The Sinbad Gully is an area of significant conservation interest. It has been home to some of the most unique ecosystems in the world, largely untouched for millions of years. Today it continues to house a wide variety of native species and unique flora and fauna, such as the Sinbad skink, and is home to a wide range of native birds including rifleman, weka, kaka, kiwi, whio, bellbird and tui. Located at the base of the iconic Mitre Peak/Rahotu, near the head of Milford Sound/Piopiotahi within Fiordland National Park, it is also part of World Heritage Area, Te Wāhipounamu.

The Sinbad Gully has been greatly affected by introduced pests, however, unlike other areas that have been completely decimated, it has managed to maintain populations of many native species. The most likely reason being that the very steep terrain and tough climate have acted as buffers from complete dominance by pests such as rats, stoats, possums and deer. This was perhaps also why it was one of the last places that kākāpō were found in Fiordland.

Importantly, it means the Sinbad Gully still has a chance of being an oasis of some of Aotearoa New Zealand’s most treasured species.

Following the stepping back of a company's support in the Gully, a private donor has come forward to help ensure this valley's native species are protected and predators are kept at bay. The project works closely with the Department of Conservation and there is much to be done to ensure this area is not only protected but gets the opportunity to flourish once again.
