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 primary work occurs in California (the most populous state with the fifth largest economy in the world) and Hawaii (a strategic location in the Pacific Rim economies and tourism).

Our mission is to develop and communicate science needed to sustain forest ecosystems and their benefits to society.

News Release: Long-term changes in dead wood reveal new forest dynamics
Dead wood on the ground in the foreground with fire burning through the downed material in the background.Healthy forest ecosystems need dead wood to provide important habitat for birds and mammals, but there can be too much of a good thing when dead wood fuels severe wildfires. A scientist with the Pacific Southwest Research Station compared historic and recent data from a forest in California’s central Sierra Nevada region to determine how logging and fire exclusion have changed the amounts and sizes of dead wood over time.

Endangered ae‘o chicks. U.S. Forest Service photo by Rich MacKenzie Blog: When exotic fish are away, Hawaiian waterbirds will stay
In the Pacific Islands, coastal wetlands provide habitat for many unique species and support communities who rely on these special places for food and other essentials. But a threat lurks beneath the water's surface: non-native fish. Researchers with the Institute of Pacific Islands Forestry are studying the threats posed by exotic fish species and working with partners to battle the gilled invaders.

Video: Science Perspectives - Air quality in Devils Postpile National Monument
Air pollution from cities moves through California’s Central Valley and the San Joaquin River drainage and affects air quality at Devils Postpile National Monument. Senior scientist Andrzej Bytnerowicz discusses the phenomenon and air quality monitoring research conducted in partnership with the National Park Service in a new video.

Urban Forestry

The urban forestry initiative in Los AngelesMillion Trees Los Angeles: carbon sink or source?
Are urban Tree Planting Initiatives (TPIs) likely to be effective means for reaching local carbon dioxide reduction targets? Research forester Greg McPherson and partners determined that a large-scale TPI, Million Trees Los Angeles (now called City Plants), is achieving success in terms of survival, growth and performance.

New research evaluating tree species for climate adaptation
Climate change poses challenges for California, where an already parched region is expected to get hotter and, in its southern half, significantly drier. Research forester Greg McPherson and partners are identifying the resilience of different tree species to future climate exposure and threats from pests and disease in the Central Valley.

California’s climate change policies and programs
Station research and partner California ReLeaf’s advocacy efforts have resulted in $17.8 million in cap-and-trade auction revenues for California Department of Forestry and Fire Protection’s (CAL FIRE) Urban and Community Forestry Program in 2014-15, the largest one-year single-state allocation for urban forestry. Research forester Greg McPherson and partners published an article that traces the history of this effort.
