Question Without Notice No. 808 asked in the Legislative Council on 13 September 2018 by Hon Dr Steve Thomas

Minister responding: Hon S.N. Dawson
Parliament: 40 Session: 1

Answered on 13 September 2018


808. Hon Dr STEVE THOMAS to the Minister for Environment:

The minister has been waiting for this one! I refer to the declared weed arum lily, Zantedeschia aethiopica.

(1) What area of land managed by the Department of Biodiversity, Conservation and Attractions is currently infested by arum lily?

(2) In the last 12 months, what area of land managed by the DBCA that is infested by arum lily has had remedial action taken to remove arum lilies?


I thank the honourable member for some notice of the question.

(1) Given the level of detail required, I request that the member put this part of the question on notice.

(2) The Department of Biodiversity, Conservation and Attractions' arum lily control work is prioritised in areas with high conservation values. Typically, large infestations, especially those occurring across tenure, are not managed for eradication but will be managed to stop further infestation. An estimate of the remedial work on arum lily infestations carried out on DBCA-managed lands in the last 12 months is: in the Swan region, approximately 9.12 hectares treated in DBCA's Perth Hills district; and in the south west region, approximately 40 hectares treated in DBCA's Blackwood district, focused on protecting threatened ecological communities.
