Recent and projected future wildfire trends across the ranges of three spotted owl subspecies under climate change

Publications Posted on: April 08, 2019
A major task for researchers in the twenty-first century is to predict how climate-mediated stressors such as wildfires may affect biodiversity under climate change. Previous model predictions typically did not address non-stationarity in climate-fire relationships across time and space.

Will landscape fire increase in the future? A systems approach to climate, fire, fuel, and human drivers

Publications Posted on: February 13, 2019
The extent of the Earth's surface burned annually by fires is affected by a number of drivers, including but not limited to climate. Other important drivers include the amount and type of vegetation (fuel) available and human impacts, including fire suppression, ignition, and conversion of burnable land to crops.

Vegetation, topography and daily weather influenced burn severity in central Idaho and western Montana forests

Publications Posted on: October 06, 2015
Burn severity as inferred from satellite-derived differenced Normalized Burn Ratio (dNBR) is useful for evaluating fire impacts on ecosystems but the environmental controls on burn severity across large forest fires are both poorly understood and likely to be different than those influencing fire extent.

The relationship of large fire occurrence with drought and fire danger indices in the western USA, 1984-2008: The role of temporal scale

Publications Posted on: September 23, 2015
The relationship between large fire occurrence and drought has important implications for fire prediction under current and future climates. This study’s primary objective was to evaluate correlations between drought and fire-danger- rating indices representing short- and long-term drought, to determine which had the strongest relationships with large fire occurrence at the scale of the western United States during the years 1984-2008.

Climate change impacts on fire regimes and air quality in northern Eurasia

Projects Posted on: March 27, 2015
Global surface temperatures have increased about 0.89°C during the period from 1901 to 2012. Northern Eurasia has experienced the greatest temperature increase to date and is projected to continue experiencing the largest temperature increase globally.

An analysis of controls on fire activity in boreal Canada: comparing models built with different temporal resolutions

Publications Posted on: September 19, 2014
Fire regimes of the Canadian boreal forest are driven by certain environmental factors that are highly variable from year to year (e.g., temperature, precipitation) and others that are relatively stable (e.g., land cover, topography).

Scale-dependent controls on the area burned in the boreal forest of Canada, 1980-2005

Publications Posted on: October 05, 2011
In the boreal forest of North America, as in any fire-prone biome, three environmental factors must coincide for a wildfire to occur: an ignition source, flammable vegetation, and weather that is conducive to fire. Despite recent advances, the relative importance of these factors remains the subject of some debate.
