A new study out of Oregon State University suggests that overgrazing could be helping an invasive grass to flourish. That differs from previous studies that have found grazing can better manage that plant -- cheatgrass -- which threatens rangeland habitat. For EarthFix, Courtney Flatt has more.

Invasive zebra mussels could soon be heading toward the Pacific Northwest. So, researchers are working to protect and prepare the region’s waterways.

A boat that washed ashore on Gleneden Beach near Newport on the Central Oregon Coast appears to be debris from the March 2011 Japan tsunami.

National park officials have abruptly closed Crater Lake to scuba divers. They say they need time to develop rules to keep invasive species out of the Southern Oregon lake. Amelia Templeton of Earthfix reports.
