It was for a USFS program that was finding and propagating better trees. The idea is that the seedlings that got planted after logging or a fire would be the best available, not just random junk that looked like a tree. The program had been going for many years before I worked for it and is still going.
Yes. National Forests in the Sierras extend for 40-60 miles and butt up to the next National Forest to make a chain that's hundreds of miles long. There's very little private land and nearly all of it far was away from the parts we worked in. Unless there's a recreation area of some kind, the only activity is logging. We knew nothing was going on down range. It's probably not something you'd be able to do safely in a lot of eastern forests, or where I live now for that matter. I wasn't suggesting it for the OP, just telling a story.
