Changes in fuel loading and conifer mortality risk factors due to bark beetles and drought in California.
Lodgepole pine forest host characteristics influence mountain pine beetle outbreak severity in the Northern Rocky Mountains.
Wildland fires emit significant amounts of greenhouse gases, particulate matter, and ozone precursors. This can have a significant negative effect on public health at multiple scales.
FPARDY (Fuel PARticle DYnamics), is one of many new efforts to explore surface fuel characteristics at the particle, layer, and fuelbed levels across major forest ecosystem types in the US northern Rocky Mountains (NRM) to develop a set of products that integrate these findings into standard fuel applications.
Recent research conducted at the Missoula Fire Lab has found that the amount of radiant heat in wildland fires is not sufficient to ignite fine fuel particles such as needles and grasses. Understanding the ignition process due to convective heating will allow for better prediction of the transition from surface to crown fire and crown fire spread, two aspects of wildland fire behavior that are largely misunderstood. Experiments are underway to determine if and how ignition due to convective heating is different than that from radiative heating.
Wildfire smoke can trigger severe pollution episodes with substantial impacts on public health.
