Battle for our Birds operation underway in Waikaia
The Department of Conservation’s Battle for our Birds pest control operation in the Waikaia Forest begins today.
The Waikaia operation in northern Southland is one of 22 confirmed operations that will use aerially applied 1080 over
about 600,000 hectares of conservation land to knock down rising predator numbers fuelled by unusually heavy seeding in
South Island beech forests.
The coordinated Battle for our Birds pest control programme is targeted to protect the most at-risk populations of
mōhua/yellowhead, kākāriki/parakeet, kiwi, whio/blue duck, kea, kākā, rock wren, giant land snails and native bats at
sites across the South Island.
The Waikaia operation will protect threatened mōhua populations along with long-tailed bats/pekapeka, robins/kakaruai,
yellow-crowned parakeet/kākāriki, hectors tree daisy, large land snails and peripatis/velvet worms over just under 7000
hectares in the forest.
DOC Catlins services ranger Cheryl Pullar said monitoring results show significant silver beech seed-fall in the area
and rapidly rising rat and mice numbers.
“Rodent numbers are already tracking towards levels that will trigger a stoat plague in the next few months—just as our
most vulnerable species are nesting and trying to raise their young.
“If we don’t act now to knock back these predators, we could lose species such as mōhua and long-tailed bat from
Waikaia.”
Today non-toxic cereal pellets laced will be applied to the treatment area, which encourages the pests to more readily
eat the pellets. The toxic pellets, laced with the biodegradable poison 1080, will be spread across the target area
during the next spell of clear weather.
Planning for about 30 Battle for our Birds pest control operations covering about 700,000 hectares of public
conservation land, mostly in the South Island, has been underway since January following the prediction of a once in
15-20 year beech seeding event.
A close watch is being kept on six other target beech forest areas in South Westland, Southland and Fiordland to see
whether rodent thresholds are also reached over the coming months and a pest control response is also required.
