When going out with Phil Maher to find the Plains Wanderers near
Deniliquin Phil spelled out to us the habitat requirements of the PWs.
In the current environment they need very sparse grassland vegetation
which allows growth of certain native 'forbs' (grassland herbs), whose
seeds they feed on. In the paddocks around Deniliquin apparently they
are only found in certain patches within paddocks where occurrences of
certain soils allow for this veegetation. If these patches occur then
it seems they can co-exist with cattle and sheep grazing.

Where they occurred in the pre-European context is difficult to guess,
perhaps on soils which only support sparse grass growth with marsupial
grazing. It sounds as though it's not sparse grass per se which they
need, but they need the seeds of the herbs and have learnt to survive
in the open whereas, perhaps, quail and button-quail cannot survive so
successfully in this vegetation, and so can't compete with them?
