invasive species

It may be difficult to eat our way out of the invasive species problem, but it can be satisfying to try.

Chefs and adventurous diners converged at Zenith Vineyard in Oregon's Willamette Valley near Salem Sunday as more than 200 people paid handsomely to nibble on course after course of invasive species like nutria, dandelion and carp.

The point of this affair was to highlight the range of edible invasive weeds, birds, fish and mammals around us. These invaders are costly to control. They crowd out native plants and animals and can change entire landscapes.

One slogan heard here: "If you can't beat 'em, eat ‘em."

A cold snap might be an effective tool for fish and wildlife managers trying to stop the spread of a tiny invasive species. Capitol Lake in Olympia is serving as a testing ground for freezing out New Zealand mud snails.

If you live in the Evergreen State, chances are, you like trees. Cities around the Pacific Northwest do a lot to protect them. 

But, do they really make us healthier? An economist with the US forest service in Portland is working on that question.

Geoffrey Donovan  loves trees. He’s already shown they make home prices go up, energy use go down and they tend to keep crime rates down as well. So what about public health?

People power is helping to clean up one of Seattle's most polluted rivers.  On Friday, about a hundred volunteers who work for the Boeing Employees Credit Union pitched in along the Duwamish in Tukwila. They’ve set a five-year goal of cleaning up two miles of shoreline.

Washington, Oregon and Idaho are joining forces to track populations of feral pigs across the Northwest. These “hogs gone wild” can do massive damage to the landscape. And wildlife agents want to know where swine are on the move. They’re even launching a so-called “swine line” for people to call with sightings.

When domesticated pigs escape their sties, Wendy Brown says something strange starts to happen …

“They actually develop darker fur, longer tusks -- they actually change in physical appearance. It’s amazing.”
