But Agriculture Undersecretary Mark Rey, who directs forest policy, said the parcels to be sold are isolated, expensive to manage or no longer meet the needs of the national forest system. The administration expects to have to sell only about 200,000 of the 309,000 acres identified Friday to meet the $800 million goal, he said.

"These are not the crown jewels we are talking about," Rey said in an interview. The public can review the land parcels that are up for sale on the Forest Service's Web site, Rey said; Maps of just four national forests were posted as of Friday, but Rey said all the properties should be posted by month's end
