“There’s been concern for some time over pollinator declines,” said Jim Rivers, lead scientist and forest ecologist in the College of Forestry. “Some people have gone so far as to call it a pollinator crisis.

“This paper is the first to look at the effects of climate change on stream metabolism at the continental scale using field observations,” said Alba Argerich, co-author who monitored McRae Creek and Lookout Creek in the H. J. Andrews Experimental Forest east of Eugene, Oregon.

Oregon State University Extension Service hosted the seminar.

Scott Leavengood says juniper has fantastic durability – meaning its well suited for outdoor use. The wood also has high compression strength, something sought out for construction products like sill plates (the piece of lumber that joins a house’s foundation with its frame).

“Ideally we’d have markets for the small trees and biomass that result from these treatments,” said Nicole Strong, assistant professor at Oregon State University’s College of Forestry.

“It’s almost like an ethical distraction, calling it by some other name,” said co-author Michael Paul Nelson, a professor and the Ruth H. Spaniol Chair of Renewable Resources at OSU. “We have these metaphors that we hide behind.

With funding from the state Legislature, forest ecologists and ornithologists at Oregon State are conducting a long-term, large-scale study to determine what the marbled murrelet needs to survive.

“We leveraged a fire severity metric that integrates fire intensity and tree susceptibility. We demonstrated how industrial forest management increases these aspects of fire risk,” said Harold Zald, lead author and a former post-doctoral scientist at Oregon State.

The renewable materials program provides four tracks from which to choose: science and engineering; marketing and management; art and design; and advanced wood manufacturing.

But something about substantial animals makes them more vulnerable to population collapse, said William Ripple, director of the Global Trophic Cascades Program at Oregon State University. For starters, there are usually fewer of the big animals, at least compared with the little guys.
