Cyclone Fehi hit New Zealand hard, but people weren’t the only ones who lost their homes. Chesterfield skinks lost over one third of their remaining one hectare home.

I recently visited the Shadehouse, a native plant nursery in Kerikeri, where I had the pleasure of meeting Roger a lizard enthusiast and member of Guardians of the Bay of Islands, a local group working on a diverse range of island restoration projects.
The Shadehouse nursery grows native plants for various community groups around the Bay of Islands. When the plants are ready at the nursery they are taken to whichever ecological district the seed came from and planted.

Potting mix which the Shadehouse uses on a regular basis has created the perfect breeding environment for rainbow skink, a pest species from Australia that competes with our native lizard species for food, habitat and space. Rainbow skinks are a threat to our invertebrates, ground nesting birds and other native lizard species. It also reproduces faster and in larger numbers than our native skinks.
Roger showed us various pit fall traps that he had set up around the Shadehouse as a biosecurity measure to trap these invasive pests.

The trap is made from a tin can placed inside of a hole with a piece of wood on top and is baited with cat food. The smooth tin walls make it difficult for rainbow skinks to escape but is friendly to our native species who are clever and can escape the traps.

The traps are checked on a regular basis and they are proving to be very effective at catching rainbow skinks.
If you wish to trap pest skinks seek some advice from your local DOC office to avoid accidental harm to our native species.

Thanks to Roger and the Shadehouse crew for a great day out in Kerikeri.
Naturalist, conservationist and herpetologist, Dylan van Winkel, has worked in an a variety of challenging environments, both in New Zealand and abroad. Today he writes about a recent visit to Hauturu/Little Barrier Island as part of a Pacific gecko translocation.
This post was originally published on Dylan’s blog.

Situated 15 miles from Cape Rodney, and 11 miles from Aotea/Great Barrier Island, Hauturu/Little Barrier Island bursts out of the ocean; its knife-edged ridges rising to 2,370 ft at the summit of Mount Hauturu.
The 3,038 hectare island is fringed by an almost continuous boulder beach—except where vertical cliffs plummet into the ocean.

It is a site steeped in rich Māori cultural tradition and nationally significant conservation initiatives; and is home to some of New Zealand’s rarest and most threatened fauna and flora.

The name Hauturu, was traditionally bestowed by Toi, who arrived in New Zealand from Hawaiki circa 1150 AD in search of his grandson Whatonga.
It was said that the island was uninhabited by “ordinary mankind” but on the misty summits lived the patu-pai-arehe/fairies, visiting the coastline only at night or in misty weather to fish and collect kai moana/sea food (Hamilton 1961).
While the thought of night-faring fairies is somewhat hard to believe, there is undoubtedly some truth in the myth, as at night, the island truly becomes alive!

Scaly creatures, spiny giants, venomous villains, feathery beasts, and slimy critters emerge and take over the forest floor. However, even so, walking at night requires cautious and vigilant steps, alerted senses, and often quick reactions to catch a glimpse of the island’s inhabitants.

By day, the island is alive with bird song and, in fact, Hauturu harbours the highest number of threatened bird species compared to any other island in the country! Their calls penetrate and echo through the 400-plus species of plants and, in particular, the dawn chorus is mind-blowing; arguably unmatched by any other site in New Zealand.

In January 2014, I was fortunate enough to join a team of conservationists, lead by Auckland Council ecologist Su Sinclair, on a lizard project, aimed at translocating Pacific geckos (Dactylocnemis pacificus) to two Hauraki Gulf Islands undergoing ecological restoration.
