The emerald ash borer, a beetle pest that has devastated ash trees throughout the eastern United States, was officially detected in Greenville, Oconee and Spartanburg counties in August 2017. According to a Clemson University press release, the beetles were found Aug. 3 during a routine check of Emerald Ash Borer traps and confirmed by the U.S. Department of Agriculture. In response to the discovery of EAB in the Upstate, the State Crop Pest Commission likely will establish a quarantine area involving at least the three affected counties; it is also possible the quarantine could be expanded to additional counties or even the entire state.

Tribal, state and local governments will join forces at Lake Roosevelt this week to combat the spread of northern pike, recently recorded just two dams away from critical Columbia River salmon habitat. “We are at a critical moment in time where northern pike have not spread into salmon habitat,” said Kelly Susewind, director of the Washington Department of Fish and Wildlife. “If northern pike move downstream, the State of Washington will consider this an environmental emergency. We need to work together to stop northern pike.”
