Survivor! The tree that survived the dinosaurs!
The Wollemi Pine.
In lieu of an abstract, here is a brief excerpt of the content:
David Noble, Tony Zimmerman and Michael Casteleyn enjoy canyoning and find the rugged Wollemi Wilderness particularly challenging. It is a magnificent place; an ancient landscape with extraordinarily diverse features, from its deep narrow canyons and pagoda-like formations, to its many limestone caves. It is part of the one-million-hectare Greater Blue Mountains World Heritage Area. The uplift of these rugged hills and the beginning of their slow dissection began some 60 to 90 million years ago. This uplift has slowly worn away since then to form plateaus criss-crossed with many hundreds of narrow canyons carved through the sandstone massif. The landscape diversity that has formed from this erosion has resulted in a large range of ecological niches; from bright, warm and dry plateaus with the characteristic blue tinge of eucalypts, to a cool, damp rainforest environment at the base of steep and narrow canyons.
