>>2838974well, the tree part I think is just different, the issues are more about resistance to fire (much less, I walked over a bunch of charred stuff), and really, the biggest difference is the undergrowth, removing all the trees allows unwanted scrubby growth to rule areas and you get vines choking out everything else and the terrain becomes impassible except on groomed trails or roads, whereas if you see old growth areas you can kinda go where you please because there's a lot less shit clogging up the understory - mostly just saplings and wildflowers.
I do wonder if they could "convert" the forest back into a recreation of old growth by removing the thickets and pruning trees that are competing ineffectively
it also used to be a lot darker in the forest before logging - it lets way more light through to remove the tallest trees although deciduous trees do make for a shadier canopy than evergreen ones, and putting skid roads and railroads through it diverts all the little creeks so you get less water flowing through the creeks and rivers after logging and the drainage is less efficient when you do
