Despite the heavy deforestation and clearance of native bush that took place during early settlement, a diverse range of wildlife and plant life populates the Port Hills. Native birds such as the bellbird ("korimako" or "koparara") fantail, silvereye, grey warbler and shining cuckoo are commonly found in the remaining bush. While the wood pigeon often seen in the area is a native to New Zealand others, such as the common blackbird, common chaffinch and song thrush are introduced and very populous species. As well as a great many insect species, gecko and skink are commonly found.
