Local forest structure variability increases resilience to wildfire in dry western U.S. coniferous forests. [PDF]

open access: yes, 2020
A 'resilient' forest endures disturbance and is likely to persist. Resilience to wildfire may arise from feedback between fire behaviour and forest structure in dry forest systems.

Estimating Leaf Bulk Density Distribution in a Tree Canopy Using Terrestrial LiDAR and a Straightforward Calibration Procedure

open access: yesRemote Sensing, 2015
Leaf biomass distribution is a key factor for modeling energy and carbon fluxes in forest canopies and for assessing fire behavior. We propose a new method to estimate 3D leaf bulk density distribution, based on a calibration of indices derived from T ...

A Full-Waveform Airborne Laser Scanning Metric Extraction Tool for Forest Structure Modelling. Do Scan Angle and Radiometric Correction Matter?

open access: yesRemote Sensing, 2020
In the last decade, full-waveform airborne laser scanning (ALSFW) has proven to be a promising tool for forestry applications. Compared to traditional discrete airborne laser scanning (ALSD), it is capable of registering the complete signal going through

Mathematical Modeling of Forest Fire Containment Using a Wet Line Ahead of the Combustion Front

open access: yesFire, 2023
The modern methods of predicting the fire front spread characteristics during forest fires have significant limitations. The main challenge is to adequately describe the impact of the flame length (reaching 10–15 m even during surface fires) on the fire ...

Physiological drought responses improve predictions of live fuel moisture dynamics in a Mediterranean forest. [PDF]

open access: yes, 2018
The moisture content of live fuels is an important determinant of forest flammability. Current approaches for modelling live fuel moisture content typically focus on the use of drought indices.

Fuel loads and fuel structure in Austrian coniferous forests

open access: yesInternational Journal of Wildland Fire, 2022
Understanding fires in temperate European coniferous forests is hindered by a lack of reliable field observations on fuel load and structure. Fuel load influences the spread, intensity and spotting distance of a surface fire, torching likelihood and potential carbon emissions.

Hypolipidemic activities of partially deacetylated α-chitin nanofibers/nanowhiskers in mice

open access: yesFood & Nutrition Research, 2018
Partially deacetylated α-chitin nanofibers/nanowhiskers mixtures (DEChNs) were prepared by 35% sodium hydroxide (NaOH) treatment followed by disintegration in water at pH 3–4.

Human ignitions on private lands drive USFS cross-boundary wildfire transmission and community impacts in the western US

open access: yesScientific Reports, 2022
Wildfires in the western United States (US) are increasingly expensive, destructive, and deadly. Reducing wildfire losses is particularly challenging when fires frequently start on one land tenure and damage natural or developed assets on other ...

Effect of fire spread, flame characteristic, fire intensity on particulate matter 2.5 released from surface fuel combustion of Pinus koraiensis plantation– A laboratory simulation study

open access: yesEnvironment International, 2022
PM2.5 is one of major pollutants emitted from forest fires. High PM2.5 concentration not only affects short-term human respiration health, but also poses a long-term threat to human cardiopulmonary functionality.
