of approximately 20,000 km², this species is only facing minor threats that are not severe enough to warrant a threatened category. Historical land clearing for agriculture have left its range fragmented, though this has now ceased. It is currently threatened by weed invasion and clearance of roadside verges where many populations occur. The population is currently believed to be stable and it occurs in multiple nature reserves. It is also classified as " Priority Three" by the Government of Western Australia
