Unique habitat of ancient olive trees in Deir Hanna


The Deir Hanna antique olive trees are well known for their impressive stem and crown diameter. A survey of their unique habitat was executed in 2015. The trees roots penetrate a porous soil layed upon marly chalk. Under the chalk an aquiclude made of marl horizon. Part of the underground water appear in a small spring down the slope. This specific geological structure increased trees vitality and survivorship through the centuries. Recent hydro-mechanical operations made to increase the flow in the spring, might reduce water availability and could risk the trees survival in the future. To an Hebrew atricle touch here
