Forest study in China finds mix of trees can absorb twice as much carbon as areas with one species
More than 60 scientists from China, Switzerland and Germany were involved in the research, testing a hypothesis based on observations in the field.
“The study shows that forests are not all the same when it comes to climate protection – monocultures achieve not even half of the desired ecosystem service,” Schmid said. “The full level of mitigation of global warming can only be achieved with a mix of species. In addition, species-rich forests also contribute towards protecting the world’s threatened biodiversity.”
Such forests were also less vulnerable to disease and extreme weather events, which are becoming increasingly frequent as a result of climate change, Schmid said.

That might well be an underestimated aspect. We don't know how climate will change locally, what pests will spread where, what species will turn out best adapted to future conditions, or what species turn out to be keystones in specific ecosystems. So we should strive for having as diverse a set of flora anywhere. Success factors are varied, complex & interconnected.
Climate changes so fast that past 'performance' of species in an area is of little value. Those trees are going to stand there 20, 50 or 100y from now. What will local climate be then? Take your guess / throw the dice.
Simard proved that deep rooted trees pull up water that ends up in shallow rooted plants, and that evergreens share sugars with deciduous trees in early spring, and then the direction reverses during the height of photosynthesis. Specifically in the case of water, the trees cannot transport enough water to keep up with peak transpiration, so they slowly dry out. But all night long they're still pulling up more water, more than they can use, more than they can store, and some of the excess ends up in their neighbors, through capillary action or the rhizosphere.
There’s an implication of intent here, regarding plant-to-plant transport and fairness, that I think is more likely explained by osmotic pressure. Entropy itself is 'fair' in this regard. Fungal hyphae aren’t designed to manage huge nutrient or water gradients. In fact they seem to be designed to communicate information at an alarming speed. Which we still do not entirely understand.
I didn't. But there's no reason why it shouldn't work there.
