Southwest – Wheat Belt Frogs
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.
