|The project began for the protection of breeding sites of pelagic bird species such as the endemic white-flippered little blue penguin, the only titi (sooty shearwater) colony in Canterbury, and yellow-eyed penguin at their northern breeding range. The Wildside has also been recognised internationally in the IUCN Invertebrate Red Data Book (1983) for a place of high invertebrate endemism. Other iconic and threatened species outcomes include the protection of jewelled gecko, spotted skink, the Banks Peninsula tree weta and Akaroa daisy (both found only on the Wildside).
The Wildside is a nationally significant area for the protection of sea bird breeding sites as it bounds the only two marine reserves on the east coast of the South Island, Pohatu and the Akaroa Marine Reserves. With the largest penguin colony on mainland New Zealand at Flea Bay.
The Wildside covers 13,500ha and focuses on habitat protection, with 25% of the Wildside held in private or public reserve, and predator control, with over 700 predator traps controlling feral cats, ferrets, stoats, weasels, and possums used in this extensive trapping programme.
