There is one tree that comes from Australia (or from that neighborhood)
named "Casuarina equisitifolia", I've seen it forming thick windbreaks
and it has been used for sand dune control in irrigated lands in semi-arid
regions (in my hometown). It works also in controlling seashore sand dunes.
I've seen plantations of it from the sea level to 2500 m, and from sandy
to rocky soils. I don't recall seeing it sprouting, and at least in
those places where I saw it, doesn't have an easy seed reproduction.
