|Mana Island is a DOC scientific reserve|
Mana Island is therefore ideal for projects that aim to save remnant or rare lizard populations. A translocation of Ngahere or bush geckos from a mainland quarry is a recent project. (Read more about the transfer of the geckos here.) I was part of a team of Friends of Mana Island volunteers which went over to monitor the Ngahere geckos and see how they are getting on in their new habitat.

Hands on with geckos
This is the second project I've worked on involving lizards. They are fun to work with because they are small and reasonably easy to handle. Although the first time I worked with them I was too hesitant handling them and got bitten quite a bit. Geckos look so soft and delicate you wouldn't realise they have such sharp needle-like teeth! I soon learned to be a bit more decisive! At the same time of course, you have to be gentle as these are protected species.

- Geckos and skinks are types of lizards.
- Along with tuatara, they are the only native reptiles that we have in New Zealand.
- Geckos have baggy looking skin and a distinct neck, but skinks are smooth and shiny and have no obvious neck.
- Reptiles are ectotherms which means they need an external heat source such as sunlight to warm them up.
- The green gecko is active during the day, whereas the various brown geckos are active at night.
A friend asked me why I was using the word 'translocation' to describe the Fairy Prion Project I volunteered on. 'Was it scientific jargon?' she asked. Why not say 'transfer' or even more simply 'move'?
I found the answer on the Department of Conservation website. 'Translocation' refers to the whole process which can involve several 'transfers'. The term also covers planning and monitoring. So the gecko monitoring work I did on Mana was part of the translocation process, although the geckos had already been transferred there.
