Fatih I live in Indiana, USA and our average rain fall is 40 inches. I have Sycamore trees that do well and Elm that are dying off from a tree borer. I have seen a town in Utah, USA with both sides of the street all the way through town that was planted with Sycamore trees and nothing else. Not far outside of this town was salt desert and much of Utah's rainfall is in the 16 to 18 inch range. Whether the Sycamore's were watered in the town, I don't know. I would look for local trees in your area that are doing well and plant them.
