Shrub control associated with reforestation in high-severity burn areas promotes understory diversity: Research Brief

Shrub control associated with reforestation in high-severity burn areas promotes understory diversity: Research Brief

Bohlman et al. conducted a study looking at the effects of post-fire reforestation on understory plant species richness and composition, as well as stand structure. Three different aged fires were selected to assess the role of time since fire on the different stand components.

Influence of post-fire vegetation and fuels on fire severity patterns in reburns: Research Brief

Influence of post-fire vegetation and fuels on fire severity patterns in reburns: Research Brief

Results from a 2016 study by Coppoletta and others suggests that in areas where fire regimes and forest structure have been dramatically altered, contemporary fires have the potential to set forests on a positive feedback trajectory with successive reburns, one in which extensive stand-replacing fire could promote more stand-replacing fire.

Predicting Future Fire Regimes: Still a Long Way to Go: Research Brief

Predicting Future Fire Regimes: Still a Long Way to Go: Research Brief

In a review article by Jon Keeley and Alex Syphard, examples from California show that fire regimes are sensitive to geographic and seasonal variation in the climate signal and that many factors will confound the ability to model future conditions.

Wildfires Differences among Agencies and Ecoregions in the Sierra Nevada: Research Brief

Wildfires Differences among Agencies and Ecoregions in the Sierra Nevada: Research Brief

A 2012 study by Miller and others suggests that fire management approaches used by the National Park Service in Yosemite National Park could assist in the restoration and maintenance of Sierra Nevada forest ecosystems.

High Elevation Extremes Limit Alien Plant Success: Research Brief

High Elevation Extremes Limit Alien Plant Success: Research Brief

Why aren’t globally successful, weedy plant species generally found at high altitudes? This study suggests that it’s due to extreme abiotic conditions in association with the alien species’ life history traits, not a lack of opportunity.

Pratt’s Arguments Against “Light Burning” in 1911: Research Brief

Mr. Pratt in 1911 published an argument against the “light burning” practices of those days, claiming these small fires were unnecessary and only caused an expensive loss of merchantable lumber over the years. Like other light-burning advocates, he had no research on his side.

Restoring Desert Biocrusts after Severe Disturbances: Research Brief

Collaboratively with the National Park Service, the authors performed a study along Northshore Road in Lake Mead National Recreation Area (eastern Mojave Desert, Nevada) to develop biocrust restoration strategies. Results and management recommendations for the most effective restoration methods are discussed.

"Light Burning" Debate in the early 1900's: Research Brief Series

In the early 20th century, there was an intense controversy over systematic “light burning, the practice of using cool fire as a management tool (similar to what we call prescribed fires today). These practices for fire control were highly debated before fire suppression policies overwhelmingly prevailed. Presented here is a series of research briefs that review publications from this controversy at this interesting look into history.

Why Should Old-growth Chaparral Be Protected? Research Brief

Why Should Old-growth Chaparral Be Protected? Research Brief

Old-growth chaparral systems are biodiversity hotspots that need to be protected for legal, functional, and ethical reasons. This learning module describes these Mediterranean Type Climate systems from a global perspective so that we can better protect them.

Ecological Correlates With Resprouting and Seeding: Research Brief

Ecological Correlates With Resprouting and Seeding: Research Brief

In northern, southern, coastal, and interior California, examples exist of paired sibling Arctostaphylos subspecies exhibiting two alternate life strategies for surviving disturbance: resprouting and obligate seeding. This is a wonderful opportunity to observe how natural selection might favor one life strategy type over another, particularly in “an era of rapid climate change."

What affects fire behavior more, climate or fuels? Research Brief

What affects fire behavior more, climate or fuels? Research Brief

The authors examined the relationship between fuels and fire behavior by examining how fire suppression has affected fire severity in different forest ecosystems in California. The authors tested the hypothesis that fire behavior is limited by fuel availability in some California forests where climatic conditions during the fire season are nearly always conducive to burning and the primary limiting factor for fire ignition and spread is the presence of sufficient fuel.

Proximate Causes of Abrupt Fire-Regime Changes: Research Brief

Proximate Causes of Abrupt Fire-Regime Changes: Research Brief

In many past and present ecosystems, changes in animal, plant, and human communities have been more influential in rapid local fire regime disruption than climate. The good news is that, unlike climate change, these direct, proximate community causes can be practically addressed by fire and resource managers.

Understanding the Complex Nature of Resprouting: Research Brief

Understanding the Complex Nature of Resprouting: Research Brief

Resprouting plants are common throughout the world and resprouting is a familiar response to any kind of disturbance that kills living tissue. Resprouting is a seemingly simple trait that has complex underlying morphological and anatomical origins among diverse evolutionary lineages.

Evolution of Resprouting and Seeding by Fire: Research Brief

Evolution of Resprouting and Seeding by Fire: Research Brief

Some shrub species are obligate resprouters, some are obligate seeders, and others are facultative seeders, combining both resprouting and postfire seeding to various degrees. How could this diversity in fire response have evolved and how does it coexist?
