Post-fire Restoration Framework for California’s National Forests: Research Brief
/
Restoration of landscapes affected by uncharacteristically large and severe wildfires in California requires a science-based framework to address a complexity of issues and concerns. The authors describe a set of ecological restoration principles, a landscape assessment process, and a framework for decision-making to plan and implement restoration projects.
Read MoreAnalysis of past burn windows can help land managers plan and prioritize future burns : Research Brief
/
This study uses historical patterns of burn windows to predict burn window likelihood to inform prescribed burning planning and budgeting.
Read MoreEarly 1900’s forest structure in the mixed conifer forests of the Sierra Nevada, California: Research Synthesis
/
This synthesis summarizes six papers that use a variety of methods to reconstruct the historic forest structure and composition of the mixed-conifer forests of the Sierra Nevada.
Read MoreLonger-term impacts of fuels reduction treatments in the Lake Tahoe Basin: Research Brief
/
Employing a robust before-after-control-impact (BACI) study design, researchers assessed how thinning in forests altered forest structural conditions in the short- and longer-term in the Sierra Nevada.
Read MoreLinking diverse terminology to vegetation type-conversion, a complex emergent property: Research Synthesis
/
A variety of terms are applied to changes in ecosystems around the world to describe some aspect of long-lasting changes in plant communities. Here we evaluate a representative list of analogous terms for processes and patterns involved in vegetation type-conversion, highlighting similarities and differences.
Read MoreForest recovery following extreme drought in California: Research Brief
/
This study compares post-drought forests to historical forests to understand if the recent tree mortality event shifted forests closer to or further from resilient conditions.

Read MoreInteractions Between Fire and Climate in the California Sierra Nevada: Research Synthesis
/
Given the changing disturbance regimes and climate, there is a critical need to take decisive and extensive actions in the next 1-2 decades to conserve Sierra Nevada forests. This synthesis provides a summary of how climate change and fire are impacting our Sierra Nevada Mixed Conifer forests and how active management can help mitigate some of these impacts.
Read MoreInsights from wildfire backburns for conducting hot prescribed burns in ponderosa pine plantations: Research Brief
/
In this study, researchers examined the effects of backburning operations in a heavily stocked ponderosa pine plantation during the 2012 Mill Fire.
Read MoreTreatments and Planting Location Affect Post-Burn Restoration: Research Brief
/
On a burned site in the northeastern Mojave Desert that is conservation-priority habitat for federally listed desert tortoises, a field experiment was conducted to test different treatments for outplanting greenhouse-propagated seedlings of the native perennial brittlebush (Encelia virginensis).
Read MorePost-Fire Recovery Four Decades after Desert Wildfires: Research Brief
/
Authors studied the recovery of plant communities, soil properties, soil biocrusts and grass as plant fuel on 31 wildfires in the eastern Mojave Desert that had between 1980 and 2007.
Read MoreReducing Fuel while Protecting Soil Biocrusts: Research Brief
/
Non-native annual grasses, such as red brome (Bromus rubens), have increased the amount and continuity of fine fuels in drylands of the southwestern U.S. Where herbicide is not allowed or may have undesirable non-target effects, one of the alternative treatments that has been proposed and used in more mesic habitats is carbon addition.
Read MoreStand Structure in the Sierra de San Pedro Mártir: Research Synthesis
/
The SSPM can help guide management decisions in mixed conifer/ yellow pine forests of the western US/ California that wish to return forests to historical (pre-European) conditions or prepare them for a changing climate and an uncertain future.
Read MoreFire severity impacts on plant species richness: Research Brief
/
Plants often have characteristics that make them well suited to the common type, frequency, and/or severity of disturbance in ecosystems where they occur. Plant species richness was found to be affected by historical fire regime and severity in coniferous forests of the Western US.
Read MoreImpacts of Repeated Prescribed Burns on Fuel and Forest Conditions in the Sierra Nevada: Research Brief
/
This study focused on better understanding the role of stand characteristics and burn entry number in fuel consumption.
Read MoreFire-caused Vegetation Type Conversion in California: A Workshop Summary
/
In December 2019, partners from the U.S. Geological Survey, University of Arizona, and EcoAdapt hosted a two-day workshop in Sacramento, California, to discuss observations of and management options for fire-caused vegetation type conversion (VTC). A summary of this workshop and a call for resources (through 2021) are included in this summary.
Read MoreThe Mixed Impressions of Hikers in Post-fire Chaparral: Research Brief
/
Two years after the 2015 Wragg Fire burned the Reserve, a restored public trail was reopened for use. The authors used surveys to determine public perceptions of fire in this chaparral ecosystem.
Read MoreUse Cross-scale Metrics to Help Manage for Resilience: Research Brief
/
In our changing world, community change may be a resilience response indicating a process of adaptation rather than of failure. Falk and colleagues (2019) argue that resilience goals should be updated to better apply to 21st century ecosystems.
Read MoreHow to Manage for Resilience During Climate Change? Research Brief
/
This research suggests that collaborative learning among stakeholders (aka knowledge coproduction) would be a good way to develop context specific resiliency metrics and goals, making the term more useful by operationalizing it.
Read MoreHow to Reduce House Exposure & Sensitivity to California Wildfire: Research Brief
/
Although the causes of the fires vary by ecoregion and require location- and driver-specific management tools, there are effective ways to reduce both structure exposure and structure sensitivity to fire across all of California.
