I'll bet you told her all your trees were sequoias.

They stop before a redwood trunk marked with historical dates.

To us, when we look at a Redwood tree, it seems to be motionless and still, and yet Redwoods are constantly in motion, moving upward into space, articulating themselves and filling Redwood space over Redwood time, over thousands of years.

A Redwood is a fractal. And as they put out limbs, the limbs burst into small trees, copies of the Redwood.

What can the Redwoods tell us about ourselves?

Steve Sillett, when he was a 19 year old college student at Reed College, had heard that the Redwood forest canopy is considered to be a so called Redwood desert.

And yet, when you look at the base of a Redwood tree, you're not seeing the organism.

Think about this tree, rising upward into Redwood space, 325 feet, 32 stories, an individual living organism articulating its forms upward into space over long periods of time.

That tree...!

We're looking at the very top of Gaya, which is thought to be the oldest Redwood.

That is to say, at that time it was believed that there was nothing up there except the branches of Redwood trees.

The Eastern Hemlock tree has often been described as the Redwood of the East.

Redwood rainforest is incredibly difficult to move through, and even today, individual trees are being discovered that have never been seen before, including, in the summer of 2006, Hyperion, the world's tallest tree.

Redwoods have an enormous surface area that extends upward into space because they have a propensity to do something called reiteration.

This is the realm of the Coast Redwood tree.

Redwoods grow very slowly in their tops.

Ants are not known to occur in Redwood trees, curiously enough, and we wondered whether this ant, this species of ant, was only endemic to that one tree, or possibly to that grove.

And then it bursts into a forest of Redwoods.

He climbed up a small tree next to this giant Redwood, and then he leaped through space and grabbed a branch with his hands, and ended up hanging, like catching a bar of a trapeze.

Redwoods grow back into themselves as they expand into space, and this flying buttress is a limb shot out of that small trunk, going back into the main trunk and fusing with it.

These are Serphas lighting juniper branches.

We have fir trees, the forests are tightly packed

The blue whale, it's a dwarf if compared with the real biggest creature that exists on the planet that is, this wonderful, magnificent Sequoiadendron giganteum.

If a portion of a Redwood is rotting, the Redwood will send roots into its own form and draw nutrients out of itself as it falls apart.

You can see the range of the Coast Redwoods. It's here, in red.

The tree leaves turned red.

They're finding out that Redwoods can move moisture out of the air and down into their trunks, possibly all the way into their root systems.

They believe juniper smoke is holy.

The Redwood species seems to exist in another kind of time not human time, but what we might call Redwood time.

There are two people climbing this tree, Gaya, which is thought to be one of the oldest Redwoods. There they are.

And this is a living organism that has a mass of at least 2,000 tons.

Search again in the shrubs and there under the fir.

When Steve Sillett gets up into a big Redwood, he fires an arrow, which trails a fishing line, which gets over a branch in the tree, and then you ascend up a rope which has been dragged into the tree by the line.

But it's believed that the oldest living Redwoods are perhaps 2,500 years old roughly the age of the Parthenon although it's also suspected that there may be individual trees that are older than that.

What they're doing in the Redwood forest canopy soil hundreds of feet above the ocean, or how they got there, is completely unknown.

Redwood time moves at a more stately pace than human time.

This is the spruce Gran Picea, which at 9,550 years is a mere babe in the woods.

Steve Sillett and Marie Antoine are the principal explorers of the Redwood forest canopy. They're world class athletes, and they also are world class forest ecology scientists.

We have now discovered that there is a multi directional transfer of nutrients between plants, mitigated by the mcyelium so the mycelium is the mother that is giving nutrients from alder and birch trees to hemlocks, cedars and Douglas firs.

And maybe about here, about 30 feet, is the diameter of a big Redwood.

Nobody knows how old the oldest living Coast Redwoods are because nobody has ever drilled into any of them to count their annual growth rings, and, in any case, the centers of the oldest individuals appear to be hollow.

But curiously, Redwood rainforests, the fragments that we have left, to this day remain under explored.

The mangroves are being cut down the effects of things like the tsunami get worse.

The leaves of the trees in the garden have turned completely red.
