Hi Kostas,
I was looking to see what was available in the tree world,just whatched a youtube vid about Spain begining to lose its soil due to tree removal etc.Your sugestion of walnuts trees seems a good one.Obviously this will take decades,but we need to repair the past mistakes for the land to be able to hold its own against the wind and sun.
Thanks Kostas,will make your sugestion to the people of Almeria,Spain.
kind regards Paul.
