Forest Service Conducts Fuel Reduction Work in Lake Tahoe Basin

Forest Service Conducts Fuel Reduction Work in Lake Tahoe Basin
The USDA Forest Service Lake Tahoe Basin Management Unit continues cut-to-length mechanical fuels reduction (forest thinning) operations on approximately 275 acres around the Lake Tahoe Basin. This fuels reduction work is part of the NV Energy Resilience Corridors Project that aims to reduce the risk of severe wildfire and create healthier and more resilient forests.

Reclamation Continues Wildfire Prevention in Auburn Project Lands with Fuels Reduction Project
The Auburn area Five-Year Fuels Reduction Project work is on schedule and the Bureau of Reclamation’s contractor, Wildfire Services Group, Inc., has completed several segments of shaded fuel break construction and maintenance work on Auburn Project Lands within the Auburn State Recreation Area in Placer and El Dorado counties.
USFS Uses Machine Learning to Promote Meadow Restoration

USFS Uses Machine Learning to Promote Meadow Restoration
Pacific Southwest Research Station U.S. Forest Service ecologists have developed new machine learning algorithms to identify potential locations of lost meadows where forests now encroach. Meadows in California’s Sierra Nevada mountains historically covered nearly three times the area they do today. New maps of lost meadows provide a large-scale perspective to help us think differently about the historical importance of meadows and the positive impact their restoration could have on streamflow and wildfire management.
Project Implementation in High-Risk Regions – Santa Monica Mountains
Project Implementation in High-Risk Regions – Santa Monica Mountains
Department: Santa Monica Mountains Conservancy
Program Description: The Santa Monica Mountains Conservancy prioritized wildfire resilience projects that proactively reduce the risk of wildfire, strengthen wildfire resilience, increase carbon sequestration, rally against the effects of climate change, and dedicate more resources to local community infrastructure.
Program Impact: In 2022, the Conservancy coordinated with partner agencies, non-profit organizations, local tribes, and other stakeholders to kickstart projects that performed one or more of the following types of wildfire resilience activities.
Wildfire resilience activities included:
- Removing dry, hazardous, or non-native vegetation that poses ignition risk and habitat restoration
- Increasing the efficacy of wildfire response through emergency operations equipment and workforce development
- Ignition monitoring program
- Fire hardening at-risk structures
Conservancy wildfire resilience efforts, initiated in 2021 and sustained throughout 2022, addressed major wildfire hazards in the Santa Monica Recreation Area. State funding supported projects that mitigate hazards posed by fuel-vegetation, human actions, and at-risk structures. Investment in workforce development and capacity building in climate, fire resilience, and habitat restoration further enhanced wildfire prevention and emergency response operations. Ongoing project efforts will continue to reduce wildfire risk throughout the 2023 fire season and following years.

Resilience in Action: Fuel reduction along the ignition-prone highway 101 corridor continued in 2022, and as of January 2023, approximately 2,000 fire-resistant oaks have been planted at five key sites. In the coming years, fire-resistant oak habitat will replace the existent grassy fuel vegetation and serve as a natural fire buffer around the freeway. Funding for workforce development supported an expanded crew of seasonal firefighters in the Fire Division of the Mountains Recreation and Conservation Authority who received basic and advanced fire training classes, drills, and fuel vegetation removal.

Southern California Regional Resource Kit
Southern CaliforniaRegional Resource Kit
The resource kit contains a core set of data layers that reflect management-relevant metrics for the Southern California region. These data and metrics have been vetted by federal, state, and academic scientists. In total, the Southern California Regional Resource Kit contains nearly 70 metrics selected to be informative, meaningful, and actionable for management.
Additional Details
Most data layers are available at 30 m resolution, but some are available at the resolution of the original data set (e.g. the California gnatcatcher suitable habitat data layer was developed at 150 m pixel resolution).
Each data layer is available for downloading and can also be viewed as an image file. .
View & Download Data
Framework For Resilience
The metrics are organized by ten desired outcomes, termed “Pillars of Resilience” from the Framework for Resilience. The metrics describe the characteristics of one of the pillars in quantitative or, in a few cases, qualitative terms.
Additional Details
All data layers are available at 300 m resolution (i.e. pixels are 300 meter on a side) and some are also available at 30 m resolution. The same data layers are also available rescaled to a value of -1 to +1 to put all data layers in the same units for additional analytical work among metrics and pillars.
Metric Dictionary
A metric dictionary for the Southern California Regional Resource Kit provides details on the nature of each metric. Each metric has been defined to help end-users of the data (and for use with any decision support tools) to understand:
- The definition of a given metric
- The expected use(s) of the metric
- The resolution of the developed data
- The data sources used to derive the metric
- The method of metric derivation
- The root file names
References have been included to help the reader understand potential methods for deriving metrics.

USFS Awards CALREC Vision Partnership of the Year

USFS Awards CALREC Vision Partnership of the Year
December 14, 2022 – At the Regional Foresters Awards Ceremony in Sacramento, CA, the Leadership Team of the Sustainable Recreation/CALREC Vision Key Working Group (SRCRV) was awarded a Regional Forester’s Honor Award for Partnership of the Year from the U.S. Forest Service Pacific Southwest Region. The award recognizes the Leadership Team’s efforts to develop California’s Joint Strategy for Sustainable Outdoor Recreation and Wildfire Resilience for California’s Wildfire & Forest Resilience Task Force. The Joint Strategy satisfies Key Actions 3.13 and 3.14 of the California Wildfire and Forest Resilience Action Plan. The California Wildfire and Forest Resilience Task Force will publish the Joint Strategy in early 2023.
Accepting the award with Jennifer Eberlein (second from left), from left to right are Bill Keane, Climate Equity Solutions, Inc.; John Wentworth, Mammoth Lakes Trails and Public Access Foundation; Austin McInerny, Consensus and Collaboration Program, College of Continuing Education, Sacramento State University; and Nancy Parachini, USFS Deputy Director of Public Services.

Timing of Fire Study
Wildland firefighters from the Stanislaus National Forest and researchers from Pacific Southwest Research Station conducted a 21-acre prescribed burn on the Tuolumne Experimental Forest on October 29-30, 2022. The prescribed burn was a part of a Timing of Fire Study allowing researchers to compare how seasonal conditions affect the outcomes of prescribed fire. This video shows how we study the effects of prescribed fire and what we can learn.
