CHARLOTTESVILLE, Va. (AP) -- Officials at Shenandoah National Park are working on a plan to stop the spread of chronic wasting disease.
The Daily Progress reports that the plan could include thinning the park's heaviest populations of whitetail deer.
Park officials also plan to increase surveillance and detection of the disease, which affects the brains and nervous systems of deer, elk and moose.
Park biologist Rolf Gubler says the disease has been detected in deer 25 miles from the park's northern border.
Deer in Frederick and Shenandoah counties have been quarantined. But Wildlife Center of Virginia president Ed Clark says the disease likely will spread beyond the quarantine area.
Virginia's first case was detected in Frederick County in 2009.
