A Wilderness Society report shows that Idaho has sold off about 1.7 million acres of land for development—a portent of what could happen if special interests are allowed to seize national public lands in the state.

According to the report, Idaho’s 1.7 million acres of sold-off state lands have included more than 100,000 acres sold since the year 2000. In many cases, these sales have cut off public access to cherished outdoor recreation spots or even allowed lands to become industrialized.

The findings serve as a repudiation of politicians who want Idaho to seize national public lands but deny that this will lead to these landscapes being privatized or sold off to corporations.

“National forests and other public lands are a cornerstone of Idaho’s heritage. They’re the places where we hunt, fish, camp, hike, bike and where many Idahoans make a living,” said Brad Brooks, The Wilderness Society’s Boise-based deputy regional director, in a statement. “History is clear on what will happen if our national public lands are given to the state. They’re almost certain to end up in hands that will lock the public out.”
