Distribution

The tree is native to the North Island from south of 35°S and from Cape Farewell to Whanganui Inlet area and locally at the north end of the South Island, near Nelson (41° S).[2]

It grows from sea level up to 600 metres (2,000 ft) in altitude, in temperate rainforests.

It is an IUCN Red List Near threatened species, that is endangered by habitat loss.[3][1]

Description

Libocedrus plumosa is an evergreen coniferous tree growing to 30–35 metres (98–115 ft) tall, with a trunk up to 3 metres (9.8 ft) diameter. The bark is loose, fibrous and light brown.[2]

The foliage is arranged in flattened sprays; the leaves are scale-like, arranged in opposite decussate pairs on the shoots; the facial leaves are 1–2 mm long and 1 mm broad, and the lateral leaves distinctly larger, 2–5 mm long and 1.5–2 mm broad.

The seed cones are cylindrical, 12–18 mm long, with four scales each with a prominent curved spine-like bract; they are arranged in two opposite decussate pairs around a small central columella; the outer pair of scales is small and sterile, the inner pair large, each bearing two winged seeds. They are mature about six to eight months after pollination. The pollen cones are 3–5 mm long.[3]

Cultivation

The kawaka has been planted as an ornamental tree in several parts of the British Isles, including as far north as Castlewellan, Northern Ireland.[4]

[de] Libocedrus plumosa

Libocedrus plumosa oder Kawaka[1] ist ein immergrüner Nadelbaum aus der Gattung der Schuppenzedern (Libocedrus). Das Verbreitungsgebiet der Art liegt auf der Nord- und Südinsel von Neuseeland. Dort wächst sie im Tiefland in immergrünen Regenwäldern mit hohen Jahresniederschlägen, warmen Sommern und milden Wintern. Das dunkle, rötliche Holz ist für Täfelungen und Furniere beliebt, doch hat die Art durch ihre Seltenheit und den Schutz nur geringe wirtschaftliche Bedeutung. Sie wird auch nur selten als Zierpflanze verwendet.
