I'm guessing you're thinking of a collection of trees,

with their rugged stems and their beautiful crowns.

Yes, trees are the foundation of forests,

but a forest is much more than what you see,

and today I want to change the way you think about forests.

You see, underground there is this other world,

that connect trees and allow them to communicate

and allow the forest to behave as though it's a single organism.

It might remind you of a sort of intelligence.

I grew up in the forests of British Columbia.

I used to lay on the forest floor and stare up at the tree crowns.

and he used to selectively cut cedar poles from the inland rainforest.

Grandpa taught me about the quiet and cohesive ways of the woods,

He and I had this curiosity about forests,

Our poor dog Jigs had slipped and fallen into the pit.

So grandpa ran up with his shovel to rescue the poor dog.

But as grandpa dug through that forest floor,

and under that, what I learned later was the white mycelium

and under that the red and yellow mineral horizons.

Eventually, grandpa and I rescued the poor dog,

but it was at that moment that I realized

But soon I found myself working alongside the powerful people

and I soon found myself conflicted by my part in it.

Not only that, the spraying and hacking of the aspens and birches

to make way for the more commercially valuable planted pines and firs

It seemed that nothing could stop this relentless industrial machine.

You see, scientists had just discovered in the laboratory in vitro

could transmit carbon to another pine seedling root.

and I wondered, could this happen in real forests?

Trees in real forests might also share information below ground.

and I had a really hard time getting research funding.

and I eventually conducted some experiments deep in the forest,

paper birch, Douglas fir, and western red cedar.

I figured the birch and the fir would be connected in a belowground web,

and I had no money, so I had to do it on the cheap.

and I bought some plastic bags and duct tape and shade cloth,

And then I borrowed some high-tech stuff from my university:

a Geiger counter, a scintillation counter, a mass spectrometer, microscopes.

And then I got some really dangerous stuff:

syringes full of radioactive carbon-14 carbon dioxide gas

of the stable isotope carbon-13 carbon dioxide gas.

the bear spray, the filters for my respirator.

The first day of the experiment, we got out to our plot

and a grizzly bear and her cub chased us off.

But you know, this is how forest research in Canada goes.
