It is an ecosystem, not just a bunch of trees. In those mountains, it means flooding, erosion, other species taking over, loss of livelihood. The whole place has to readjust to get back to being old growth.
When you blade off a piece of desert here, it takes about 400 years for it to recover. Down there, in that forest, this is comparable to a major forest fire devastation, only without the natural barriers and left overs that usually sustain the system. Thing is it isn't natural like a forest fire. It is much more bio-diverse than the forests back east. It is more complex. It hasn't had the diversity cut out of it and it has adapted to different conditions. Maybe you need to visit there and get educated, or take an ecology course and ask around. Three kinds of big cats, dozens of different kinds of trees in a single plot, interactions between species, then some outfit comes in and treats it like it just a bunch of trees that will grow back, but they don't care if they grow back. The succession is crippled and has to take place again. Miles and miles of clear cutting.
