Here's a gadget that I don't need but sorely want!  It's for measuring the diameter of trees, useful for determining whether a tree can be rightfully called a champion or heritage tree.  How often would I use it?  At least once, I suppose.

down in the south Pi is "3" ;) j/k

looks like it would easy enough to take a regular tape measure, and write on the back of it, various sizes, and divide by Pi; or just even a cloth style measure, which weighs nothing, and approximate in your head, or use calculator/phone or even a little wallet chart.

i suppose for a plumber, who is doing this day in and day out it might be useful.

actually, if the size is the pure limiting factor, you could make a string the right length, and trees that are bigger won't fit, and would be heritage, and lesser trees would meet or overlap and wouldn't be (and thus are edible?)

The limiting factor is my utter lack of confidence in my math abilities. ;)

insert joke here about doing an integral (tree) with limits :)

I want one, too. I've been obsessing on the trees that I know, lately. I would like to document them.
There's a ponderosa that I really want to measure. Long ago my grandpa, a forest ranger, said it was the most beautiful specimen he had ever seen. And it really is a grand.

But think of all the other things you could find the diameters of too!

Dogs!
People's heads!
Coffee cups!
Lamp posts!
Cigars!
Soup cans!
Flower pots!

The possibilities are endless!

what is a heritage tree? the link doesn't go to heritage trees....

You have to scroll down a bit to the heritage tree part. It's a legal definition that protects a tree from being cut or molested. It varies from place to place, and not everywhere has that designation. It seems to be a popular route of protection for Canada and the PNW.

A tailor's tape measure or anything like that works perfectly well! I was part of the city street tree census years back, and they just gave us one of those to measure circumferences. Plug that number into a cell phone calculator and divide by 3.14, and you're golden!

That's exactly what I was going to say. A tailor's tape is like 99 cents and if you're trying to impress people on nature walks, they'll be more impressed with quick math than a twenty buck gadget.

Do they make 20 foot tailor's tape?

Generally they're about ten feet. If you really need twenty feet then you can buy a second ten feet bringing it to a wopping $1.98. On the other hand, if you find a tree in New England that's more than three feet in diameter, I want to see it.

The tree I want to measure is the last one on this post. I'll see where I can get a tailor's tape.

Cool. You can get them anywhere you can by cloth. I'll gewt you the fancy one when you get to oregon where the tree just aren't messing around.

Haven't found anyone selling them over 5 ft (150 cm). Doesn't mean they don't exist, but it seems to be a specialty item.

Joann Fabrics has a 120" tape for $1.

Would work for little trees (the majority of urban trees, which have an average life span of 5-10 years, as I understand it) but I'm curious about some of the big red oaks and european beeches in the parks near my house. Those tailor tapes seem to come in a standart 60 inch/150 cm length.

Plus you're expecting me to figure out how to use an app on my phone, which is worse than expecting me to do math! :P

THANK YOU. Can no one understand when a guy just needs validation to buy a gadget?
