Western Australia's "Wheatbelt" is an expansive agricultural area created by widespread clearing of native forests beginning in the 19th century and still continuing today which has vastly modified the pre-human landscape.

However, there are many more-or-less pristine nature reserves (often associated with granite outcrops) scattered throughout the region where 12 southwest species of frogs thrive. This region contains many arid-adapted species in the eastern and northern edges.  For instance, five species of Neobatrachus occur here.
