Seven Principles for Restoring Fire-Prone Inland Pacific Forests


Hessburg is lead author of a recent paper that represents a unified vision of landscape restoration, from a diverse group of thinkers. Scientists from leading universities, GOs and NGOs – including the Aldo Leopold Wilderness Research Institute, The Nature Conservancy, and The Wilderness Society – contributed to the study.

The top photo was taken in 1934, and large patches of recently burned areas are clearly visible. Patches of young forests are also apparent. The bottom photo is from 2010, after decades of fire suppression. The area that is forested has expanded considerably, as has the density of forests, William Osborne Collection, NARA Seattle (1934) / John Marshall Photography (2010).


Genetics and geography: DNA markers identify origin of white oak wood


At first glance, white oak trees, DNA, and Siberian tigers may seem to have little in common. But with financial support from the U.S. State Department and U.S. Agency for International Development, the Forest Service’s Pacific Northwest Research Station and Germany’s Thünen Institute of Forest Genetics are linking all three through research that offers a new approach for sleuthing the source of wood products and combating illegal logging.

PNW Research Station scientists are exploring the use of a portable DNA sequencer, shown here, for DNA-based identification of plants and plant pathogens. Driven by a laptop, this sequencer generated a MinION run of Oregon White Oak DNA. Photo courtesy of Rich Cronn, USFS.

Native Pacific Trout: Swimming into the Future?


Pacific trout are survivors. Cutthroat trout, golden trout, Gila trout, Apache trout, and others in the Oncorhynchus genus have lived through glaciations, volcanoes, enormous floods, and major shifts in the tectonic plates of Earth – shifts that have created our current mountain ranges and stream beds.
