Cool, here's a link to the only araucaria we have in the US, at least that I'm aware of. Real buggers to work on...strange wood too, sappy stuff that can eat on you and your equipment. I've only wroked on a few, and removed one...it was no more than 22 inches dbh, and 50 feet tall, but made 12 yards of chips.

i'd love to hear more of the folklore about these tall trees. Robert Van Pelt, who scientifically measures big trees, has visited the euc forests, and, from his research, found no evidence or proof that eucs ever hit 400 feet....But, as fast as they grow, it sure wouldn't surprise me if they did..and I've heard stories of ones approaching 500 feet.
For that matter, he said there's no concrete proof that redwoods ever reached 400 feet, but I'll bet they did also. The tallest documented tree fell over in 1931. It was a douglas fir here in Washington, and measured 393 feet.
