In a recent issue of the journal Ecological Applications, USGS scientist Dr. Matthew Brooks reports new information on temperature patterns during experimental fires, and the effects of these variable fire temperatures on annual plants in the Mojave Desert.

It is concluded that there is a wealth of information on factors affecting fire size in southern California that make it unnecessary to base fire management in the region on questionable comparisons with Baja California.

Two important questions about fire severity that are investigated are: to what extent can fire severity be measured by remote sensing indices, and do fire severity measurements predict ecosystem responses in vegetation recovery.

According to a recent statewide FRID (fire return interval departure) analysis for USFS and some NPS lands, there are two distinct California fire regimes.

Temporal and spatial patterns of burning can affect the invasion risk and prevalence of alien plants in California as explained in a book chapter in The Landscape Ecology of Fire.

In a comparative study of fire sizes north and south of the U.S./Mexican border Minnich (1983) demonstrated differences during a nine year period in non-‐forested landscapes that included chaparral, sage scrub and annual grassland.

In the April issue of Conservation Biology, Keeley considers the impact of six fire management practices on alien invasions: fire suppression, forest fuel reduction, prescription burning in crown fire ecosystems, fuel breaks, targeting noxious aliens, and postfire rehabilitation.

USGS research botanist Matt Brooks and National Wildlife Refuges invasive species coordinator Michael Lusk have compiled a handbook titled Fire Management and Invasive Plants, with support from the U.S. Fish and Wildlife Service National Refuge System, USGS and the Joint Fire Science Program.

This paper evaluated the current usage of the terms "fire frequency" and "fire intensity" and agrees the terminology requires clarification but advocates retention of these terms.

Cook used the 1953 wildfire in Berkeley, CAas an opportunity to research the effects of fire on rodent populations in California grasslands and “brushlands.”

Dendrochronology and other methods were used to reconstruct the fire history from 1500 through 2006 in the vicinity of Mt. Irish.

Mastication is an increasingly popular fuels treatment, particularly in densely populated or otherwise complex areas where prescribed fire would be difficult or impossible to implement.

In Diversity and Distributions, the authors found that determining the factors responsible for community-scale plant diversity in California shrublands is a multifaceted problem.

In central coastal California, a complex mosaic of vegetation types appears to be largely unrelated to substrate and more strongly determined by disturbance history, in particular human induced changes in fire frequency.

In response to a recent criticism of the practice of prescription burning published in Trends in Plant Science, USGS scientist Jon Keeley and colleagues from Spain, South Africa and Australia contend that when applied within the context of a landscape’s natural fire regime, prescribed burning remains a viable treatment to manage native plant ecosystems.

This research project assessed the accuracy of three different smoke models (CALPUFF, DAYSMOKE, and CMAQ) at predicting PM2.5 emissions from prescrubed burn and wildfire events in the southeastern United States. Past fire events were modeled, and models were compared to observed data from the actual events.

Models of fisher habitat selection and metapopulation dynamics in the southern Sierra Nevada suggest the negative effects of fuel treatments on fisher habitat suitability and population size are generally smaller than the long-‐term positive effects of fuel treatments that reduce wildfire risk and severity.
