Increases in mortality among Douglas-fir in the Klamath Mountains are the result of multiple factors that have the iconic tree in a “decline spiral” in parts of the region, a new study by the Oregon State University College of Forestry and OSU Extension Service indicates.

Oregon State University research into the ability of a wildfire to improve the health of a forest uncovered a Goldilocks effect – unless a blaze falls in a narrow severity range, neither too hot nor too cold, it isn’t very good at helping forest landscapes return to their historical, more fire-to

The findings are important for understanding how the global carbon cycle might change as the climate grows more warm and dry, said Oregon State University’s Jeff Hatten, co-author of the study published in the Proceedings of the National Academy of Sciences.

A collaboration led by an Oregon State University College of Forestry researcher has used very-high-resolution satellite imagery to develop a machine learning model that aims to improve climate scientists’ ability to estimate aboveground carbon stocks in the Amazon.

If conifer tree planting is on your late winter or early spring to-do list, there are some things you can do to improve your success.

An international collaboration led by Oregon State University scientists has identified 27 global warming accelerators known as amplifying feedback loops, including some that the researchers say may not be fully accounted for in climate models.

Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, Oregon State University researchers say.

OSU and state officials, with consultation from a stakeholder group, are negotiating terms of a potential agreement for the university to provide research management of the 82,000-acre forest, which is situated in the Coast Range near Reedsport.

A long-term Pacific Northwest study of landslides, clear-cutting timber and building roads shows that a forest’s management history has a greater impact on how often landslides occur and how severe they are compared to how much water is coursing through a watershed.

Douglas-fir trees will likely experience more stress from drier air as the climate changes than they will from less rain, computer modeling by Oregon State University scientists shows.
