The environment of New Zealand is characterised by an endemic flora and fauna which has evolved in near isolation from the rest of the world. [1] The main islands of New Zealand span two biomes , temperate and subtropical , complicated by large mountainous areas above the tree line. [ 2 ]

The kiwi is a national symbol of New Zealand. The animals of New Zealand, part of its biota, have an unusual history because, before the arrival of humans, less than 900 years ago, the country was mostly free of mammals, except those that could swim there (seals, sea lions, and, off-shore, whales and dolphins) or fly there .
The introduction of many invasive species is threatening the indigenous biodiversity, since the geographical isolation of New Zealand led to the evolution of plants and animals that did not have traits to protect against predation. New Zealand has a high proportion of endemic species, so pest control is generally regarded as a high priority.
The fruit contains a special fleshy structure called a receptacle which helps attract birds such as the kererū, tūī, and bellbird, who then eat the fruit and disperse the seed elsewhere. One 2008 study in the New Zealand Journal of Ecology found a mean retention time of kahikatea seeds in kererū of 44.5 minutes. [20]
Many of New Zealand's bird species are endemic to the country, that is, they are not found in any other country. Of the species breeding in New Zealand before humans arrived, 71% were endemic. [1] Some species are not fully endemic, but are breeding endemic, in that they breed only in New Zealand, but migrate or range elsewhere.

From the time of first human settlement until 1994, 43 (or 46%) of the 93 endemic land, freshwater and coastal bird species have become extinct, as have 4 of the 22 endemic seabird species (making 41% of all endemic species extinct), according to a 1997 report.
