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.

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.

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.

How to Reduce House Exposure & Sensitivity to California Wildfire: Research Brief

How 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.

Easing Prescribed Fire Liability Laws Increases its Use as a Management Tool: Research Brief

A comparison study of different liability lows shows how gross negligence coupled with some key additional regulations would likely result in prescribed fire being more available to managers while also providing safety assurance to the public.
