What's new
This microscopic view of a moss cell represents the colorful and often hidden world of discovery unearthed by the Forest Service, the largest forestry research organization in the world.

The Forest Service is recognized the world over as a premier producer of applied science. Follow some of the highlights on the new Forest Service Research & Development Facebook page.

Large trees line a neighborhood street.

A new report from Pacific Southwest Research Station estimates trees lining Californian streets and boulevards provide benefits to municipalities and residents worth $1 billion.

Our researchers are working with the University of Hawaii and other partners to spread awareness on Rapid Ohia Death. Visit the Hawaii Forestry Extension website to learn about the disease.

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.

Scientific research to improve the environment in the Lake Tahoe Basin
Cover photo of the Tahoe Science Consortium Science Synthesis Report.
The Tahoe Science Consortium Science Synthesis Report is now online. Read the executive summary or view the full report.

The Tahoe Science Program was created through the Southern Nevada Public Lands Management Act (SNPLMA) to conduct science to inform efforts to restore Lake Tahoe and its watershed, as authorized in the Lake Tahoe Restoration Act. Pacific Southwest Research Station assumed responsibility in 2006 for sponsoring science projects using SNPLMA funds and worked with the Tahoe Science Consortium to identify research priorities and solicit proposals.

The program is a partnership between federal and state agencies, local jurisdictions, and the science community to achieve science-based decision-making and restoration of the Lake Tahoe Basin through environmental monitoring, applied research, and data application.

The Tahoe Science Consortium Science Synthesis Report was recently released and provides an overview of the key findings from the research projects supported by the SNPLMA Science Program and illustrates their relevance to management actions in the Lake Tahoe Basin.

Restoring California black oak ecosystems to promote tribal values and wildlife

This report synthesizes information to help promote the distinctive ecological and cultural benefits provided by California black oak. Production of abundant, high-quality acorns desired by Native Americans in California, as well as other valued services, requires the presence of mature, broad-crowned trees with low fuel levels and low pest levels.

Evaluation of standard methods for collecting and processing fuel moisture samples

A variety of techniques for collecting and processing samples to determine moisture content of wildland fuels in support of fire management activities were evaluated. The effects of using a chainsaw or handsaw to collect samples, containers for storing and transporting samples, and quick-response ovens for estimating moisture content were evaluated.

Water Temperature, Dissolved Oxygen, Flow, and Shade Measurements in the Three Stream Sections of the Golden Trout Wilderness

To determine the current range of water temperatures in the streams inhabited by California golden trout, Oncorhynchus mykiss aguabonita, water temperature recording probes were deployed and monitored from 2008 through 2013 in three meadows in the Golden Trout Wilderness.
