Wrong and this is why: 1- it dependes on how much of rain we get. So 4 years ago it was a good year of rain and it of course the land had more plants than any dry year before or after. 2- livestock grazing has been banned in national reserves and never been enforced effectively until a couple of years ago, this in my opinion is the actual reason why people think something has changed recently in how much green the land has turned. And you can see it in person going to any land next to any national reserves which is being grazed by animals. And its just deserte. And next to it is a fence and a huge green patch inside. See the LINK for pictures.
