1-866-INVADER’s Greatest Hits
By — Posted
It takes many eyes to spot all the invasive pests, plants and pathogens that might possibly come into Oregon and cause damage. That’s why, 15 years ago, the founders of the Oregon Invasive Species Council decided to enlist the public’s help. They set up a hotline at 1-866-INVADER, where people could call in and report […]
Website educates public on invasive pest threats
By — Posted
Although the agriculture community is well aware of invasive pests and pathogens — including the emerald ash borer, sudden oak death, the giant African snail, the citrus psyllid, the Asian longhorned beetle and many others — agriculture cannot fight them alone. These pests can be transported unwittingly by the general public; therefore, public awareness is needed to […]

High fructose corn syrup may harm honeybees
By — Posted
What is causing honeybee colony collapse disorder? Scientists have been trying to find the answer to that question. A new study suggests that feeding high fructose corn syrup to honeybees might compromise their immune systems and diminish their ability to fight off toxins. Earlier studies, done decades ago, had suggested that feeding these pollinators corn […]
New USDA zone map released

Study: Climate change reshaping Northwest forests
By — Posted
As you drive around the Pacific Northwest or other regions, have you ever noticed that the makeup of the forest changes when you drive from region to region, gain or lose elevation, or cross over a mountain pass?
