New Extension Note!

To understand how forests respond to the more frequent and severe droughts across Canada, our lab is leading the ThiRST (Thinning to Reduce Stress) experiment. Congrats to Chloe Larstone Hunt for publishing this Extension Note on the challenges of leading such a large scale outdoor experiment! Link Here.

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. Access the video here!

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.


January 20, 2020

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.

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!


Lab news


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 tree species to climate change.
