Forest mid-story interactions with prescribed fire behavior: Research Brief

Forest mid-story interactions with prescribed fire behavior: Research Brief

The study used models to predict fire behavior differences according to two primary factors: mid-story density (i.e. the ladder fuel layer) and live fuel moisture. This is relevant for prescribed burns because both of these factors can be modified when conducting burns.

Drought and bark beetle induced tree mortality elevates wildfire severity of California’s Sierra Nevada forests: Research Brief

 Drought and bark beetle induced tree mortality elevates wildfire severity of California’s Sierra Nevada forests: Research Brief

This article uses field data from two wildfires (the 2015 Rough Fire and 2016 Cedar Fire) that burned in areas of recent severe tree mortality to examine whether and under what conditions the pre-fire tree mortality affected wildfire severity.

Post-fire Restoration Framework for California’s National Forests: Research Brief

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.

Longer-term impacts of fuels reduction treatments in the Lake Tahoe Basin: Research Brief

Longer-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.

Linking diverse terminology to vegetation type-conversion, a complex emergent property: Research Synthesis

Linking 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.

Forest recovery following extreme drought in California: Research Brief

Forest 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.

Interactions Between Fire and Climate in the California Sierra Nevada: Research Synthesis

Interactions 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.

Treatments and Planting Location Affect Post-Burn Restoration: Research Brief

Treatments 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).

Reducing Fuel while Protecting Soil Biocrusts: Research Brief

Reducing 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.

Stand Structure in the Sierra de San Pedro Mártir: Research Synthesis

Stand 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.

Fire severity impacts on plant species richness: Research Brief

Fire 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.

Fire-caused Vegetation Type Conversion in California: A Workshop Summary

Fire-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.

The 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.

Use Cross-scale Metrics to Help Manage for Resilience: Research Brief

Use 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.
