This is a painful topic to those of us who grew up in the PNW (or, I assume, in other forested areas). I can see three national parks from my office window, and most everything else in between is national forest. We grew up playing, fishing, hunting (wasn't my thing, but certainly friends did), and - most of all - hiking in them. To this day it is where I'm happiest. I recall the days of actual clearcutting right down to the streams, rivers, and highways, and would so hate to see that return. Nowadays they have to leave buffers and replant, which doesn't replace the more mixed natural forests but is a renewable resource and as such is likely to continue. Selective logging is best but is still fairly rare.
The lack of sawmills is definitely a thing out here as well, at least in WA. Oregon is still a resource colony WRT timber and probably have more remaining. When I was young two places all the kids in Seattle went to on field trips were a salmon hatchery and a sawmill. Both are ingrained in us as part of our home. The hatcheries are still there; the sawmills, since the early Reagan years, are mostly gone. Now raw logs are sent to Asia for milling and their use. Our lumber comes from Canada - easy enough to see the trains and trucks rolling through Seattle.
Mass timber construction will continue to grow; building codes have very recently been updated to allow for greater use, even in high-rise construction, and there are now local wood product manufacturers here again to produce those materials. As mentioned above, though, stick frame/dimensional lumber will still dominate the construction market for some time to come, and Canada has the mills. Like manufacturing elsewhere in this country, it effectively no longer exists here - certainly not as it once did.
