Here's a story. A bit embarrassing, maybe, but how do we ever learn except by making foolish mistakes?
It was the late 1970s. I had been away from the coastal rainforests for 20-some years, ever since my teens. And now here I was in the north country, with a house and small farm. I had a lot to learn.
How to stay warm in the winter, for example. That first year, I made sure the woodshed was full. Three cords worth (about 11 cubic metres), they told me, would last a winter. We cut trees on our property, hauled them down the hill, chain-sawed and chopped them into stove-sized chunks, stacked them neatly. The woodshed, piled up to the roof, smelled of freshly-cut wood. It felt so good!
We had red alder, pines and fir on our side hill, and cottonwood. The cottonwood was bigger, and we ended up with a good stack of it.
("Cottonwood burns well", says a Canadian government page. Some conditions apply.)
Cottonwood is a tree that grows in moist to wet to very wet conditions. It "acts as a massive nutrient pump, drawing up and storing nutrient-rich water." (Vancouver Island Big Trees) Ours was typical. We found out the hard way. In mid-winter, with the temperature hovering around 20 below zero Celsius, and our airtight stove roaring away, we were cozy enough. Unless we were trying to burn that fall's cottonwood. Inside the stove, it oozed and steamed and dripped, and put out the fire. In the woodbox beside the stove, it made puddles on the floor as it thawed out. I took to putting a few pieces at a time on top of the stove to dry out; there it hissed and whistled as the steam found its way out. Only when it stopped dripping did I dare put it into the fire. Then, yes, it did burn well. But it didn't produce much heat. Or hold a fire overnight.
Live and learn.
But I do still love cottonwood. Not in a stove, but standing tall, glowing in the fall light, growing lichens and mosses all year; the rough bark, the scarring, the tangled and broken branches all up and down the trunk, and maybe also the dampness of the wood even in summer, provides a rich habitat.
These three lichens are on cottonwoods at Oyster Bay.

- Unos líquenes polvorientos en la base de un tronco.
- Un liquen de hoja despegada, grande. Tal vez sea una pulmonaria, o algo parecido.

I'm having to moderate all comments because Blogger seems to have a problem notifying me. Sorry about that. I will review them several times daily, though, until this issue is fixed.
Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
