I feel like the important part of these tree-planting initiatives is setting aside land for trees to grow. If you leave a plot of land alone, climate-appropriate plants will grow soon enough. You might have to do more in special scenarios like reversing desertification, but that's not generally the point o these initiatives, and the number of trees needed for that is much less.
