This species is of major concern as populations are disappearing at an alarming rate. The likely causes of decline are isolation of populations due to land clearing and associated small population sizes exacerbated by low natural dispersal. Fuel-reduction burning in spring has been associated with a significant decline in the number of calling males. Populations had not recovered two years after fire and the short-term impact of spring fuel-reduction burns may pose a serious threat of extinction for very small populations. Another threat are feral pigs which occur throughout south-west Western Australia and are capable of causing severe localised soil disturbance.
