On Monday April 8, Dr Graham Ussher and his team from RMA Ecology will be safely capturing Waitaha geckos from the Gollans Bay quarry to be released in Riccarton Bush on Tuesday afternoon April 9.
The eastern part of the Gollans Bay quarry has not been quarried before and is being used as part of the Lyttelton Port Company’s (LPC) Te Awaparahi Bay Reclamation project, creating a new container terminal to keep up with shipping demands.
Some of the area is habitat for New Zealand native Waitaha gecko, and LPC recently gained a Wildlife permit from DOC which sets out how the company must manage the effects on geckos.
Dr Ussher says the Waitaha are a small, nocturnal native gecko special to the central and southern South Island.
DOC regards the Waitaha geckos as a species that has reduced in numbers and distribution since the arrival of people and pest animals. They can live to be over 36 years old.
“That is why LPC is doing its best to capture and relocate the geckos to a safe place before the quarry is developed,” says Dr Ussher.
Last week Dr Ussher and LPC workers placed artificial habitats at key locations around the quarry to safely capture the geckos.
The team is aiming to catch all the geckos within the salvage area, which will include young lizards as well as adults which could be over 20 years old. The geckos will be released into tall native forest at Riccarton Bush.
“Although Riccarton Bush is different to the habitat from which they will be captured, we expect that they will do just fine – they are hard wired to use a range of habitats,” says Dr Ussher. “We are confident they will enjoy their new lodgings.”
Riccarton Bush was chosen because it has 7.8 hectares of established forest surrounded by a state-of-the-art pest and mammal-proof fence that keeps out predators such as rats and cats.
Before the arrival of humans, geckos would have been abundant and lived in a range of habitats from the sea shore to the forest canopy.
DOC’s Community Ranger Rachel Brown says a similar release of geckos was done in 2012 as part of the Sumner Road recovery project.
“Those geckos have been regularly seen by visitors and the Riccarton Bush Trust Ranger, so it's fantastic to see more of these native creatures safely relocated.”
All New Zealand geckos are fully protected, meaning they may only be handled under permit. It is illegal to deliberately harm them.
Ngāti Wheke are supporting the relocation of the geckos and will be attending the release to perform a karakia.
Reporters are welcome to attend the release of the geckos on Tuesday, April 9 at Riccarton Bush. We will be meeting ay 1.30 pm at Riccarton House for the release at 2 pm.
