Wildfire Suppression Contracting: The Effect of Local Business Capacity During Large Wildfires
Year: 2012
Contracting capacity and local capture can be the result of local economic conditions (supply side conditions) as well as agency contracting practices (demand side conditions). In order to capture contracts locally, local businesses that can perform the work need to exist, and past experience contracting with the federal government is a reasonable indicator of that capacity. To better understand local contracting capacity, we examined how local contract capture varied between wildfires and the relationship between local capture and contracting capacity measures. We investigated how the number…

Developing Socioeconomic Performance Measures for the Watershed Condition Framework
Year: 2012
The purpose of this report is to propose principles and strategies for creating socioeconomic performance measures, as well as identify potential measures that could be integrated into the WCF and other restoration frameworks in the short term. It also recommends a longer-term strategy to develop a social condition assessment and performance accountability system that could be paired with the WCF and terrestrial condition framework currently being developed. Finally, this report identifies potential barriers and challenges to adopting new performance measures, and potential approaches to…

Grazing After the Burn
Year: 2012
The rangelands and dry forests of Eastern Washington are considered “disturbance-driven” ecosystems. Disturbances are simply events that disturb normal ecosystem processes: nutrient and water cycling, plant growth and reproduction, animal interactions, etc. While all ecosystems experience some forms of disturbance, areas (like Eastern Washington) with extreme temperature variation, rough topography, scarcity of water, high soils variability, and high fire frequency experience more frequent and more severe disturbance than a Florida swamp forest, for an obvious example. Fire and grazing are…

Communication of the Role of Natural Variability in Future North American Climate
Year: 2012
As climate models improve, decision-makers' expectations for accurate climate predictions are growing. Natural climate variability, however, poses inherent limits to climate predictability and the related goal of adaptation guidance in many places, as illustrated here for North America. Other locations with low natural variability show a more predictable future in which anthropogenic forcing can be more readily identified, even on small scales. We call for a more focused dialogue between scientists, policymakers and the public to improve communication and avoid raising expectations for…

Long-term perspective on wildfires in the western USA
Year: 2012
Understanding the causes and consequences of wildfires in forests of the western United States requires integrated information about fire, climate changes, and human activity on multiple temporal scales. We use sedimentary charcoal accumulation rates to construct long-term variations in fire during the past 3,000 y in the American West and compare this record to independent firehistory data from historical records and fire scars. There has been a slight decline in burning over the past 3,000 y, with the lowest levels attained during the 20th century and during the Little Ice Age (LIA, ca.…

Characterizing Fire-on-Fire Interactions in Three Large Wilderness Areas
Year: 2012
The interaction of fires, where one fire burns into another recently burned area, is receiving increased attention from scientists and land managers wishing to describe the role of fire scars in affecting landscape pattern and future fire spread. Here, we quantify fire-on-fire interactions in terms of frequency, size, and time-since-previous fire (TSPF) in three large wilderness areas in Montana and Idaho, USA, from 1984 to present, using spatially consistent large fire perimeter data from the Monitoring Trends in Burn Severity (MTBS) dataset. The analysis is supplemented with less consistent…
