PSW research scientist Dr. Constance "Connie" Millar has been elected as a fellow of the American Association for the Advancement of Science.

A recent USDA Blog post highlights efforts by Pacific Southwest Research Station's Institute of Pacific Islands Forestry to study, restore and preserve mangrove forests.

A recent Pacific Southwest Research Station (PSW) study addresses the benefits of a high variability thinning method to mitigate the risks overstocked forests.

Pacific Southwest Research Station's 2019 Science Spotlight is now available on our publications page and highlights some of our station's latest research, discoveries and tools.

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

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.

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.

Urban tree monitoring: a field guide

Urban tree monitoring: a resource guide

Urban Tree Monitoring: A Resource Guide

(GTR-PSW-266)

Guidelines in this report were developed and refined over many years to address the need for standardized urban tree monitoring protocols and provides in-depth guidance for urban forest managers.

Innovative strategies to reduce the costs of effective wildlife overpasses

(GTR-PSW-267)

Wildlife crossing structures have been one of the most effective means of reducing animal-vehicle collisions. Yet widespread implementation has been hindered by perceived and actual expense.
