Aim Increasing aridity has driven widespread synchronous fire occurrence in recent decades across North America. The lack of historical (pre‐1880) fire records limits our ability to understand long‐term continental fire‐climate dynamics. The goal of this study is to use tree‐ring reconstructions to determine the relationships between spatiotemporal patterns in historical climate and widespread fire occurrence in North American...

Recently burned boreal forests have lower aboveground fuel loads, generating a negative feedback to subsequent wildfires. Despite this feedback, short‐interval reburns (≤20 years between fires) are possible under extreme weather conditions. Reburns have consequences for ecosystem recovery, leading to enduring vegetation change. In this study, we characterize the strength of the fire‐fuel feedback in recently burned Canadian bo...

Wildfires in the boreal forest of North America are generally stand renewing, with the initial phase of recovery often governing the vegetation trajectory for decades. Here, we investigated post-fire vegetation changes in dry boreal forests of the Northwest Territories, Canada, during the first 5 years following the unusually severe 2014 wildfire season. We sampled post-fire tree regeneration and the understory plant community...

Aim Studies of fire activity along environmental gradients have been undertaken, but the results of such studies have yet to be integrated with fire‐regime analysis. We characterize fire‐regime components along climate gradients and a gradient of human influence. Location We focus on a climatically diverse region of north‐western North America extending from northern British Columbia, Canada, to northern Utah and Colorado, USA...
