Araucaria hunsteinii
Template:Short description Template:Speciesbox
Araucaria hunsteinii (Klinki, Klinkii or "Klinky", native names Rassu and Pai)Script error: No such module "Unsubst". is a species of Araucaria native to the mountains of Papua New Guinea. It is threatened by habitat loss.
Description
It is a very large evergreen tree (the tallest in New Guinea, and the tallest species in its family), growing to Script error: No such module "convert". tall, exceptionally to Script error: No such module "convert"., with a trunk up to Script error: No such module "convert". diameter. The branches are horizontal, produced in whorls of five or six. The leaves are spirally arranged, scale-like or awl-like, Script error: No such module "convert". long and Script error: No such module "convert". broad at the base, with a sharp tip; leaves on young trees are shorter (under Script error: No such module "convert".) and narrower (under Script error: No such module "convert".). It is usually monoecious with male and female cones on the same tree; the pollen cones are long and slender, up to Script error: No such module "convert". long and Script error: No such module "convert". broad; the seed cones are oval, up to Script error: No such module "convert". long and Script error: No such module "convert". broad. The seed cones disintegrate at maturity to release the numerous Script error: No such module "convert". long nut-like seeds.

Cultivation and usesScript error: No such module "anchor".
It is a fast-growing tree, and is being tested as a potentially important timber crop in tropical highland climates.
Pests
Barinae spp.,[Gray 1] Setomorpha rutella,[Gray 2] Microlepidopteras,[Gres. 1] Cacatua galerita (the Sulphur-crested cockatoo) are pests of pine nut production in A. hunsteinii. C. galerita may cause half of the seed crop to be lost in a year, mostly by trying to eat cones that are not yet ready.[Gres. 2] Another source describes A. hunsteinii as suffering few pests in plantations and therefore substituting A. cunninghamii in plantations with more pests.[1]

- The foraging activity of birds such as the Sulphur-Crested Cockatoo (Cacatua galerita) may lead to destruction of half or more of annual cone crops. Department of Forests (PNG) records suggest that over 50% of the A. hunsteinii cone crop in the Susu Mountain area, Bulolo was destroyed by cockatoos in successive years (1966 and 1967). Cacatua galerita is a notoriously wasteful eater and most seed is lost through the premature fall of green cones which are left to rot on the forest floor."
