern Canada’s boreal forest.

Silv@21: a national workshop on adapting silviculture to climate change in Montréal

Loïc D'Orangeville attended a NSERC-sponsored worshop organized by the Canadian Wood Fibre Centre and FPInnovations to coordinate a national research initiative to support the resilience and transition of Canadian forests in the face of global changes to meet the need for sustainable fibre. Representatives of each Canadian province, of major forest industry players and academia discussed during two days the research priorities, potential partners and future directions.

Vegetation Management workshop in Debert (NS)

Loïc D'Orangeville presented the research done in the lab to representatives of the Nova Scotia Department of Lands and Forestry (NSLF) during a workshop on Vegetation Management organised by NSLF and FPInnovation. The goal of the workshop was to better understand the research needs of the province following the release of the Lahey report.

Understanding Northern Latitude Vegetation Greening and Browning workshop in Washington D.C. (USA)

Loïc D'Orangeville attended this two-day workshop hosted by Canada and the US National Academies of Science. The goad was to bring together experts to discuss patterns and drivers of tundra and boreal forest vegetation productivity; methods and tools for evaluating vegetation patterns and changes; and implications for vegetation change. Great meeting, and special thanks to Canada's Polar Research Board for the invitation!




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 adaptive capacity of eastern Canadian tree species to climate change. Our focus is on the roles that species and environmental drivers play, at multiple spatial scales, in shaping tree growth response to a warming climate.
