Last weekend I volunteered with The Nina Valley Restoration Group. The group is lead by Hurunui College science teacher Tim Kelly, a young and enthusiastic teacher with a flare for inspiring excitement and motivation in his students. In conjunction with the Departmernt of Conservation their aim is to restore the Nina Valley, located in the Lewis Pass, to its pre-european biodiversity. This means controlling invasive mammals like Australian Possums, Stoats and Ferrets while facilitating recolonization of species like the Great Spotted Kiwi. Tim and the children at Hurunui College get to head up the majority of this project by setting traps, rescuing Kiwis, and reintroducing some from other areas. All of the Kiwi bird species are in decline and these efforts to save them from extinction have had great success though there is still a long way to go.
Kiwi has no wings, well it does have a couple vestigial nubs but they are unseen and unused. The Kakapo is a ground dwelling Parrot adapted to avoid arial predators but not mammals. The Tuatara is one of the worlds most ancient still-living reptiles with three eyes. All of these animals have suffered great losses since the introduction of mammals from mice to cats to deer to the most destructive; humans. They are unable to compete in this interrupted environment so we are trying to increase their chances.
On this trip we checked and baited a couple hundred ferret/stoat traps. They have caught many invasive mammals this way and the environment is improving noticeably.
We also retrieved audio recording devices being used to count the number of kiwis in the Nina Valley so that they have a better understanding of their restoration effort's effects. These devices were all located around 800-900 meters above the valley floor up densely vegetated slopes. It was not easy going and I can not express how impressed I am with the positive attitudes and enthusiasm coming from everyone involved.

It was quite exciting to find a male and female kiwi, both tagged and introduced to the valley, hiding together in the same burrow. This finding goes a long way to supporting the conclusion that the Nina Valley Restoration Group's efforts are making a difference and I am stoked to be helping them out.
