• My nomination for the pi fight:(8+ / 0-)

The standards for the American Forests tree champion specify that you measure circumference in inches. Then they go on to say:

1. Measure the distance around the trunk of the tree, in inches, at 4 ½ feet above ground level. This point is called the diameter breast height (dbh).
Oh noes, the pi fight is on! No wonder the public gets confused about diameter and circumference.

By the way, their champion spruce pine is about 3.7 feet in diameter. And 156 feet tall, which is very impressive.

• but when comparing they do give the measure(7+ / 0-)

as a diameter right?

As a by the way I've seen tropical hardwoods that have a very wide flare towards the bottom that begins at least ten feet up. notice my purple day pack bottom L

How big is your personal carbon footprint?

• Most foresters use diameter,(6+ / 0-)

generally measured 4.5 feet above the ground. Sometimes this must be adjusted to account for abnormal form. When estimating the volume of a log, the better programs also require diameter estimates higher up the tree, since trees come in so many different shapes.

The American Forests group uses circumference in its measurement of champion trees, which confuses everyone, including their own people, as evidenced by my comments above.

• And I should add(6+ / 0-)

that one method to directly measure diameter is to wrap a steel tape around the circumference of the tree. The increments on that tape are inches times pi, thereby allowing you to read the true diameter.

• I called my forester and asked a few questions...(6+ / 0-)

He said, 'Damn, fb's a really good cruiser. But, will he work in Wisconsin in winter?'

I like pi. Apple's my favorite, with vanilla ice cream.

I'm waiting on your next story.

I love nature, science and my dogs.

• With a bit more global warming,(6+ / 0-)

perhaps I would work there in the winter. Until that happens, the warmer months are more to my liking.

I'm sure your forester knows the difference between circumference and diameter!
