This is a vast, dry region of red sandhills and desert grass. On these so-called "buckshot" plains, the soil is sandy, iron-rich, and deeply weathered. Here, mulgas, an evergreen eucalyptus shrub with yellow coneflowers, grow alongside clumps of hardy Triodia grass and other drought-resistant shrubs. After one of this ecoregion’s rare rains, these small shrubs will flower in a brilliantly colorful display.
The Gibson Desert is bounded on the north by the Great Sandy Desert and on the south by the Great Victoria Desert. To the west lies Lake Disappointment, a large saline lake that is no disappointment for the many waterbirds that congregate there, seeking refuge in an otherwise arid environment. The characteristic gravel rises of the Gibson Desert led one early explorer to call it a "great undulating desert of gravel." The endangered greater bilby, a small, rabbit-like animal with large ears and a delicate, pointy snout, emerges from its den at night to search for food. The bush stone curlew (a bird) is most active at night, too, when its mournful, eerie cry rings out over the desert. Red kangaroos may be seen during the day, traveling in small social groups led by a dominant male. Large, flightless emus hunt for grains and insects, while the small striated grasswren flits about the Triodia grass. The emu once provided an important source of protein for Aborigines who lived in arid areas.
This region is mostly uninhabited except for Aboriginal land. Some sheep and cattle grazing occurs on the margins of the desert. Feral and introduced animals are also concerns.
