Beavers have long been punished by farmers because of their knack of flooding croplands and altering landscapes. But biologists are now trying to put those same skills to use on public lands -- for the benefit of salmon.
In December, 20 California bighorn sheep were released near the John Day Fossil Beds National Monument in Central Oregon. A video that shows the surefooted rams and ewes leaping across a snow-dusted landscape is only a few minutes long, but the event itself was 12 years in the making.
There's a very thirsty tree taking over much of central and eastern Oregon. Scientists say that in the heat of summer a single juniper tree can draw 25 gallons of water out of the ground. Oregon Field Guide's Vince Patton reports those trees are radically altering the landscape.
Tim DelCurto of Eastern Oregon Agriculture Center at Oregon State University says their range livestock research stations have studied use of stockpiled forages, windrow grazing and rake-bunched hay.
Some of the changing social values and demands to ensure species viability that ultimately caused the collapse of national forest management plans in the 1980s and 90s have been addressed, scientists say, but other topics still have similar potential for conflict.
According to an OSU study, medusahead is rapidly crowding out native grasses, and once established, it eliminates more than 80 percent of a land's grazing value.
Deciding to decommission logging roads isn't as simple as it might seem, said Julia Jones, a Department of Geosciences professor at Oregon State University. She's studied the hydrology of logging road runoff.
Oregon and the nation are in the throes of a population explosion of horses, both wild and domestic.
The study was done by researchers from Oregon State University and other agencies, and concluded that heavy loads of parasites can affect salmon growth, weight, size, immune function, saltwater adaptation, swimming stamina, activity level, ability to migrate and other issues.
The western United States has experienced increasing drought conditions in recent years "and conditions may worsen if global climate change models are accurate“ yet the country is doing little to prepare for potential catastrophe, a group of scientists said today.
No-logging zones along state forest streams are making a difference in keeping temperatures cool for fish, according to a study issued Wednesday by Oregon State University.
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.
Now an Oregon State University professor is studying algae strains at a series of Oregon waterways to determine whether these individual strains can produce toxins capable of sickening and killing people or whether they are nothing more than gross, smelly scums producing no greater public-health danger than swimmer's itch.
Oregon State University wheat breeder Bob Zemetra says several varieties in the development pipeline show promise.
A relatively new disease in the Northwest presents a significant threat to dryland wheat, Oregon State University Extension cereals specialist Mike Flowers said.
