Permaculture niche: Dry Climate Trees

Over a month ago, there was an interesting item on Gardering Australia. It featured a visit to the Waite Arboretum in Adelaide.

It highlighted a group of plants I feel fill a permaculture niche not filled by Australian natives, large deciduous dry climate trees. I had been looking to the Med Basin, particularly North Africa.

Here is a batch of links.
