MixedForest
Not sure if you came across, but I did came across govt schemes and private plans to do agro-forestry. Nothing but growing series of trees in mono-culture way, forest by definition only. On paper forest.
Mixed forests are more productive than monocultures. This is true on all five continents, and particularly in regions with high precipitation.
Reforesting strategy by GDP-driven society and govt will always be based on economic value of the trees. So, they will plant only economically valuable trees. Not only that, they will also apply mono-culture approach used in modern agriculture.
 
What is naturalized, cannot substitute natural. Simple. Period.

Mixed forests: ecologically and economically superior

“We know of the many advantages of mixed forests,” states Professor Hans Pretzsch, co-author of the study and author of a recently released, internationally acclaimed book on the ecology and management of mixed-species stands. “Mixed-species forests are ecologically more valuable as versatile habitats. They mitigate climate change, as they mean a higher carbon sink.”

Trees in mixed-species forests are often better supplied with light, water, and soil nutrients via their complementary crown and root systems. “This makes mixed stands more resilient during dry years. In addition, they are more stable against pests and visually more appealing,” adds Prof. Pretzsch from the Chair of Forest Growth and Yield Science in Weihenstephan.

But these arguments alone have not yet managed to convince forestry management to promote mixed-species stands. This meta-analysis and overview study now shows that a prudent selection of the combination of tree species leads not only to more ecological and resilient forests, but also to greater productivity, explains Pretzsch. The study documents that mixed stands perform better in terms of productivity than monocultures, particularly in areas with favorable water supplies, such as in Central Europe.
