#2Who would have thought that replicating nature would yield the best results...
The Miyawaki method is probably relevant to this discussion - https://www.creatingtomorrowsforests.co.uk/blog/the-miyawaki...

#3The other way to do this is to leave seed trees on the block in addition to replanting with 3-4 other species. They do this in British Columbia now.
When a block is logged, cones from that block are taken to regrow seedlings to plant there. It doesn't work as well if you try to seed from different elevations or far away areas.

#4Someone logged a 500 hectare plot in Borneo. They split this into 125 sections and planted 0, 1, 4, or 16 "tree species that are frequently targeted for logging". After 20 years, satellite imagery shows that the more tree species you planted, the more recovered the land appears to be.
I'm left wondering:
1. Why did they plant only tree species that are frequently targeted for logging? This makes the whole experiment very suspect. The linked article talks a lot about restoring forests, but why restrict the tree species to those that are profitable to log?
2. Is the satellite imagery actually representative of on-the-ground truth? A lot of logging land in western America gets replanted with logging-friendly trees in very regular grid patterns. These areas may look like forests from satellites (or to uninformed ground-level visitors), but the regrown tree farms do not behave like forests. The dense growth crowds out the ground-level plants, which in turn makes the entire tree farm a poor habitat for local fauna. If your goal is to grow more trees for lumber, tree farms are great. But I'm not sure the claims about "forest restoration" are honest/true here.

#5Eventually people will figure out that monoculture was a horrible and anti-nature idea.

The issues from the Great Green Wall [1] are worth looking at

Between clear-cut horror and ideal pristine old growth, there is a world of managed forests that fix carbon with an economically sustainable model. Not the best biodiversity but mixing sixteen species makes the initiative top tear already.

Because the whole point of tree planting is forest management. That's why whenever there's a forest fire they spray it with glyphosate so that other trees don't grow, then they plant GMO trees that can live in glyphosate doused soil.

#9How is this not a complete and obvious no-brainer? As advanced as our culture is in some ways, it is clearly quite idiotic in many other ways.

#10The Curiosity Daily podcast had a related topic this past week. There are plans to plant 1 billion (or 1 Trillion) trees at various levels of government (WEF is the 1Trillion number). So researchers went out to try to find saplings from local nurseries that could supply the diversity of trees that would be needed. They found that less than half the nurseries could supply saplings - and very few were 'climate change friendly' saplings, most were decorative or other non-climate-friendly trees.
