arrowDon McKenzie Presented Webinar on Consequences of Future Wildfire Smoke

Smoke from wildfires has adverse biological and social consequences, and various lines of evidence suggest that smoke from wildfires in the future may be more intense and widespread, demanding that methods be developed to address its effects on people, ecosystems, and the atmosphere. Earlier this month, Don McKenzie presented a webinar on the essential ingredients of a modeling system for projecting smoke consequences in a rapidly warming climate that is expected to change wildfire regimes significantly.

arrowDocumentation of Fire Effects Continues in Colorado

In Colorado Springs, Bob Vihnanek continues to conduct thorough technical discussions with the local firefighting first responders. This information will help to reconstruct the timeline of the movement of the 2012 Waldo Canyon Fire through the city, which informs research on the Joint Fire Science Program project to evaluate the effectiveness of mitigations activates in the wildland-urban interface. The work is done in cooperation with Alex Maranghides of the National Institute of Standards and Technology.



arrowLearning about Fuels and Consumption in the New Jersey Pine Barrens

In the New Jersey Pine Barrens, FERA’s field crew has been on the job measuring fuel consumption to aid research to relate LIDAR measurements to actual fuels. The Joint Fire Science Program supports Nick Skowronski of the Forest Services’ Northern Research Station in the evaluation and optimization approach to determining potential effectiveness of fuel treatments using both experimental data and modeling.



arrowFire Laboratories Collaborate to Share Research Results at Conference

Attendees at the May 2014 meeting in Missoula, “Large Wildland Fires: Social, Political, and Ecological Effects” will find information about fire research efforts featured in a single booth in the exhibitors hall. Information from the Missoula Forest Fire Laboratory and Pacific Northwest Fire Sciences Laboratory can be found there, as well as ….



arrowFuel Treatments and Landform Modify Landscape Patterns of Burn Severity in an Extreme Fire Event

Under a rapidly warming climate, a critical management issue in semiarid forests of western North America is how to increase forest resilience to wildfire. Susan Prichard and Maureen Kennedy, FERA cooperators at the University of Washington, evaluated relationships between fuel reduction treatments and burn severity in the 2006 Tripod Complex fires in Washington State and published their research results in the journal Ecological Applications.

arrowFuel Treatment Prescriptions Alter Spatial Patterns of Wildland Severity around the Wildland-Urban Interface During the Wallow Fire, Arizona, USA

Maureen Kennedy and Morris Johnson examine the spatial pattern of fire severity as the Wallow Fire move from wildland fuels into treated fuels. All fuel treatments demonstrated reduced fire severity before encountering homes, demonstrating that there are multiple paths to fuel treatment design around the wildland-urban interface.


Wildland Fire Emissions, Carbon, and Climate: Modeling Fuel Consumption

Roger Ottmar synthesized the current state of knowledge regarding fuel consumption, factors and variables that influence fuel consumption, systems currently available for predicting fuel consumption, and future direction in research to improve our knowledge and predictive capabilities for estimating greenhouse gases produced from wildfire.


arrowWildland Fire Emissions, Carbon, and Climate: Characterizing Fuels

The U.S. Forest Service Pacific Southwest Research Station’s David Weise and FERA’s Clint Wright synthesized the state of science regarding wildland fuels in the context of greenhouse gas, aerosol, and black carbon emissions. The synthesis examines the science that has been used and is being developed to characterize wildland fuels.



arrowFire Behavior in Masticated Fuels: a Review

Roger Ottmar joined with collaborators to produce this review of the current literature on fuels and fire behavior following mastication of forest fuels. They highlight the variation of fire behavior across ecosystems, and identify key science needs to better explain fire behavior and effects in these treatments.


arrowFuel Characteristic Classification System Version 3.0: Technical Documentation

If you’ve ever wanted to look “under the hood” of the Fuel Characteristic Classification System (FCCS) to see what and how it calculates fuel characteristics, wait no more. This general technical report provides detail on the calculation of the characteristics, surface fire behavior results, and each of the potentials. Dr. Susan Prichard led the team that compiled the many variables and equations.



arrowComparing Algorithms for Estimating Foliar Biomass of Conifers in the Pacific Northwest

Crystal Raymond and FERA author Don McKenzie compared five algorithms for estimating foliar biomass (FB) for seven common coniferous species in the Pacific Northwest. Algorithms based on diameter at breast height (DBH), or on DBH and height, consistently yield higher estimates of FB than algorithms based on sapwood area. At the tree level, differences between algorithms increased with increasing DBH for all species, but their order and magnitude differed by species. At the stand level, differences among algorithms were muted by the mix of species and diameter classes that contributed to total FB of stands of different seral stages and species composition. Significant differences among estimates of FB from different algorithms show the need for consistent methods for estimating FB for carbon accounting, tests of the sensitivity of ecosystem models to these differences, and more field observations to compare algorithms.
