Extension offering local classes for small-woodlot owners

More than a year after uprooting its forestry program in Lane County because of a lack of funding, the state Extension Service has figured out how to resume offering some help to small-woodlot owners and others who want to learn more about growing and harvesting trees.  The service, run by Oregon State University, will bring OSU forestry experts assigned to other counties to Lane County, to hold a series of one-day classes that will cost $25 per attendee.

How A Tiny Fungus Is Starving Coastal Douglas Fir Trees

In 2008, scientist and CoF assistant professor Bryan Black took core samples the diameter of a pencil from a forest near the north Oregon coast. Most of the trees were hemlocks and Douglas fir that had been undisturbed for about 90 years.  The hemlocks were growing normally. But Black was shocked at what he saw in the Douglas fir samples.  “In 1984, these Douglas fir all but shut down,” Black says. “In fact, their growth was so slow that it wasn’t even forming wood around the whole circumference of the tree.”

Forest Health in Oregon: State of the State 2012

Forest Health in Oregon: State of the State 2012 is a one-day conference and continuing education event designed to synthesize the current forest health conditions of Oregon forests by focusing on mortality agents and other factors that negatively impact forest trees.  It will be held on March 1 at the LaSells Stewart Center, OSU.

John Mann Selected as New Director of College Forests

Effective January 1, 2012, John Mann became the College of Forestry’s new Director of College Forests.

The College Forests at Oregon State University include 14,500 acres of forestland in a statewide network of research, teaching, and outreach forests, with the 11,500-acre McDonald and Dunn Forests at the core of this network.

"John brings a wealth of experience and diverse background in forestry to the position, and is well-informed of the issues and opportunities before us on the College Forests," said College of Forestry Executive Associate Dean Steve Tesch.

Mann built a 35-year career in the forest industry, including serving as vice president for both the Western Region of the Forest Engineering Research Institute of Canada (FERIC) and Timberland Operations for the TimberWest Forest Corporation in British Columbia, Canada.  After retiring in 2008, Mann, who graduated from the OSU College of Forestry in 1979 with a Master of Forestry degree in Forest Engineering, returned to the College in 2010 to serve as the Director of Cooperative Education in the Forest Engineering, Resources and Management Department.

Yellowstone transformed 15 years after the return of wolves

The return of gray wolves has dramatically altered the landscape in portions of Yellowstone National Park, as new trees take root in areas where the predators have curbed the size of foraging elk herds, according to scientists in a new study.  Stands of aspen, willow and cottonwood are expanding in areas where for decades dense elk populations prevented new growth, said study author William Ripple from the Department of Forest Ecosystems and Society at Oregon State University.

Fuel reduction likely to increase carbon emissions

Forest thinning to help prevent or reduce severe wildfire will release more carbon to the atmosphere than any amount saved by successful fire prevention, a new study concludes.  There may be valid reasons to thin forests – such as restoration of forest structure or health, wildlife enhancement or public safety – but increased carbon sequestration is not one of them, say scientists including Forestry researcher John Campbell and professor Mark Harmon

Thinning Oregon forests develops spotted owl habitat, chases away flying squirrels -- the owls' chief prey

A new study by Oregon State University researchers indicates that thinning Douglas firs, which gives them more room to grow and develop the old forest characteristics favored by northern spotted owls, is bad news for the threatened bird's primary prey.  The report was written by Tom Manning, Brenda McComb and Joan Hagar, with College of Forestry's Department of Forest Ecosystems & Society.

Christmas trees get greener with new certification

A new sustainability program for Christmas trees, developed in part by the Oregon State University Extension Service, debuted this season.  For the first time, consumers can buy trees identified as the product of a Socially and Environmentally Responsible Farm. "A SERF-certified tree assures you that this real tree is grown using the best and safest methods known," said Chal Landgren, a Christmas tree specialist with OSU Extension, in a press release.

Research Study Focuses on Beavers and Landowners

Oregonians know a lot about beavers and in general, they like them.  “We were surprised at how knowledgeable so many people are about beavers,” said Associate Professor Dr. Mark Needham of the Department of Forest Ecosystems and Society at Oregon State University who recently completed a survey designed to quantify landowner attitudes toward beavers and about allowing them on their property. This statewide survey drew responses from more than 1,500 people.

How A Tiny Fungus is Starving Coastal Douglas Fir Trees

In 2008, scientist and College of Forestry assistant professor Bryan Black took core samples the diameter of a pencil from a forest near the north Oregon coast. Most of the trees were hemlocks and Douglas fir that had been undisturbed for about 90 years.  The trees had a particularly severe case of Swiss needle cast, a disease caused by a fungus that infects Douglas fir needles and starves the trees of carbon dioxide.
