U.S. Forest Service Chief Victoria Christiansen recently announced Richard Barhydt as the new station director for the Pacific Southwest Research Station.

Valley oak seedlings were planted at the PSW-Institute of Forest Genetics as well as the USFS Chico Seed Orchard. U.S. Forest Service by Jessica Wright.

By identifying genotypes with faster growth rates under warmer temperatures, research presents an approach to mitigate negative consequences of rising temperatures for valley oak.

Sisters Lillian Rentz and Janet Morehead of the Karuk Tribe examine harvest California hazel stems from a prescribed burn area. U.S. Forest Service by Frank K. Lake.

A new study in collaboration with the Yurok and Karuk tribes found that incorporating traditional techniques into fire suppression practices can also help revitalize American Indian communities.

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.

Science Focus: Promote Shared Stewardship

Part 1 of a 5-part animated series offers a broad overview to help viewers begin to undertake urban tree monitoring projects.
Monitoring urban trees

Trees that line city streets and grow in front yards provide beauty, color, shade and a multitude of other benefits to urban areas, but their health and longevity depend heavily on the urban foresters, citizen scientists and volunteers who monitor and take care of them.

Researchers from Pacific Southwest Research Station and Northern Research Station partnered to author two publications and have produced companion videos that serve as guides for monitoring urban trees and helping ensure viability of urban forests over the long run.
