State land just west of Potholes Reservoir is again being closed so airborne federal sharpshooters can try to remove feral pigs there.
USDA Wildlife Services will use bait and helicopters to kill any of the unwanted invasive species on 1,300 acres of the Desert Unit of the Columbia Wildlife Area starting tomorrow, Friday, July 29, through Aug. 31.
Any swine shot will be genetically sampled to try and determine their origin.
WDFW says the operation is being done during the part of the year when the wildlife unit sees the least usage from sportsmen and others. Signs designating the closure area will be posted.
The area will reopen for the Sept. 1 start of hunting seasons.
Part of the wildlife unit was also closed in late February and most of March for a similar effort.
Reports of feral hogs here first started surfacing last September. WDFW staffers killed at least four during off hours, while a Wildlife Services hunter killed a fifth.
