What is it about?

Our study shows how tree growth responses to freeze exposure vary in direction and magnitude by clade and species, but also with leaf-out strategy, tree age and size, and environmental factors. We explored how cold hazards such as freezing exposure impacts tree growth using tree-ring data of over 35,000 individuals from 57 species at 4,300 sites across Canada.

Why is it important?

Our findings highlight the value of using species-specific climate-growth relationships to refine predictions of forest carbon dynamics.


This article is the culmination of many years of research and efforts of our scientific predecessors who collected and analyzed these dendrochronological data. It is also a demonstration of the added value of having tree samples collected during forest inventories.
