Learn how woodpeckers contribute to the recovery of burned forests and how land managers can support a diverse of woodpecker population. See the story on the USDA Blog.

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 eighth-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.

Caspar Creek Watershed:
More than 50 years of research focusing on clean water

Healthy forests are vital for maintaining clean and abundant supplies of water. One of our research station’s premiere long-term studies focuses on the effects of forest practices on stream water quality. For more than 50 years, experiments within the Caspar Creek Experimental Watershed have helped to provide information useful for developing forest management activities that minimize impacts to water quality. Results of our research have been used to develop strategies for controlling hydrologic changes due to logging in coastal redwood forests and to refine forest practices on watershed-related topics.

Salli Dymond: Studying the role of forest management in balancing forests and water in a changing climate

While maintaining and sustaining clean water is important, it’s also important to ensure an abundance of water especially in climates facing severe drought. As drought-related stresses impact forests, one of the challenges the Forest Service is faced with is the managing forests for water supply. Research has shown that reducing the number of trees in a watershed can increase water yield from that area, but there are many questions that remain to be answered. Salli Dymond, a postdoctoral research hydrologist with Pacific Southwest Research Station, is exploring some of those questions with a research project that builds on more than 50 years of research at the Caspar Creek Watershed.
