What's new
A high variability thin unit in the summer of 2020 – eight years after thinning and six years after prescribed burning.

What does a 'resilient' forest look like in California's Sierra Nevada? A lot fewer trees than we're used to, according to a new study of frequent-fire forests.

A mixed-conifer stand that has been thinned and then burned within the last 5 to 10 years, McCloud Ranger District, Shasta-Trinity National Forest

This assessment examines the range of conditions that exist among the yellow pine and mixed-conifer forests of northwestern California and southwestern Oregon.

This report (GTR-274) describes three successive studies that led to the development of techniques for directly monitoring human exposure to ozone.

The McCash Fire burns into areas that recently burned (brown areas) and areas that had burned in previous wildfires in the Klamath Mountains.

A recent Pacific Southwest Research Station study examined the role of previous fires in predicting and reducing the severity of future wildfires in the western United States.

This recent journal article discusses various approaches in working with American Indians through research and management partnerships in the fields of wildland fire, forestry, and fuels.

Science that makes a difference.

The Pacific Southwest Research Station is a world leader in natural resources research through our scientific excellence and responsiveness to the needs of current and future generations.

We represent the research and development branch of the USDA Forest Service in the states of California and Hawaii and the U.S. affiliated Pacific Islands. Our mission is to develop and communicate science needed to sustain forest ecosystems and their benefits to society.

Forest Management Handbook For Small-Parcel Landowners

The handbook describes how to create a forest management plan for small parcel landowners.

Family-owned forest lands make up about 7 million acres, around 20 percent, of California's forests. Most of these acres are owned and managed as small parcels (10 to 100 acres) by nonindustrial private landowners. The USDA Pacific Southwest Research Station, in partnership with CAL FIRE and the USDA California Climate Hub, created a handbook to provide concise and thorough information to help these landowners develop a sound forest management strategy for their property

The Forest Management Handbook for Small-Parcel Landowners in the Sierra Nevada and southern Cascade Range features information gathered from a large body of current scientific literature that provides relevant technical information for landowners. The step-by-step guide will help landowners gather the information needed to build a California cooperative forest management plan, including determining what, if any, management actions need to be done, and how to obtain technical and financial support.

Innovative strategies to reduce the costs of effective wildlife overpasses
(GTR-PSW-267)

Wildlife crossing structures have been one of the most effective means of reducing animal-vehicle collisions. Yet widespread implementation has been hindered by perceived and actual expense.

Natural range of variation for red fir and subalpine forests in northwestern California and southwestern Oregon
(GTR-PSW-269)

Future climate and wildfire projections indicate an extension of the fire season and an increase in fire size and severity in these forest types.

Postfire restoration framework for national forests in California
(GTR-PSW-270)

This report presents a framework to guide the development of postfire restoration on national forests in California. We discuss the application of this approach to California’s forest, chaparral, and sagebrush-steppe ecosystems.
