Northwest forests are becoming denser and more vulnerable to fire

Those are among the results of a comprehensive analysis of forest structure and biodiversity based on satellite imagery and on-the-ground field work in the eastern Cascades of Washington, Oregon and Northern California from 1985 to 2010. Matthew Reilly, a former Ph.D. student in the College of Forestry at Oregon State University led the study, which was published in the journal Ecological Applications.
