SALEM, Ore. (AP) — A timber investment firm is selling more than 3,000 acres of land along the Columbia River that has been used to grow poplar trees.

Greenwood Resources, an investment company that owns and manages forestland, is selling off the final 12 parcels of what was once part of a much larger 31,000-acre poplar operation in Oregon and Washington. The poplar trees were planted to be later sold for the paper industry, but stiff international competition and a low profit margin made that difficult.

The minimum bid for the all the Columbia County properties combined is nearly $8 million, but potential buyers may also bid on individual parcels ranging in price from about $100,000 to $2.6 million each. Sealed bids are due by Nov. 13.

Roughly 2,000 acres still have poplar trees growing on them, more than 500 acres are fallow farmland and the remaining acreage is considered “non-commercial” land that can be dedicated to wildlife habitat and recreation.

Nearly 1,400 acres have water rights for irrigation.
