I'm guessing you aren't from the U.S. but in the southern U.S. growing newer species of Pine (variants of Loblolly Pine). A standard lease is 20 years from seedling to harvest, some older variants can go 30 to 50, but you don't see that being planted any longer and that's all leases maturing.

And here, I can assure you they are very much mono culture, evenly spaced, engineered species of trees, almost nothing else happens on the land in that time period. (generally it looks pretty similar to this https://a.rgbimg.com/users/p/pa/paparabbit/600/mwYGk8q.jpg) They do come and selectively thing at 5, 10, or 15 depending)

See the issue is, at least in the southern U.S. they clear cut nearly everything in the 1800s. There is very little old growth left.

Yes they used to do forestry like that in Northern Europe. They realised the methods described by the OP are more sustainable and more reliable (e.g. diseases will wipe out monocultures).

I agree with it being better for the world in a lot of ways. And I would like to see it change, but it isn't likely to, at least not for a really long time.

P.S. As for mono culture timber, there is a reason almost no one in the US knows what a curant is. They (are/were) illegal in the US, because they are for a vector for a fungus that can wipe out timber pines.

"See the issue is, at least in the southern U.S. they clear cut nearly everything in the 1800s. There is very little old growth left."

I pity them. Real forest is something very different, than a wood farm.

With the recent droughts and dying out of the monoculture spruce, more and more mixed forest is coming back to europe. Idealism brought a little change, but the big drive was the huge economical loss of the timber industry that forced them to rethink how to do things.

We lost every ash tree in Ohio in the last 10 years some places it was 40% of the entire Forest

Ok, but that's still not 10 years.

There is a middle ground between the monoculture you describe and old growth. You can have an intact ecosystem with something every biologist would call "forest" even if you now and then strategically harvest some trees. We are almost 8bn people on this planet and we can't make do without lumber. All alternatives are much worse. Want to use plastic for everything? Steel? Concrete? We need to find a sustainable middle ground.

Linville Gorge being a notable exception:

Interesting. I've never seen anything like that in the Northwestern US.
