Update Nov 21 1.15pm: DOC has advised that due to weather the predator control operation planned for this weekend is cancelled.

Earlier:

The Department of Conservation (DOC) begins the first stage of its aerial predator control operation this weekend.

The non-toxic ‘pre-feed’ drop is scheduled for Saturday and Sunday (November 22–23), weather permitting, marking the start of DOC’s 37,000-hectare rat and stoat control programme across the Makarora, Young, Siberia, Wilkin and Cameron Valleys, as well as the Brewster Track.

Helicopters will distribute non-toxic cereal pellets over two days to familiarise pests with the bait before the toxic 1080 pellets are applied in one to six weeks’ time.

DOC says the operation is in response to a predicted beech mast this summer and rising rodent numbers, which pose a serious threat to vulnerable native wildlife, including the endangered mohua.

Several closures will be in place to ensure public safety while helicopters are operating.

The Blue Pools Track, Blue Pools carpark, Cameron Flat Campground and surrounding public conservation land will be closed from 8am Friday November 21 until Monday November 24.

Visitors are advised to avoid other parts of the treatment area during flight operations, and to check the DOC website or contact the DOC Wānaka Visitor Centre (03 443 7660) for updates or delays.

If poor weather affects the operation, work, and the associated closures, may be extended. 

This weekend’s operation uses only non-toxic pellets.
