That’s a lot of trees. But it says they have drought problems…I hope they realize new trees usually need a lot of water.
There are many ways to combat drought. PLanting trees is one of them.
Good on them.
Now they just need to make sure the local fuckwits don’t cut them all down again.
Depending on exactly how the trees were planted, what species they are, and whether it’s the rainy season right now, they may well have a reasonable survival rate even without any real care. 5-10% would be “reasonable”. Once you’ve established a modest amount of tree cover, other species will naturally move in all by themselves.
Wow, those seems low.
It’s fine. I had the devil of a time trying to establish trees on an area of burned-out land. Most of them died. However the few that survived are now doing well, and I’m assuming those are the ones genetically suited to that location, while the dead ones were not. In the microclimates created by those trees, other plants are springing up. Nature can fix things pretty quickly if you give her a foothold.
Even if only the above suggested 5% thats millions of trees. I assume they planted pioneer species, grasses etc as well. Ince a large enough expanse of land has vegetation, just the transpiration will cause humidity, dew and water collection. It becomes its own microclimate. Its a big reason so many replanting schemes fail in arid areas (aside from poor variety selection) is simply lack of size. Hundreds, or thousands, of kilometers can make an impact. Planting roadsides is just buying votes.
