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.

Since 2010, an estimated 40 million trees have died in California. Visit the California Tree Mortality website to learn about the Forest Service's response and National Forest visitor safety.

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.

Citizen scientists monitor a deadly fungus threatening amphibian communities in northern coastal California, USA

Citizen science projects increasingly are making important contributions to conservation science. While many projects focus on participation by adults, the inclusion of children in citizen science can be beneficial because children are enthusiastic and curious observers.

Youth with the Bilingual McKinleyville Ecoclub are helping scientists from Pacific Southwest Research Station monitor a deadly fungus threatening amphibian communities along California’s north coast. Kids, age 4 to 16, were trained to safely catch frogs and salamanders, and then administer a skin swab to test for Batrachochytrium dendrobatidis, a fungus linked to the decline or extinction of more than 200 amphibian species worldwide.

Of the 155 amphibians collected during the two-year study period, 26 tested positive for the fungus. The study results are published in the Journal of Wildlife Diseases and is available on Treesearch.

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.
