If the federal government were to sell all 84 million acres of national parks — valued at $92 billion according to a new study — it would barely make a dent in the country’s $14 trillion debt.

Still, the National Park Foundation analysis for the first time puts a value to the lands protected by the 100-year-old National Park Service, an amount that’s more ceremonial than an actual price tag.

“Even though national parks are priceless public assets, it’s important to estimate how much the American public would pay to protect them,” said professor Linda J. Bilmes, the Daniel Patrick Moynihan Senior Lecturer in Public Policy at Harvard Kennedy School at Harvard University. “This study is a birthday wake-up call that shows Americans value the NPS at least 30 times more than the government spends on them.”

The study was conducted by John Loomis, a professor of agriculture and resource economics at Colorado State University, Michelle Haefele, a post-doctoral researcher at CSU, and Bilmes.

The study also found that 95 percent of Americans said protecting national parks for future generations was important, and 80 percent would pay higher federal taxes to ensure the protection and preservation of the National Park System, the foundation said in a press statement announcing the findings.

“This study demonstrates that more than half of the total economic value of national parks is attributable to the benefits the American public receives from just knowing the National Park System is protected for current and future generations,” Loomis said in a statement.

The foundation is the fundraising arm of the park service and is working on a campaign to raise $350 million in celebration of the service’s centennial.
