Quantifying fire trends in boreal forests with Landsat time series and self-organized criticality

Publications Posted on: May 15, 2020
Boreal forests are globally extensive and store large amounts of carbon, but recent climate change has led to drier conditions and increasing fire activity. The objective of this study is to quantify trends in fire size and frequency using data spanning multiple scales in space and time. We use multi-temporal Landsat image compositing on Google Earth Engine and validate results with reference fire maps from the Canadian Park Service.

First-year post-fire erosion rates in Bitterroot National Forest, Montana

Publications Posted on: March 04, 2020
Accelerated runoff and erosion commonly occur following forest fires due to combustion of protective forest floor material, which results in bare soil being exposed to overland flow and raindrop impact, as well as water repellent soil conditions.

Wildland fire: Impacts on forest, woodland, and grassland ecological processes [Chapter 3]

Publications Posted on: September 10, 2019
Fire is a natural disturbance that occurs in most terrestrial ecosystems. It is also a tool that has been used by humans to manage a wide range of natural ecosystems worldwide. Wildland fire covers a spectrum from low severity, localized prescribed fires, to landscape-level high severity wildfires.

Relationships between satellite-based spectral burned ratios and terrestrial laser scanning

Publications Posted on: May 30, 2019
Three-dimensional point data acquired by Terrestrial Lidar Scanning (TLS) is used as ground observation in comparisons with fire severity indices computed from Landsat satellite multi-temporal images through Google Earth Engine (GEE). Forest fires are measured by the extent and severity of fire.

Scaling nonreactive cross flow over a heated plate to simulate forest fires

Publications Posted on: October 05, 2018
The paper reports visualization of the flow of smoke over a flat surface inside of a low-speed wind tunnel. A heating plate flush mounted on the wind tunnel floor simulated a spreading line fire that produces uniform heat flux under constant wind speed condition.

Yes folks, that was a forest fire

Documents and Media Posted on: October 03, 2018
There's no mistake about it, fires have been burning all week on a mountain above Coram. But if there seems to be little concern among forest officials, it may be because U.S. Forest Service employes set them. Document Type: Other Documents

After the burn: Assessing and managing your forestland after a wildfire

Documents and Media Posted on: October 03, 2018
Fire in the forest. Though a natural part of the ecosystems of the Inland Northwest, it is one of the most feared, fought, and controversial components of our physical environment. Encompassing a large portion of the interior western United States, the landscapes of this region were born of volcanic eruptions, molded by glaciers and floods, and refined by frequent wildfires.Document Type: Other Documents

Fire ecology of the forest habitat types of eastern Idaho and western Wyoming

Publications Posted on: April 17, 2017
Provides information on fire as an ecological factor in the forest habitat types occurring in eastern Idaho and western Wyoming. Identifies Fire Groups based on fire's role in forest succession. Describes forest fuels and suggests considerations for fire management.

Rapid-response tools and datasets for post-fire remediation: Linking remote sensing and process-based hydrological models

Publications Posted on: January 06, 2017
Post-wildfire flooding and erosion can threaten lives, property and natural resources. Increased peak flows and sediment delivery due to the loss of surface vegetation cover and fire-induced changes in soil properties are of great concern to public safety. Burn severity maps derived from remote sensing data reflect fire-induced changes in vegetative cover and soil properties.

Valuing morbidity effects of wildfire smoke exposure from the 2007 Southern California wildfires

Publications Posted on: October 07, 2016
This study estimated the economic costs associated with morbidity from the wildfires that occurred in 2007 in southern California. We used the excess number of hospital admissions and emergency department visits to quantify the morbidity effects and used medical costs to estimate the economic impact.
