I thought these pics were interesting, showing the type of substrate + surrounding vegetation in
the territory of pogona vitticeps. Note that there actually is a lot of loose sand/clay/type on top of the hard packed earth in their territory, not very rocky in most instances. There are also captive beardie pics in this group as well which are pretty obvious.
