The Hon. GREG PEARCE: On 30 May 2012 the Hon. Robert Borsak asked me a question about the Noogoora burr infestation at Toorale Station. The Minister for the Environment and Minister for Heritage has provided the following response:

I am advised as follows:

Since establishing Toorale as a national park and state conservation area, National Parks and Wildlife Service staff have undertaken annual control of Noogoora Burr by way of chemical treatment, slashing and manual removal of plants. This will need to continue given the reinfestation which occurs from upstream sources. Additionally, treatment of Noogoora Burr, like most weeds, is most effective during summer months.

Questions without notice concluded.

Pursuant to resolution Government business proceeded with.
