The EPA, etc are huge >>and powerful. I work with a lot of companies, and some of them own land. Land with old growth forest, for example, which they happily log, even over the salmon steams which then become unusable for salmon. They buy the land for the trees, then take the trees, and if they can, turn the land into housing tracts. It's all about money, not about what is good in the long run. THAT is the problem, basically, with capitalism. It's about short-term profits, not long-term care. We saw it in the dot-com boom too. If all the companies thought long-term and for the good of humanity, there would not be a problem. But I'm old enough to remember WHY the EPA got formed, and it wasn't about gov't power. It was about unbreathable air. Shoot, I even remember having to fight to get seatbelts installed in cars. It was the same argument -- but a person who didn't want to go through the windsheild had to pay big bucks for the privalage of having seat belts. Until it became a law that cars had to have them. I'm not going to argue this any more -- I realize there are a lot of folks who are so adamantly in favor of " freedom " that they are willing to live with whatever the corporations do. There is likely a third alternative that doesn't involve big gov't or big corporations, but in the end we'll probably end up with the two merged: the corporation state, which is what Mussolini tried but failed to do. A lot of the complaints against " government " -- such as banning raw milk -- are not actually the government so much as corporations having undue influence and basically hijacking the political process. -- Heidi Quote Link to comment Share on other sites More sharing options...

If companies desire to turn land into housing tracts, of course they will clear cut it, but this has nothing to do with making money from the utterly unprofitable activity of clearcutting, but almost solely to do with the desire for housing land. Comapanies that desire to profit from the wood itself would never opt for clearcutting when there was another viable option, because they have to pay taxes on the dormant land while trees grow back. Foresters tell me it's like talking to a brick wall trying to get a company to opt for clearcutting, which is sometimes necessary due to diseases and whatnot. I personally believe there should be strict regulation barring the replacement of forest with monocrop cultures on public land, but the environmental movement's push for the banning of clearcutting on public land is outright stupid, and based on the idea that the forest will " self-regulate, " that human activity is an abberation from nature and even a curse upon it rather than part of it, when in fact the natural cycle of a forest is to kill itself over time.

It's > all about money, not about what is good in the long run. 250 million people all have a different opinion of what is " good in the long run " . I would never assume my opinion about what is good is right for everyone. But society needs to acheive a constant balance based on every changing information and opinions. Take development vs. preservation for example. Obviously American is not going to all forest or all developed land. But in a true free market, if people value virgin forest, as it disappears its price goes up. or, if more people begin to value it more because of chaning opinions the price goes up too, this is supply and demand. The more its value goes up the more it will be preserved, and the balance society wants is achieved. This is a far superior way for society to come to a balance than the political process, which will always serve the interests of rich corporations and special interest groups. from what I understand, most forest that is logged is owned or directly controlled by the government, not private. I know many private land owners who go through great efforts to responsibly log their land, because its in their best interest. And rivers as I mentioned have no defined property rights so its no surprise they get abused. Do you see that if that was my river, and I sold salmon from it, I am not going to let some logging company destroy it? Its now in someone's best interest to take care of it rather than hoping some politicians do it out of the goodness of their heart > But I'm old enough > to remember WHY the EPA got formed, and it wasn't > about gov't power. It was about un-breathable air. the point of my original post, the reason the air got un-breathable in the first place is because no one was taking care of it, it has no owner. and guess what, with the billion dollar epa the air is still un-breathable. and if the epa did make the air clean, they would all be out of jobs, its not in the best interest of the epa to actually take care of the air, just give the impression they are. I believe the exact opposite of what you think I think. government serves the interests of the most powerful in washington, aka corporations. The air, land, and oceans would be in much better shape if owners took care of them rather than corrupt politicians easily bought by corporations. > I'm not going to argue this any more -- I realize there > are a lot of folks who are so adamantly in favor > of " freedom " that they are willing to live with > whatever the corporations do. *sigh* i think such a statement shows you don't understand what I am saying. Then I shall not post anymore about this either. > A lot of the complaints against " government " > -- such as banning raw milk -- are not actually > the government so much as corporations having > undue influence and basically hijacking the > political process. why do corporations do this? because the government is the only group that has the legal power to FORCE people to do something. Now imagine that that kind of power did not exist? The point is without the government, corporations could never have forced pasteurized milk down our throats in the first place. There are always people who want to do bad things out of greed, why do we give them to tool to do it? Having a background in economics helped me understand these concepts which are not commonly known, but which I really believe to be true and in all our best interest. Heidi, I have the same goal as you. I am a birdwather, astronomer, camper, hiker, animal lover, old growth forest lovin guy. We just disagree, totally, on the best method to help protect that which we love. best regards, Joe Quote Link to comment Share on other sites More sharing options...

If it is *public* land, why clearcut it? Esp. the old forests? There are folks that go in and, say, take away some lumber, but frankly those old forests have done just fine for the last say, 2,000 years without clearcutting. Maybe a fire or two would help.

There should be *some* regulation on it, if it's public land, but an outright ban of clearcutting is rather silly, because sometimes clearcutting is best for management of the land, but otoh there are not the same profit motivations to prevent unnecessary clearcutting on public land so it would be equally ridiculous to simply let logging companies do whatever they want to the land. > The foresters I know like clearcutting because they can grow new crops, and > to some degree I agree.

I've only talked to a couple foresters, one was an environmentalist and one was a hardcore conservative, and neither of them were in favor of clearcutting in unnecessary circumstances.

If there was no profit motivation I wouldn't have a problem with it. The problem is that there are sweetheart deals and porkbarrel profits involved -- they don't clearcut the land that NEEDS it, often. I'd agree a wholesale ban on *anything* is usually a bad idea. Interesting. I've only talked to a couple foresters, one was an >environmentalist and one was a hardcore conservative, and neither of them were in favor of >clearcutting in unnecessary circumstances. Really? I wonder why it is so often done then. Around here they pretty much cut a quarter of a hill at a time, you can just watch, it's pretty ugly. I don't know that logging companies count as " foresters " though. Some folks I talked to from, say, Weyerhauser, were actually pretty far thinking. The loggers were more for short-term profits, but they do buy up big chunks of land for the trees. My point had to do with the fact that " land ownership " doesn't really solve the problem. It's a little like corporate raiders -- buy a company, take the savings, then dump the company. There is such pressure for short-term profits, there needs to be some counter-pressure for long-term care for the ecosystem. -- Heidi Quote Link to comment Share on other sites More sharing options...

Logging companies hire foresters to make complicated decisions about how to do the logging. They don't really need a forester to clear cut! Maybe they just want to develop the land? Or they don't own it? I don't understand why they'd clear cut (much less profit to tax ratio) if they weren't going to sell it, or use it for something more profitable.

The reasons I'd heard for clear cutting are that it's easier to get the trees out -- also most of the hill around here would be filled with the same size trees (it's mainly second growth) and they are all salable. On private property it's usually a mix of alder and evergreens, and they'd just take the evergreens, but I don't see many alder on the hills. Also they usually re-plant, and the young trees grow faster in a clearcut. -- Heidi Quote Link to comment Share on other sites More sharing options...

An extremely knowledgeable and experienced forester told me that the amount of wood you get over a given time with selective foresting is vastly higher than what you get for clearcutting, and logging companies prefer not to clearcut because that offers a quick boost of profit followed by a decade of paying property taxes with no revenue (for a given piece of land), rather than a slower but larger and continuous stream of profits. He said that more often than not he has a hard time " selling " a clearcutting recommendation when he believes it is necessary for the health of the land. He may have also added that inexperienced young and stupid people running some companies have the opposite preference and that their profits suffer because of it, but I had this rather extensive discussion several years ago so I can't recall perfectly.

If she's talking about what I think she's talking about, they own large tracts of land which they have on a thirty-year (I think) rotation. Each year they clear-cut a section and plant new trees.

Is the rate of growth of a tree somehow affected > by what other trees around it are doing? , At this point I'm no longer relying on my memory of my discussions with the forester but on my own speculation. Unless you're a woodchip company, it seems that big trees would have vastly more value than little trees. I'm not sure, but I'd think really big cuts would cost more beyond a certain point. But as a little thought experiment, say a tree grew an inch in diameter a year (for easy math). If boards less than six inches are relatively useless, It will be six years before you can even get *one* useful board out of a given tree. But after that point, not only do you get about one more board a year, but over time more of the area that would have gotten thrown off as slab, away from the middle, could be used for boards too. So I'd expect mature trees to accrue value much more quickly than young trees, so that one would maximize one's profit by cutting down only the biggest trees (or whatever other modifications manipulate the ecology in a way that makes the forest more productive, as decided by a forester.

Guest guest Posted November 8, 2003 Report Share Posted November 8, 2003 Chris- While your conclusion that older trees are more value on a per-year-of-age basis than younger trees may or may not be correct for some portion of the timeline, the basis of your thought experiment is flawed, because for a tree to continue to grow an inch in diameter per year (or in fact any constant annual amount) it would actually be growing much more with each passing year since each year's successive ring would be progressively bigger than the last's. >But after that point, not >only do you get about one more board a year, but over time more of >the area that would have gotten thrown off as slab, away from the >middle, could be used for boards too. - Quote Link to comment Share on other sites More sharing options...

I understand that, but the size and number of the trees that you can harvest is independent of your harvesting pattern given our current assumptions. Suppose, for example, that the optimum harvesting age of a tree is ten years, that you have enough land for a hundred trees, and that there are a hundred ten-year-old trees there. If you harvest a hundred trees every ten years, you'll be able to harvest six hundred trees in fifty years (and have no trees at the end). If, instead, you harvest ten trees every year, you'll be able to harvest five hundred ten trees in fifty years (although these will be bigger, because some of the ones harvested in the first ten years were older than ten years old), with ninety trees remaining, ranging from one to ten years old. Of course, the trees in a given area are probably going to be of varying ages, so there's an initial inefficiency to clear-cutting (and, as you mentioned, possibly some negative tax implications), but this becomes less significant in the long run. For staggered harvesting to have any significant long-run advantage over clear-cutting (ignoring tax issues, because I prefer to deal with things that make sense), it would have to make trees grow faster somehow, I think. -- Berg bberg@...

You're right in terms of tree farms I think. I was thinking of pre- existing forests. I guess I don't know why it would be disadvantage then. I can't continue to support the idea, as I'm just passing along someone else's thoughts, which I assumed were reasonable given his experience.

Just think of a piece of paper with a set of concentric circles drawn where each successive circle has a diameter 1 " larger than the previous one. Each successive circle will form a donut between its edge and the edge of the next circle in, and every donut will be half an inch wide. Therefore, each successive donut (or ring, if you're looking at the graph as a cross section of a tree) will cover substantially more surface area on the page than the last. IOW, for a tree's diameter to grow at a constant rate, its actual growth (the surface area of each concentric ring (and therefore the volume of each concentric layer of the tree) would have to accelerate.

Actually I'm not sure it's the same amount of wood even that is added per year ... The trees grow a LOT in the first few years, and less and less as they get bigger. The really old trees and a tiny bit of diameter each year. They don't grow much taller either. It's kind of like cows and other animals: they do this growth spurt, then they settle down to more or less one size. From a financial point of view, there is an optimum harvesting size. I think for Fir it's 40 years or so. They do get huge after a few hundred years, but the logging companies don't wait that long. There is also the issue of sunlight and competition. Evergreens create a " dead zone " underneath them where nothing can grow, esp. the old ones. There is no sun, and a thick layer of needles that are toxic to most plants and don't hold water. So if you are replanting, you need to have " thin " spots where the seedlings can take hold. In the newer forests, you have a mix of trees, undergrowth, and grass. In the old forests, you have wall to wall big trees. I wonder if this has something to do with the fire issues too. The old growth forests have less undergrowth, and many species of big trees are pretty fireproof themselves. But the younger forests burn a lot easier. The Indians used to do a fair bit of burning to clear undergrowth (to encourage deer and make them easier to travel through) which probably kept the major fire hazards down. -- Heidi Quote Link to comment Share on other sites More sharing options...

Am I correct in assuming the growth occurs by mitosis? This may be way off and I don't know any more about botany than I do about forestry, but assuming the cells are mitotically reproducing, each time there are twice as many cells to reproduce, so the growth rate should be exponential and not linear in terms of volume.

Heidi, You seem to be making my point rather than 's here though, considering 40 years is an awful long time. If profit is maximized by harvesting 40 year old trees, than you would make a lot more money over 20 years if you cut down only the trees that offer peak profits each year, no?

Right but in that case they're really in the development rather than lumber business in terms of practical applications. But I've given up arguing that point because the fact is I don't know squat about forestry, and obviously if some companies are tree farming than not all companies reject clearcutting as a sustainable lumbering practice. But now I'm just trying to discuss from a purely theoretical standpoint what is most profitable, which is what the post of 's that you responded to was responding to. > (And I know someone is going to say we'll run out of straw, > but currently it is being burned off in some places, it's > a waste product mostly). Well when the time comes we can just start using marshmallows. Chris Quote Link to comment Share on other sites More sharing options...

I wasn't assuming that-- the trachea cells are dead and function to transport water, I know that at least-- but the outermost shell is the only part relevant to my point.

There would be more cells regardless of thickness each time, because if each cell reproduces once, each successive generation of cells contain twice as many cells. There's a growth spurt, but > eventually the rings get awfully thin.

That's what Heidi was just saying, but how long does the growth spurt last? If 40 years is a decent average, than it seems that that while not " indefinite " is long enough that my point was valid.
