PORTLAND, Ore. (KOIN) — Millions of acres of public land in Oregon could be sold under a new proposal, according to lawmakers.

Oregon Sen. Ron Wyden and Sen. Jeff Merkley have called attention to a new provision of the One Big Beautiful Bill Act, which President Donald Trump's administration claims would lead to America’s “largest tax cut in history.” As part of the bill, the U.S. Senate Committee on Energy and Natural Resources has proposed the offloading of several assets owned by the Bureau of Land Management and the U.S. Forest Service.

But not every state would be impacted. The drafted legislation lists 11 Western states with land that would be eligible for sale: Alaska, Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.

The Wilderness Society has created a map that estimates more than 21.7 million acres of Oregon land would be up for sale. In Washington, conservationists have estimated more than 5.3 million acres would be available.

“If you’re wondering what billionaires will do with all their avoided tax in the Republicans’ bill, then look no further than this insane idea to sell off massive amounts of public lands for ‘housing,’” Sen. Wyden said of the proposal. “Read that as housing for billionaires, not nurses and firemen who will get stuck paying more taxes, more for food, more for utilities. There are no do-overs when it comes to selling off public lands. Once they’re sold, they’re lost forever.”

According to a fact sheet from the Energy and Natural Resources Committee, both BLM and USFS would identify the land that would be sold — but they would be required to sell between 0.5% and 0.75% of their inventory. The committee said this does not include “protected designations” like national parks and monuments.

BLM owns about 245 million acres of public land, while the Forest Service owns about 193 million acres. Proponents of selling this land are arguing it could help the U.S. close its housing supply gap of around 4 million residences and another 7 million affordable homes.

But Sen. Merkley has said he will “fight like hell” to ensure the proposal doesn’t come to fruition.

“Our public lands — which contribute to the spirit and economies of communities throughout Oregon and the country — belong to all of us,” Merkley said. “Republicans’ attempt to sell off our public lands, kick millions off of their health insurance, and make it harder for families to put food on the table — all to fund tax giveaways for billionaires — is a betrayal to families and communities across this country.”

The House of Representatives approved One Big Beautiful Bill with a 215-214 vote in May. President Trump has revealed he wants the legislation passed by July 4.
