And if you don't know when the tree was planted, just ask the tree it's birthday, duh.

Just be sure to avoid the ents, they are quite defensive about their age and may raise their voice by a decibel

If you don't know when it was planted, then just cut the tree down and count the rings. Easy!

[–] BuboScandiacus@mander.xyz 8 points 1 month ago (2 children)

And how much time is equal to a ring ? Four seasons ?

[–] jol@discuss.tchncs.de 19 points 1 month ago (2 children)

I think one human year equals 7 tree years, or something. So if you know when the tree was planted, just multiply by 7!

[–] milicent_bystandr@lemm.ee 5 points 4 weeks ago

That's the wrong sort of bark!

Assuming you live in a region with 4 seasons per year, then yeah.

From what I understand (and according to this), the lighter parts of the rings get created when the tree grows rapidly, which typically happens in spring. And the darker parts get created during slower growth, which typically happens in summer. In autumn and winter, trees tend to not grow.

You can tell because of the way it is.

Here's the rest:

Current year - year tree was planted = age of tree

Unless it's excel and the tree was planted before 01-01-1900

[–] gedhrel@lemmy.world 6 points 4 weeks ago (1 children)

Excel famously misidentifies all trees as dates.

[–] Akasazh@feddit.nl 3 points 4 weeks ago

Except for the date palm, it just gets confused and begets an interest in marijuana

[–] niktemadur@lemmy.world 1 points 4 weeks ago

???
Profit!

[–] psud@aussie.zone 1 points 3 weeks ago

I think you're looking for the one referring to lack of pixels

[–] underwire212@lemm.ee 16 points 1 month ago

If X, then X

[–] anarchist@lemmy.ml 14 points 4 weeks ago

At least it's not wrong

[–] Kolanaki@yiffit.net 13 points 4 weeks ago (2 children)

You could just ask. 🤷🏻‍♂️

[–] WhiskyTangoFoxtrot@lemmy.world 4 points 4 weeks ago

Never ask a tree their age.

[–] niktemadur@lemmy.world 3 points 4 weeks ago

Or maybe you could just Google it.

[–] Hazmatastic@lemm.ee 11 points 1 month ago

This does have real implications in dendrochronology. If you were to take a beam from a structure built hundreds or even thousands of years ago, you can use ring spacing along with climate records of the area it was cut down in to determine when it was cut down, which will tell you the approximate age of the structure (and as a result, the tree). The rings can reflect events such as floods, fires, droughts, and periods of rapid growth, so if you can match those up with climate records and known samples, it works out the way the graphic describes.

When did someone train a Flat Earth AI to answer Google questions

[–] Whelks_chance@lemmy.world 8 points 1 month ago

Also a good way to make sure it doesn't have any more birthdays

[–] Sam_Bass@lemmy.world 8 points 4 weeks ago* (last edited 4 weeks ago)

Oh i dunno, basic math seems to elude so many i wouldnt count on them knowing how old a tree is by having the date it was planted

[–] expatriado@lemmy.world 7 points 1 month ago

if you planted from seed, some trees from the nursery may be 8 years old or older, specially those that come rooted in 45 gallon containers

[–] veganpizza69@lemmy.world 5 points 4 weeks ago* (last edited 4 weeks ago)

The great thing about this test is that this age value will remain constant after taking the measurements.
