Been several discussions on this over the years, so I thought I'd open the can of worms again.  ;D

Tree diameter is based mostly on the growing space the tree has had throughout its life,and only loosely on its age. Just because a tree is twice the diameter of another a few feet away doesn't mean that the large tree is twice as old.  It means that the large tree had more growing space, and thus outgrew its neighbors in the same amount of time.  Whoever gets the most sunlight wins.



Tree on the left is a white oak, greatly suppressed throughout its young life. In fact, it is already developing a hole in the middle and mineral stain from poor soil and extreme competition. It was on the edge of a pocket of thick saplings within a mature forest.  Tree on the right is a loblolly pine, plantation grown on good soils, planted at a proper spacing. It was cut during the first commercial thinning operation to give its better quality neighbors even more growing space so they would grow faster.

Both trees were 23 years old when cut.

I remember sawing that log on the left.  It had much stress and had to be flipped 180° after each pass.   :-\

Seriously, fast growing trees like that can cause heartburn when you are sawing.  They also produce very low quality lumber.

This board is from a self seeded backyard eucalyptus tree I removed for a friend. Hard to see the growth rings, but it was about 10 years old. I didn't expect it to be of any use, and just free handed a couple of slabs of it to see what would happen. I actually dried perfectly.  :o I just put it under the mill to true it up after it had dried.  This is a hardwood, comparable to oak, that's grown that fast.


Found this old pic of the stump. That's a 28" bar on the Dolmar.


Then there is my Rimu tree down in the back garden.
Also 10 years old, and about 2" DBH.  :D

This is actually pretty good growth for a rimu. Give it another 190 years and it might amount to something  :D

This is always an interesting topic for thought and discussion.  I think you make a valid point - diameter growth is directly linked to available nutrients and sunlight.  However, your comparative example is on the extreme.  Comparing White Oak to Loblolly Pine isn't apples to apples.  I would propose that if each tree had ideal growing conditions, the pine would still "outgrow" the White Oak due to species genetics (up to a certain point).  White Oak is a slow growing species even when compared to species within it's own genus.  I think a better example would be to compare two White Oak within two different growing conditions to really see what effect site has.  Or compare two Loblolly Pines.  Either way you are eliminating a variable and solidifying your position.  But I suppose your illustration would serve general public very well as most people don't know the difference between tree species so educating them that diameter size doesn't necessarily correlate to tree age would be well received.

Here is a close up of a cross section of an old growth bald cypress that came from the swamps outside of Conway, SC.



 

88 growth rings per inch and the log was almost 37" in diameter!

Here is the entire log cross section:

Had some 20" dbh Alaska Yellow cedar that had over 900 rings when counted.

Have a disk from a redwood about 35" diam with 784 growth rings.

Trees are amazing.

Have heard tell of Black spruce in central WI swamps that are around 2"-3" diam with well over 300 growth rings counted.

I always like to tell the story of the 3 foot pine that I cut with my Father. There was a smaller,about 18 inch tree that grew close to it.The plan was to leave the small one. The limbs from the big tree got the small one anyways. As I was cutting up the small one,I noticed the close growth ring.I think that 18 inch tree was as old as the 3 foot one. Suppress growth

I've heard of stunted cedar that grow on cliff faces in southern ontario that can be 500 years old and barely 2" in diameter. I think the oldest ever found was 1100 years old.

We have balsam fir up here that will live for 50 years in the shade of the overstory and never get taller than chest height.

The cookie in my picture above came from an ERC tree that was growing from one of the columns of the Windsor Ruins in Port Gibson, Ms.


 
A company was hired to remove the trees whose roots were damaging the column tops.  I was able to get one of the larger trees seen growing from the columns.   ;D

I cut this Balsam Fir a couple of weeks ago. The last ten years of growth, it added nearly 6". The first 60 years of life only gave it 5" Nice example of why active management works. 
Trees are good.

I cut a Gum Tree (MM's favorite! ;)) today that was between 50 and 60 years old. The trunk was 38" in diameter at 8" above ground level.
From this same general area, I cut a cherry tree that had 45 rings, yet was only 7" in diameter nearly level with the ground.

Like Mark and KBforester both said about balsam fir. That tree is a real trickster, for lack of a better word. It can be 50 years old and barely 2" and 4 feet tall or 20" at breast height and 68 feet tall. Last winter the neighbors cut 20" dbh fir (chalk white) that was 45-50 years old on the stump on any I had seen laid out in their yard. I've thinned 50 year old fir that was 4" on the stump, and rotten in the centre with lichens all over the branches. Old rotten junk.  It most often regenerates while the old growth fir was beginning to fall down in a red spruce dominant stand. The red spruce can live centuries, the fir dead before the first C. But of course fir grows up here in most landscapes and stand types. Bogs, hardwood ridges, cedar swamps, red maple-aspen stands...etc. Good fir needs good growing ground to start with and needs space. ;D

A Sweetgum that size can make some really pretty lumber.  I have seen it used as wall paneling as well as board and batten siding.  It saws about like Poplar.

"Comparing white oak to loblolly pine isn't comparing apples to apples".

Correct, Buckeye. But I'm not comparing oak to pine, I'm comparing age to size. I use these two "beaver biscuits" in talks to illustrate that tree size is not very well related to age. I do point out that they are different species, and that the white oak as a species grows slower than loblolly pine, but point out that this is not the reason for the vast difference in sizes at the same age.  I chose these two biscuits because they are the exact same age, and can illustrate that point without bringing in "but they are different ages so that's why they're different sizes" into the discussion. 

I first cut the loblolly pine biscuit off a stump in a pulpwood thinning operation to show how to count growth rings to determine tree age and to show how trees slow in growth and need to be thinned. The thick dark rings show up really well in front of groups.  A few years later, I was resting against a tree eating lunch while mopping up on a forest fire, looked down at the little oak stump, casually counted the rings and was surprised that it was the exact age as my pine biscuit.  Hmmmmmmmmm, says I.........I think I can use a biscuit from this.....   ;D.  And a visual aid was born.........

I could use 2 biscuits from the same species close in age, if I could find them. But these being the exact same age, I thought they would better bring home the point I was trying to make.  I haven't been able to find two trees of the same species that are the exact same age but vastly different diameters that I could cut biscuits from. The "extreme" of these two help make my point.

That looks like it was a grand old place at one time Magicman.

I often wonder what became of Lord Strathcona's mansion in Montreal, it was on two lots. Anyone I know who lives in Montreal never heard tell of the place.  Makes me some mad. ::)

There is quite a story behind those Windsor Ruins.  That was the location when part of the movie "Raintree County" was filmed staring Elizabeth Taylor and Montgomery Cliff.  I watched the filming and believe me when I tell you that a 25 year old Elizabeth Taylor was a beautiful woman, at least to a 16 year old boy.


 
Here is a marble top table that I have that was made from three of the "leaves" from atop of one of the columns.  No they were not stolen.  At the time the ruins were owned by a private landowner who gave the wrought iron pieces to us.

Great topic I like learning about the growth of trees the last track of timber I cut was old growth hard wood very tight growth rings 30 to 40 per inch up until about 80 to 100 years ago than the growth picked up I seen this in a lot of the trees I researched this and found out that the pick in growth was due to the American chestnut die off it was the dominant species here at the time when they died it gave the other trees there sun light

 :-X :-X Doesn't really surprise me as here in NB they (whom ever they are) wiped out anything to do with Alexander "Boss" Gibson. ::)

I do know Strathcona had an estate in Scotland and it recently was sold by heirs. At least his cousin's place 'Mount Stephen' still stands and the fishing lodge as well at the Reford Gardens on the Gaspe.
