The striking arid landscape of the Mount Willoughby IPA was dedicated in 2002. Covering 420,672 hectares, the IPA is situated over two bioregions — where the Stony Plains of the Kati Thanda-Lake Eyre Basin meet the Mulga shrub lands of the Great Victoria Desert.
The Mount Willoughby IPA consists of a diverse range of habitats, including the cracking clay pans of the Moon Plain, gibber plains, breakaway ranges, emu bush and mulga country, swamps and dunes and is home to a number of rare and endangered species.
The Mt Willoughby Rangers and the Traditional Owners, the Antakirinja Yankunytjatjara people, are committed to documenting and conserving the significant cultural heritage values across the IPA. Prior to becoming an IPA the land was intensively farmed for well over 100 years and the rangers are now concentrating on land management to protect the habitat from feral animal and weed infestations to encourage regeneration and the return of native species.
