$this->bbcode_second_pass_quote('careinke', '')$this->bbcode_second_pass_quote('Revi', 'I') think a half a cord per acre is the amount that a northern forest grows.
Wow, just my big leaf maples put out more than that.
That would be some tree. Lets simplify it and run some numbers. Lets make our simple tree three feet in diameter and eighty feet tall and assume the top if you added it all up would match the taper of a tree. So we have a simple cylinder to compute. Now a good growth rate for a maple is a quarter inch growth ring per year but your in a rain forest so lets compute a half inch thick layer of growth. you get .04 ft( a half inch) times pi. 3.14 to get the circumference of the tree times 3ft times 80 ft. divided by 128.
.04x3.14159x3x80/128 =0.2356 cord
So you need five tress this size to get a cord in a years growth but fortunately more then five large trees live on an acre.If each tree occupied a thirty foot diameter circle you'd have about 62 per acre.

I was not talking about just one tree, I was talking per acre. Anyway, I'll have to get a picture of our maples, not anything like Pops. It grows in clumps and look like something from Avatar, including full size ferns growing on them fifty feet in the air.

$this->bbcode_second_pass_quote('pstarr', 'N')ot trying to show off (much
) careinke but I've cut larger redwood saplings.
$this->bbcode_second_pass_quote('wiki', 'G')rowth of seedlings is very fast, with young trees known to reach 20 m (65 ft) tall in 20 years.
Don't have many redwoods out here.
I have ground I grew corn on twenty five years ago that now has trees sixty feet tall on it. But those are the fast growing emergent species poplar and white birch etc. Not very useful.

OK, first off I said Pops and of course I meant Revi. I wish my maples were like his, I actually tried tapping these, but the sapp does not work the same here with this type of maple and I got nothing. I understand that someone is tapping maples on Vancouver Island but it must be another type of maple.
After considering everyones comments on amount of wood produced per acre, I need to re-look at our production. I am thinking I must have over estimated it. I do know we pull at least 3 cord a year off of our 32 acres with the forest mass still building. We get this wood from wind felled trees exclusively.
I am looking at adding redwood to our forest. The predicted climate shift here would make redwood a good species to eventually replace what I expect to eventually be a die off of Cedar and Doug fir. I'm in discussion with the FSC folks to see if it would fall within their standards.
Here is a pic of a couple of my maples (and my son and DIL). You can see the one on the right has multiple trunks (typical). I'll see if I can find a better picture.

$this->bbcode_second_pass_quote('pstarr', 'G')orgeous picture. It seems Redwood thrives in summer fog and warm wet winters. Along the coast here Doug Fir grows at higher elevation, where there is more summer heat. How does that fit where you are?
Well the summer fog could be a problem. I am searching for something that likes warmer wet winters and warmer dry summers. I was thinking, since redwood is south of us and the few redwoods I've seen planted around here grow very fast and vigorously, they might be an option. Cedars (our climax species) around here, have not fared too well lately. This is not limited to my property, but all around the area. I think the recent summer droughts are taking their toll.
As far as Doug fir, there is a pretty nasty beetle on its way. Which I guess shows that monoculture, even in forests, may not be the best option.

$this->bbcode_second_pass_quote('pstarr', '')$this->bbcode_second_pass_quote('vtsnowedin', '')$this->bbcode_second_pass_quote('pstarr', 'S')nowy good advice. 500 years of clearcuts, sheep, and erosion are bound to unsettle an ecosystem.
Fact check Pstarr. :
The town was settled in 1794. That is just 221 years ago. Not that clear cuts, sheep and dairy cattle didn't do real damage in those 221 years.
Who knows how long the native americans were burning/managing the forests for acorn/deer production.
Nobody considering that oaks don't grow here.
There has been only one arrow head found in the town limits. Apparently the Natives passed it by on a regular basis heading towards the salmon in the Connecticut river and the corn that could be raised in the fields beside it.
