Forestry is hard. If you plant the wrong species, in the wrong soil, with the wrong fertilizer or in the wrong climate, you are likely to completely fail. Early attempts at forestry often ended up with every single one of the planted trees dying. Luckily forestry is a pretty seasoned science by now and people mostly know what they are doing. I trust that the Ethiopian forestry scientists did their job though before this and they end up far more successful then these early attempts, before the science was known.
