idk what the previous commenter means by it, but to me, a forest is more than a collection of trees that are planted in a grid, ready for clearcutting in a decade or so. A forest is an entire ecosystem that takes decades to build without the disruption of human intervention. Some of these "managed forests" are little more than tree farms, lacking the wildlife and diversity that comes with natural forests. Monoculture tree farming does not create a diverse ecosystem and the benefits that come from that.
