Distribution and Habitat
This frog is endemic to a limited a strip of land along the coastal zone in southwest Australia within the Southwest Australian savanna ecoregion, including the arid zones from Shark Bay (Edel Land) southward to the Murchison River of Western Australia (Hero and Roberts 2004). A. rotunda also occurs on Dirk Hartog Island. The estimated altitudinal range of the species is from sea level to 150 meters above mean sea level. Population densities have been estimated as great as 277 individuals per hectare (Tyler 1998).
A. rotunda chiefly occurs in limited extents of the coastal dunes of the Southwest Australia savanna. Principal habitats are comprised of course-grained sand. This fossorial species requires no standing water in any form for its survival or breeding; however, residual soil moisture retained in dunes soil is critical for the survival of this anuran, particularly due to the arid climate and its sparse mercurial precipitation. Biomass density of this species has been estimated at 530 grams per hectare (Tyler 1998).
