As part of the Collaborative Forest Landscape Restoration Program (CFLRP), USDA Forest Service Region 6 is implementing silviculture and prescribed-fire treatments to restore forests to historical structure and composition in the northern Blue Mountains of the Pacific Northwest on the Wallowa-Whitman and Umatilla National Forests. In 2021, we began a pilot monitoring effort to evaluate the efficacy of using passive acoustic recording units (ARUs) to monitor white-headed woodpecker (Picoides albolarvatus, hereafter WHWO) habitat use, and we demonstrated that ARUs are more efficient and more eff...

Western redcedar is an iconic tree species in the Pacific Northwest, with deep cultural, economic, and ecological ties in the region. However, recent elevated rates of WRC dieback have raised concern about the future of this species under changing climate conditions. This fact sheet summarizes recent work assessing the dieback period from 2015-2018 in the Pacific Northwest and highlights management considerations.

The Institute continues to serve as a collaboration hub for national and international initiatives. Our Research and Development Unit remains an influential figure on tropical forestry research; the State, Private and Tribal Forestry Unit made technical and financial assistance accessible to communities across the U.S. Caribbean, and International Cooperation maintains close relationships with international partners for the conservation of biodiversity in tropical ecosystems. As is evident in the accomplishments detailed in this report, IITF has shown remarkable dedication and a deep sense of ...

This factsheet summarizes the recent report, Air pollution effects on forests: A guide to species ecology, ecosystem services, and responses to nitrogen and sulfur deposition

This is a list of fungi species that have been observed or "DNA-detected" within the Priest River Experimental Forest. The list was compiled in 2023 and 2024 using historical records, studies, and reports.

The MC2 dynamic global vegetation model (DGVM) simulates ecosystem processes and their response to climate change. It has been used in a wide range of climate model and assessment applications, from fire severity to the economics of timber harvest. This fact sheet offers a brief summary of the model itself along with a sample of the range of work MC2 has been used in.

Outbreaks of defoliator insects (insects that feed on the needles and leaves of plants) play a major role in shaping Pacific coastal temperate rainforests. This fact sheet outlines how researchers are using historical data and an ensemble machine learning model to better understand the factors influencing outbreaks of two major defoliator species in the Pacific Northwest and Southeast Alaska, and how climate change may be changing those factors.
