Burn severity and fire history in the northwestern Canadian boreal forest: drivers and ecological outcomes
DownloadSpring 2019
Wildfire is the dominant stand-renewing disturbance in the northwestern Canadian boreal forest. Fires burn extensive areas in Canada, disturbing an average of 1.96 Mha yr−1, primarily in the boreal zone. Fires generally occur every ~30 – > 200 years in this region, due in part to a lack of fuel...

Effects of burn severity and time since fire on songbird communities in the northern boreal forest
DownloadFall 2018
Wildfire shapes the boreal ecosystem in western Canada and thereby enhances and diminishes important breeding habitat for many songbird species. Two aspects of wildfire, burn severity and time since fire, fundamentally alter the forest structure that songbirds use. The objectives of this study...

Fall 2021
The world’s forests are highly fragmented by linear disturbances, many of which have failed to recover decades after abandonment. Lack of recovery is common, most notably in xeric and hydric forests. Possible mechanisms for this lack of recovery are: life history traits of local species, lack of...

Out of the Dark, into the Light? Influence of Wildfire and Thermokarst on Greenhouse Gas Fluxes from Boreal Peat Landscapes near the southern Limit of Permafrost
DownloadFall 2024
Wildfire and permafrost thaw have been common disturbances in the boreal zone for millennia and are now intensified by warming due to human-made climate change. The Taiga Plains ecozone in northwestern Canada is warming at a faster rate than other regions. In this ecozone, permafrost is found at...

Spring 2022
In the boreal biome of North America, large wildfires usually leave behind residual patches of unburned vegetation, termed refugia, which can strongly affect post-fire ecosystem processes. While topographic complexity is a major driver of fire refugia in mountainous terrain, refugia and fire...

Predicting Fuel Characteristics of Black Spruce Stands Using Airborne Laser Scanning (ALS) in the Province of Alberta, Canada
DownloadFall 2020
Maps that describe the characteristics of live and dead biomass across large areas (i.e., fuel maps) are a critical input to a wide range of research models and decision support systems that aim to describe potential fire behaviour and inform fire management actions. As remote sensing...

Spring 2024
Fire weather indices are used by fire management agencies around the world to estimate potential wildfire danger. This allows for resources to be allocated effectively and to warn communities of potential wildfire hazards. Currently, monitoring and short-term forecasting of fire weather depends...

Fall 2020
Fire and insect outbreaks are the two leading natural disturbance factors affecting Canadian forests. Over the last 20 years Mountain Pine Beetle (Dendroctonous ponderosae Hopkins) has killed more than 50 percent of western Canada’s merchantable lodgepole pine (Pinus contorta) forests and spread...

Wildfire effects on net precipitation, streamflow regime and rainfall-runoff events in northern Rocky Mountain watersheds
DownloadFall 2022
In recent decades, severe wildfire in western North America has increased in frequency as a result of a warming climate and historical fire suppression, impacting an increasing amount of forested area. Reduced forest canopy interception and storage combined with soil water repellency and altered...
