There's about one month remaining to submit proposals to buy Oregon's Elliott State Forest.
The Oregon Department of State Lands says so far, no one has expressed interest in the 82,000 acre property in southwest Oregon.
The state values the land at $220 million and says whoever buys it would have to maintain public access on at least 50 percent of the site. The new owner would also have to preserve part of it for old-growth timber and protect fish habitat.
But some conservation groups say those guidelines will be hard to enforce if private investors buy the land.
"From fishing and hunting opportunities, to hiking, to birding, to the clean water, to the carbon storage to mitigate climate change, this is a forest that needs to be retained in public ownership," said Josh Laughlin, executive director for the conservation group Cascadia Wildlands.
Laughlin was part of a group that rallied outside a meeting of the State Land Board on Tuesday in Salem.
The board is expected to review any possible proposals to buy the Elliott at its December meeting. Money from a sale would go to Oregon's Common School Fund.
