Half of timber land in the US is privately owned and in small plots. Most of that is sustainably harvested. Weyerhaeuser is the largest landowner in my state with something like 10% of the land. They clearcut in plots about every 20 years but they do a good job of only doing small bits at a time. There’s plenty of wildlife because they plant scotch pine and not spruce, which does not support a healthy wildlife ecosystem.
