Predicting Douglas-Fir’s Response to a Warming Climate

U.S. Forest Service Pacific Northwest Research Station Science Findings November 2015 Douglas-fir is an iconic tree in the Pacific Northwest. Although individual trees may appear to be identical, genetic differences within each tree have resulted from adaptation to the local environment. These genetic differences over time have resulted in differences among populations that are important […]

Using forest knowledge: how silviculture can benefit from ecological knowledge systems about beargrass harvesting sites

U.S. Pacific Northwest Research Station Gen. Tech. Rep. PNW-GTR-912 2015 Sustaining the health, diversity, and productivity of national forests and grasslands is the mission of the U.S. Department of Agriculture (USDA) Forest Service. Yet managing these lands is challenging because people hold different expectations for them. Public uses can include: • Recreation (scenery, trails, bicycle […]

Fingerprints of a forest fungus: Swiss needle cast, carbon isotopes, carbohydrates, and growth in Douglas-fir

U.S. Forest Service Pacific Northwest Research Station Science Findings November 2014 Swiss needle cast is caused by a fungus native to the Pacific Northwest. Its host is Douglas-fir, an iconic evergreen tree in the region. The fungus does not kill its host, but it adversely affects the tree’s growth. Scientists with the Pacific Northwest Research […]

Assisted Migration: Growing Forests Adapted to the Future

The Forestry Source January 2014 Of the management strategies available to create resilient, productive forests in a changing climate, assisted migration is one strategy that is prompting much discussion within the forestry community. Assisted migration is viewed as a proactive strategy because many tree species do not have the ability to adapt or migrate naturally […]

The Challenges of Active Forest Management in an Ecological Reserve

The Forestry Source September 2013 When your Habitat Conservation Plan (HCP) requires an accelerated development of a second-growth forest into a late-successional forest, that’s a tall order to carry out especially when there isn’t an established silvilculture prescription to create such a forest structure. And when your prescriptions call for thinning in a landscape that […]

The Many Faces of the University of Washington’s Pack Forest

TimberWest May/June 2013 When you visit the Charles L. Pack Experimental Forest, you are not just taking a walk through a forest, you’re seeing sustainability in action. Through spacing trials, selection thinning, fertilizer treatments, and ecosystem-value services research, the Center of Sustainable Forestry demonstrates that sustainability and active forest management are not mutually exclusive.
