Another problem to face in the salt laden wind, salt water also affects the hydration of the plant. If the salt content is high the water in the leaf cells will diffuse out of the cell, dehydrating the cell. The cells of Pohutukawas have special features in their cells that remove the salt from the cell before it dehydrates itself. Pohutukawas grow slowly, this means their body is very strong and dense which enables them to face the strong winds that are present in the coast. They also have ‘wandering’ roots, their roots travel away from the tree finding any nook and cranny they can, this makes it possible for Pohutukawa to anchor themselves on steep and cliffs and rock faces.
