Reversal in fortunes of rare kiwi species

Huge rowi return marks a reversal in fortunes of rare kiwi species

The rare rowi kiwi will reclaim valuable territory in north Ökärito forest in the largest ever release of the species by the Department of Conservation (DOC) to take place later this month.

Involving up to 36 birds, this release will see rowi chicks return to territory that the last kiwi retreated from over twenty years ago.

“This expansion of their home territory is a massive milestone for the critically endangered birds,” says Jim Livingstone, DOC Rowi Project Manager.

“Thanks to BNZ Operation Nest Egg, the department is increasing the species’ numbers pretty consistently, meaning we’re now in a position to help these birds claim back old habitats.”

“Things have been bleak for rowi. Birds were gradually pushed further and further south until they were backed up against the Waiho River—which they were unable to cross. It’s just good luck that they were left with a last section of forest to prevent the species from dying out completely,” he says.

Over the years rowi numbers have plummeted. Predators and loss of habitat mean they simply disappeared from many places and until they were reduced to just one population within 11,000 hectares in south Ökärito forest, north-west of Franz Josef. This month that trend will be reversed, as the first birds are introduced back into forest on the northern side of Ōkārito Lagoon.

“Rowi are a success story for kiwi conservation and provide a picture of hope for what we can achieve,” says Michelle Impey, Executive Director of the BNZ Save the Kiwi Trust.

“It’s extremely encouraging that, thanks to public support, we are able to witness a turn around in the fortunes of rowi.”

On Thursday 21 October 2010 these chicks will return home in a public ceremony after having been removed as eggs as part of BNZ Operation Nest Egg. They were hatched at Willowbank Wildlife Reserve in Christchurch and then raised on a predator-free island in the Marlborough Sounds. The young kiwi are now large enough to defend themselves (around 1 kg) against their main predators—stoats.

They will be closely monitored by DOC using cutting-edge tracking equipment, to see how they fare in this addition to their territory.
