Eucalyptus are usually regarded as fairly shallow-rooted species, but
some species go very deep in search of water (see figs 2 and 3):

I remember seeing large numbers of Eucs in Turkey, planted specifically
to soak up water. It was a long time ago and if I ever knew the type,
I've forgotten it. I do remember being intrigued as I'd always thought
Eucalyptus were trees that needed a little water, so using them as
sponges was a new idea to me.

Salt-tolerant eucalypts are also used to lower the water table in areas
where there is a high salt level. This can allow salt-intolerant
plants to grow in areas of low rainfall - it's the salt which kills
these plants, not the often drought-like conditions.

Thanks, Jeff. All I remember about this is that it was my first sailing
trip in Turkey and we were on a coach between Dalaman and Marmaris,
back when Marmaris was still a small fishing port, so around 1990, I'd
think.
