Mountain searchers strike lizard gold

‘‘There is much about our alpine lizards still be discovered.’’ Dr Jo Monks, Department of Conservati­on science advisor

Scientists who unearthed a population of rare Cupola geckos in Nelson Lakes National Park may have also discovered an entirely new gecko species.

It is among several geckos and skinks found during surveys in remote South Island mountains that are either new population­s of known species or completely new species.

Department of Conservati­on science advisor and lizard survey project leader Dr Jo Monks said field teams ‘‘struck gold’’ when they found previously unknown skinks in Fiordland and on the West Coast, along with geckos in the Nelson Lakes and Mt Aspiring national parks during recent surveys.

‘‘They look different to known species, but we won’t know for certain until we get the results of genetic testing.

‘‘If they aren’t new species, it means we have discovered population­s of these lizards in places we didn’t know they were, which is great news.’’

The DOC-led survey teams spent about three days at each site searching for lizards, combing the ground, carefully lifting rocks and

spotlighti­ng at night for geckos, which are nocturnal.

The surveys sought to gain more informatio­n about poorly known or ‘‘data deficient’’ lizards, some of which had only been seen once or twice previously.

In the Wick Mountains in northern Fiordland, 20 skinks were found in an area that hadn’t been previously surveyed but was thought to be suitable lizard habitat.

A trip near Mt Alba in Mt Aspiring National Park to investigat­e

a single gecko sighting resulted in nine geckos being found in an area far from other known population­s.

Lizard prints in a rodent tracking tunnel in the Hooker/ Landsborou­gh Wilderness Area on the West Coast also sparked a threeday search that led to the discovery of a pregnant female skink.

Another gecko was found in Nelson Lakes National Park, on the same trip where the elusive Cupola gecko was also rediscover­ed this summer after only two previous sightings.

‘‘These finds are very exciting, and show there is much about our alpine lizards still be discovered,’’ Monks said.

Aotearoa has more than 110 lizard species (geckos and skinks), many of which are endemic. Their ecology is poorly understood, and scientists are currently aware of about 33 alpine species.

DOC is awaiting results of genetic testing to identify the specimens found and confirm whether they are new species.

There have been five lizard species newly discovered in the past few years, including in north Otago and northwest Nelson, in Kahurangi National Park.

DOC is keen to hear from the public about lizard sightings, which could lead to new findings. People are asked to take photos of lizards and send a report with the exact location informatio­n to lizard research@doc.govt.nz.
