Assistant Fire Management Officer, Eldorado National Forest, Placerville, Calif.; Soil Scientist, Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Glendora, Calif. Abstract: The use of prescribed fire in the chaparral could reduce the incidence and impacts of severe wildfires and enhance watershed resources. This paper describes the operatio...

Wildfires present a complex applied risk management environment, but relatively little attention has been paid to behavioral and cognitive responses to risk among public agency wildfire managers. This study investigates responses to risk, including probability weighting and risk aversion, in a wildfire management context using a survey-based experiment administered to federal wildfire managers....

INTRODUCTION Narrowing the awareness-preparedness gap in bushfires (wildfires) means that new strategies and tactics will be needed to improve human safety and survival in this increasingly frequent and severe globally significant natural hazard. One way to do this is to explore the peri-event experiences of novel demographic groups living and working in at-risk areas to determine how best to s...

We propose new summary statistics for intensity-reweighted moment stationary marked point processes with particular emphasis on discrete marks. The new statistics are based on the n-point correlation functions and reduce to cross J and D-functions when stationarity holds. We explore the relationships between the various functions and discuss their explicit forms under specific model assumptions...

Understanding the fire prediction capabilities of fuel models is vital to forest fire management. Various fuel models have been developed in the Great Xing'an Mountains in Northeast China. However, the performances of these fuel models have not been tested for historical occurrences of wildfires. Consequently, the applicability of these models requires further investigation. Thus, this paper ai...

The Albian amber from Spain presently harbors the greatest number and diversity of amber adult fossil snakeflies (Raphidioptera). Within Baissopteridae, Baissoptera? cretaceoelectrasp. n., from the Peñacerrada I outcrop (Moraza, Burgos), is the first amber inclusion belonging to the family and described from western Eurasia, thus substantially expanding the paleogeographical range of the family...

The idea of using natural patterns as guides for policy and practices continues to gain favour in forestland management. Towards this, research activities in the boreal have been focusing on the patterns and processes of wildfires over the last 15-20 years. This project is the fourth phase of a long-term research study looking at natural wildfire patterns across the forested areas of Alberta an...

Crown fires associated with extreme fire severity are extremely difficult to control. We have assessed fire severity using differenced Normalized Burn Ratio (dNBR) from Landsat imagery in 15 historical wildfires of Pinus halepensis Mill. We have considered a wide range of innovative topographic, fuel and fire behavior variables with the purposes of (1) determining the variables that influence f...

We studied the sources, compositions and size distributions of aerosol particles during long-range transport (LRT) PM2.5 episodes which occurred on 12–15 August, 26– 28 August and 5–6 September 2002 in Finland. Backward air mass trajectories, satellite detections of fire areas and dispersion modelling results indicate that emissions from wildfires in Russia and other Eastern European countries ...

Introduction Alberta has an extensive system in place for detecting wildfires, including a network of over 130 lookout sites strategically placed throughout the forest protection area (SRD 2001). The lookout personnel undergo training when hired and are tested annually. Simulated wildfires must be used to test and train personnel. These mock wildfires have been produced in the past by igniting ...
