The potential distributions of Asparagus asparagoides and A. declinatus in the south-west of Western Australia are predicted from the climate of their known distribution in South Africa and elsewhere in Australia. Both species show the potential to considerably expand their range in the south-west. Recommendations are made that both weeds be declared noxious and that an eradication program be undertaken against outlying northern populations of A. asparagoides and the two known infestations of A. declinatus.
