In progress:• North Flinders land managers

around Blinman called for a meeting to develop an OpuntiaControl Strategy in their area.

• This will result in a coordinated approach to Opuntia control across the landscape.

• The idea is to use biocontrol in denser infestations and chemical control on outliers and in areas where plants are sparsely distributed.

• DEWNR are involved in facilitating the development of this strategy and have provided maps detailing where control has occurred over the past decade.
