Living things change constantly, as do communities of living things. In a forest, where individual trees can live for centuries and new plants replace old plants, it is not easy to visualize the changes that occur over time. This photoseries… more

Experiments to Improve Agricultural Smoke Decision Support Tools Agriculture is a vital part of the Northwest’s economy and is critical to the region’s rural communities. The production cycle of cereal crops and grasses, which are important… more

Predicting plant species shifts under changing climates using bioclimatic modeling of potential vegetation types Land managers need new tools for accounting for novel futures due to climate change. Species distribution modeling has been used… more

Image The BehavePlus fire modeling system is a Windows®-based computer program that can be used for any fire management application that needs to calculate fire behavior. It uses specified fuel and… more

Airborne Experiments to Characterize the Emissions of Biomass Burning in Mexico Biomass burning is the largest source of primary, fine carbonaceous particles and the second largest source of trace gases in the global atmosphere. Emissions from… more

Northern Eurasia covers 20% of the global land mass and contains 70% of the boreal forest. During certain times of the year, black carbon (BC) in smoke plumes at high latitudes may be transported and deposited on Arctic ice, thereby accelerating ice… more

Many scientists from the Fire, Fuel, and Smoke program are intimately involved with various aspects of fire management, including both prescribed fires and wildfires. Not only do these activities provide operational experience and the opportunity to… more

Understanding Burning Rate and Residence Time of Porous Fuel Beds Using Wood Cribs The fire spread process is fundamentally a series of ignitions, where a parcel of fuel ignites and burns at a particular rate, heating the neighboring fuel parcel… more

California is currently in the midst of a record-breaking drought and its forests are undergoing massive die-offs. This extensive tree mortality will drastically alter fuel loads, likely changing fire behavior and severity in fire-prone ecosystems… more

Fire and forest histories of central Oregon from tree rings Central Oregon currently lacks the site-specific fire and forest histories that are necessary for scientifically based land-management planning in the region. For a region with such… more

Wildland fire management teams can be faced with the potential for fires to damage power transmission or telecommunication lines. The damage can be severe enough to cause failure of the system which can have critical implications to public safety.… more

Condition of live fire-scarred ponderosa pine twenty-one years after removing partial cross-sections Ponderosa pine is widely distributed in fire-dependent ecosystems across western North America. Some individuals of this long-lived species have… more

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.  These fine fuels are highly efficient at convective heat transfer,… more
