Oron, do you know why Eucalyptus camaldulensis was chosen as the tree to plant in an arid area? Its common name is the River Red Gum because it grows right on the banks of permanent rivers and creeks, and also summer dry water courses which still have water underground year round. In many cases the trees grow in the water, or are frequently inindated for months at a time. Indeed, the flooding is necessary for regeneration by seeds. Mature trees, around 300-500 yrs old are just HUGE. Some much older trees are hollow inside with large enough cavities for families to occupy as temporary homes (with canvas tenting to cover the holes). These trees are 800 yrs old and older. Google 'Herbig Family Tree' and I think you'll find some information and photographs. tn.
