It is not known whether currently exists the tallest araucarias in Bulolo Valley including 88.9 m tall (or taller) Klinki pine – but it existed in 1941. Back then such a tree was measured and later mentioned in a classical ecology book by Paul W.Richards "The Tropical Rain Forest: An Ecological Study" which was issued in 1952.

Since then the fact that such tall araucarias might exist in Papua New Guinea has been repeated in many scientific works, notably in the article by Gray B. (Size composition and regeneration of Araucaria stands in New Guinea) in 1975.

There is little doubt that klinki pine is the tallest of all araucarias. This tree grows in Madang, Morobe and Eastern Highlands Provinces of Papua New Guinea, in mountainsides and ridges.

The wood of klinki has outstanding qualities and this beautiful araucaria is widely exploited, it is cut also by slash&burn agriculture. As a result, this tree is becoming rarer and nowadays natural stands can be found in more remote areas.

These trees are very impressive. The average diameter of klinki in old-growth stands is 200 cm and more! Trees in such stand are at least 55 m tall, often exceeding 70 m height.

The fantastic 88.9 m tree was measured near Bulolo. Currently in Bulolo has been established an important forestry industry with large plantations of klinki pine. Happily, natural stands of this tree are not too rare.

Wondermondo has marked a beautiful stand of klinki pine in Wau Gorge some 15 km from Bulolo. No one knows whether here are tallest araucarias which are up to 90 m tall – but it is definitely worth to check it out!

One of the most exciting and mysterious lands in the world is Papua New Guinea. This country takes half of the second largest island and numerous other larger and smaller islands. Up to this day Papua New Guinea is poorly investigated and here are expected numerous exciting discoveries of geological, biological and archaeological nature.

Category includes some of the most impressive and interesting separate trees of the the world. Total number of tree species in the world still is a wild guess – may be 10,000 and may be 100,000 but most likely somewhere in between. Every month there are reported new tree species from the whole world, including the Western Europe.
