Do you have figures and a link? I regularly drive through Oregon, Washington, Idaho, Montana and I see a lot of private timberlands either burned or killed by beetle infestation/drought; especially in western Montana. Locally, I see a few private plantations burned over. What you say makes sense, since these modern plantations have very little fuels buildup on the ground, and very little understory; but I would have to see actual acreage. And let's not forget, the federal lands include parks and wilderness where lots of people are camping, and firefighting may be a lot harder or constrained by regulations.
