• Science shows that demographics and funding impact wildfire resilience
• Beneath the Surface: The Hydrology of Hidden Forests Systems
• Natural range of variation for yellow pine and mixed-conifer forests
• Past fires may hold key to reducing severity of future wildfires in western US
• Federal/Tribal partnerships for wildland fire research and management

Recent studies have found that demographic factors play a big role in how homeowners perceive and respond to wildfire risk.

To understand the relationship between drought and water use in trees, PSW hydrologists are looking at underlying bedrock in the Kings River Experimental Watershed.

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

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.

The 2022 Pacific Southwest Research Station Director's Honor Awards recognize the outstanding contributions and excellence that employees added to the community and research & development throughout the year. The significant, invaluable contributes to the USDA Forest Service's Mission and goals are honored in the following categories: Community Enhancement and Diversity Award, Distinguished Science, Innovation and Service in Business Operations, Innovation and Service in Research, Improving the Station Workplace, and Science Delivery.

Richard Barhydt, the station director for Pacific Southwest Research Station (PSW), offers his appreciation to all who strive for the extraordinary in service of PSW, the Forest Service, and the public every year.

Forest management handbook for small-parcel landowners in the Sierra Nevada and southern Cascade Range

(GTR-INF-001)

A significant portion of Sierra Nevada and southern Cascades forests are owned and managed as small parcels (10 to 100 acres) by nonindustrial private landowners. This handbook is for such landowners to help them develop a sound forest management strategy for their property.

Science to Enhance Ecosystem Stewardship

Pacific Southwest Research Station Charter 2022-2031

The Pacific Southwest Research Station charter highlights how partners like local, State, Tribal, and Federal agencies and policymakers, universities, communities, indigenous groups, private industry, and non-profit entities help shape PSW both formally and informally.

Measuring individual ozone exposure in Los Angeles urban parks

(GTR-PSW-274)

Exposure to ozone pollution has serious health risks. Damage to lungs and cardiovascular health are of particular concern for vulnerable populations, including children, the elderly, and individuals from "disadvantaged" communities whose health may already be compromised.
