• A Conservation Assessment and Strategy for the Humboldt Marten
• Proceedings of the Fifth International Symposium on Fire
• The Fourth National Climate Change Assessment is online
• Researchers piece together disparate records as disease closes in on western bats
• Smoke from wildfires has cooling effect on water temperatures

This assessment and strategy was developed in response to the decline of the Humboldt marten throughout most of its historical range in California and Oregon.

The Proceedings of the Fifth International Symposium on Fire Economics, Planning, and Policy: Ecosystem Services and Wildfires is now available in an English version and versión en Español.

The Fourth National Climate Change Assessment was recently released. PSW joined other USFS researchers to co-author the chapter highlighting impacts and risks to our Nation’s forests.

A concerted effort by the scientific community has produced one of the largest and most complete datasets of recorded hibernacula in the western United States.

Smoke generated by wildfires can cool river and stream water temperatures, according to a new study in California’s Klamath River Basin.

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.

How healthy is your ahupua'a (watershed)?

Hawaii Conservation Alliance's Community Watershed Snapshot Guidebook is a first step to understanding, analyzing and addressing humanity's relationship with its environment as part of the solution to taking care of Hawai'i. This is a participatory and collaborative process to answer the burning question, "How healthy is your ahupua'a (watershed)?"

Completing the snapshots gave our communities the opportunity to produce game plans aimed at improving ridge-to-reef ecosystems by addressing some of the priority issues that currently exist. Through this snapshot process and cooperatively developed communications tools (poster, fact sheet with infographics and PowerPoint presentation), we have a greater ability to proceed on watershed scale resource management as a unified community.

Using species distribution models with climate change scenarios to aid ecological restoration decisionmaking for southern California shrublands

(RP-PSW-270)

This paper features species distribution models for incorporating climate change scenarios into restoration decisions for southern California scrub and shrubland habitats.

Passive monitoring techniques for evaluating atmospheric ozone and nitrogen exposure and deposition to California ecosystems

(GTR-PSW-257)

In this report, several alternative approaches for estimating N deposition are also considered as a guide for selecting appropriate techniques in ecosystem-effects studies in California and elsewhere.

Proceedings of the Coast Redwood Science Symposium—2016: past successes and future direction. Proceedings of a workshop

(GTR-PSW-258)

With its limited range and high value, the coast redwood forest is a microcosm of many of the emerging science and management issues facing today’s forested landscapes.
