Logging practices are very careful to conserve all sorts of root systems. As fast as the trees come down ( just a "fiber crop" in most circumstances), summer replanting is always well up into the millions. Billions total by now. Yes, you are being watched.
The biggest issue has been the tremendous range fires over the past couple of summers which have killed all the plants so soil cohesion is gone. We don't have soil or dirt like you do. 6-8" needle duff organics (burnt now) on the forest floor and clay/sand/rock under that. Does not take much water to grease that up and away the mountain side goes. 70kph wall of rocks, mud, water and smashed logs, here it comes.
Some of our highways have stretches carved into quite steep mountain sides. A few days of local big rain to grease that up and trees or no trees, the entire highway takes off down the mountain side. A friend of mine lives a charmed life. She has witnessed that **** happen in her rear view mirror.
