New paper out! Using tree rings, fire records, Landsat biomass data, and SEMs, we show that atmospheric dryness acts as a coordinating driver of boreal forest dynamics, raising questions about the extent to which growth gains can offset increasing fire-driven biomass losses doi.org/10.1071/WF25...

Atmospheric dryness as a coordinated driver of fire activity and biomass accumulation in northwestern boreal Canada

Rising vapor pressure deficit in northwestern boreal Canada is linked to increased burned area and reduced tree growth, with indirect effects on biomass ac

Canada’s forests are losing their ability to bounce back from drought—and we now have the data to show it - Using tree-ring data from 40,000+ trees across 4558 plots and 23 species, we explored how trees responded to drought over the past century In GCB onlinelibrary.wiley.com/doi/10.1111/...

Long‐Term Temporal Divergence in Post‐Drought Resilience Decline Between Deciduous and Evergreen Tree Species

Severe drought increasingly threatens the resilience of forest biomes worldwide. Using a tree-ring database from Canadian forests, encompassing 40,147 trees across 4558 plots and 23 species, we analy...

New paleofire study! Spring droughts have intensified over the past 250 years, reshaping fire seasonality in eastern Canada. Spring is now nearly as flammable as summer, driving infrequent but large and severe fires 🌲🔥 onlinelibrary.wiley.com/doi/10.1111/...

Drying Spring Accelerates Transitions Toward Pyrogenic Vegetation in Eastern Boreal North America

Over the past 8000 years, spring climatic conditions, particularly drought, have been the primary driver of wildfire dynamics in eastern boreal North America. Increasing spring dryness over the last ....
