The ability of chaparral species to persist following drastic removal treatments is a function of their life history characteristics and pre-‐treatment abundance.

In this paleoecology study of sediments at Point Reyes National Seashore (PORE), Scott Anderson documented changes in vegetation resulting from climate, people and fire over the past 15,000 years.

Climate change in California is likely to lead to a decline in alpine/subalpine and conifer forest, woodland, and shrubland extent while promoting grassland dominance.
Read MoreLarge fire events were a normal part of southern California’s natural history based on charcoal evidence.
Read MoreStand-replacing patch size was highly variable in a high elevation mixed conifer forest in the Sierra Nevada with a range of variation dominated by many small patches < 10 acres (4 ha) and few large patches >148 acres (60 ha).

This research brief discusses the changes in soil moisture after chaparral was removed in the long and short term.

Large, high-intensity wildfires are a natural feature of southern California landscapes and are not directly the result of past fire suppression activities.

This report presents a model for manipulating chaparral sites to be more productive for wildlife.

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 MoreIn 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.

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 MoreThis 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.

This brief summarizes fire ecology and management issues in California mixed-conifer forests for an audience without a background in fire, including the general public and media.

This paper tests hypotheses pertaining to the impact of past fire suppression on southernCalifornia shrubland fire regimes.
Read MoreThis project verified the common assumption that annual growth rings can be used to determine age in California’s woody chaparral species.
Read MoreWith 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...

Alien plants and fire have recently been recognized as significant land management problems in the Mojave and Colorado deserts, especially as they relate to management of the federally threatened desert tortoise.

This study looked at alien plant invasion in chaparral and sage scrub ecosystems over a period of five years after fire across a six-county area in southern California.
Read MoreExtreme fire intervals are one obvious concern for managers of fire dependent species such as the serotinous knobcone pine (Pinus attenuata).

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.
