Behavior and effects of prescribed fire in masticated fuelbeds: Research Brief
/The authors conducted prescribed burns in two masticated areas in northern California to assess fire effects in treated stands, compare fire behavior and effects with outputs from commonly used models, and evaluate the ability of mastication to increase stand resilience under a range of hypothetical wildfire scenarios.
Read MoreBasic principles of forest fuel reduction treatments: Research Brief
/In this paper, Agee and Skinner reviewed related literature, simulated fire behavior in different treatment types, and considered five real-‐world examples of fuels treatments and wildfire. Using these methods, they distilled a set of basic principles underlying effective treatments that reduce fuels and limit wildfire severity and extent.

Bark Beetle Responses to Differences in Forest Structure and the Application of Prescribed Fire in Interior Ponderosa Pine: Research Brief
/This study assessed the effects of both prescribed burning and stand structure management through thinning on bark beetle activity and associated levels of tree mortality.
Read MoreBalancing the Carbon Costs and Benefits of Fuels Management: Research Synthesis
/This 2011 review synthesizes the growing body of scientific literature on the carbon balance of fuel treatments (i.e. the ability of treatments to achieve net carbon offsets.) The purpose of this synthesis is to highlight research relevant to forest managers and policymakers interested in the potential for forest management to contribute to climate change solutions.

Are Large Fires the Result of Fire Suppression? Research Brief
/This paper tests hypotheses pertaining to the impact of past fire suppression on southernCalifornia shrubland fire regimes.
Read MoreAnnual Growth Rings Reliably Tell Age of Chaparral: Research Brief
/This project verified the common assumption that annual growth rings can be used to determine age in California’s woody chaparral species.
Read MoreAn Early View on Stopping Wildfire Conflagrations: Research Brief
/With dangerous chaparral fires on the rise in the 1970’s, Clive Countryman asks and answers, “[Must] such [conflagrations] be accepted as inevitable in southern California? I think not!” And he outlines a set of fuel modification solutions...

A Snapshot of Fire Activity Prior to Fire Suppression: Research Brief
/This 1987 paper by Richard Minnich summarizes newspaper accounts for selected fires between 1868 and 1900 in the San Gabriel Mountains of southern California, and describes in detail the behavior of three summer fires in 1896, 1898 and 1900 on Mt. Wilso.
