Ōtari-Wilton's Bush is a native botanic garden and forest reserve located in Wilton in Wellington, New Zealand.

Otari-Wilton's Bush is a public botanic garden dedicated solely to New Zealand native plants.

[4] There is a path suitable for wheelchairs from Wilton Road to the Visitor Centre, and from there to the Cockayne Lookout via the Canopy Walkway.

Large trees in the wider area were felled for timber when European settlers arrived in the region, and farms were established.

[5] In 1860, a far-sighted local farmer named Job Wilton fenced off 7 hectares (17 acres) of original forest to protect it from stock.

[8] In 1918, the land was transferred to Wellington City Council for “recreation purposes and for the preservation of native flora”.

Major losses are blamed on industries such as agriculture and forestry, and the introduction of animal pests and invasive weeds.

The Native Botanic Gardens at Otari-Wilton's Bush include many New Zealand plants that are threatened in the wild.

Climbing plants are also common throughout, including supplejack, New Zealand passionfruit, and several species of rata (metrosideros).

On the upper slopes, the predominant trees are māhoe, rewarewa, tawa and kohekohe, with some forest remnants of matai and rimu.

In damp areas, there are pukatea that typically have large plank buttress roots to support their growth.

[16] Birds seen (and/or heard) at Ōtari-Wilton's Bush include kererū, tūī, kingfisher (Māori: kōtare), fantail (pīwakawaka), grey warbler (riroriro), silvereye (tauhou) and morepork (ruru).

The trust deed registered with the application describes the principal purpose of the trust as: "To educate the local and wider community in New Zealand flora, thereby fostering public awareness and appreciation of native plants and of the environmental importance of their protection, conservation and rehabilitation and promoting the unique botanic diversity of Otari-Wilton’s Bush".
