I think the correct way to go about this is to just encourage people to plant trees suitable and native to their (people's) environment. And let it scale. Better, also tell them not to fell trees left right and center.

In the exuberance of ecological conservation and all that, we must not overlook and override what nature would have done. For instance, one shouldn't plant a water sucking tree where it wouldn't naturally occur, and damage the balance.
