How to determine the age of a tree WITHOUT cutting it down

[@edwardj.persleyiii3903]

To anyone that needs help with the calculations I have done this many times myself the they way you do it is you take a measuring tape and measure the circumference of the tree trunk about chest hight then you take the circumference and divide it by 3.141592 (pi) this gives you the diameter. Then you’ll have to find out what species it is when you do, then you’ll have to look up the growth factor for that species then your going to multiply the growth factor times the diameter to get an estimated age . The real age could be plus or minus 10 years but this is the most accurate way without harming the tree hopes this helps someone.

[@snail9552]

My results are inaccurate because I’m dumb at math or the tree branches out after 17.12 inches or something like that

​@snail9552 I think it would be okay if you just do the measuring at the closest spot around chest height where there are no branches. Don't want to do matg with screwed up numbers. Your final answer will be even more screwed up.

[@arturovaldes546]

Thank you ❤

[@cincofive2027]

I measure a tree today at 180 inches so according to your method is 286 years thats awesome the tree seems very happy 👍

[@edwardj.persleyiii3903]

What is the species?

I live in Oregon and I'm very impressed by that tree. Hardwood does not grow tall and straight like that here in the northwest.

[@falllineridge]

Darrel Carson Interesting! Thanks for sharing!

[@Debtfreehomesteaders]

New Sub! I think it's kind of neat that you can get a rough estimate on a tree like that. 150 year old tree really makes you think of what it's been through. Thanks for sharing! -Will

Thank you ! Unfortunately this Oak Tree that I love has been struck by a lightning , ripping out all of its insides . Its hollow and burned from the ground to the middle..

[@micah_lee]

Because this isn’t very accurate

[@justiceprevail1552]

When the system shown above was used to find the age of a tree in Virginia, (they actually knew the age), it ended up being more than twice the actual age of 85. So what is a more accurate way of finding out the age without cutting it down or taking a bore sample. Well Dr. Charles Byvik of Virginia stated that a more accurate formula is to use the Radius of the tree: (Circumference/(2 x 3.14) x growth factor. The tree used in Dr. Byvik demonstration was an Willow Oak which has a growth factor of 3, with an 180" in circumference. Using his formula shown above, the circumference is divided by 2 times PI which equals 6,28, so 180" divided by 6.28 x the growth factor of 3 equals an age of 85 years, which was the actual age of the tree. If the formula shown in the above video using the diameter instead of the radius, Dr. Byvik's tree would have been 172 yrs old. If Dr. Byvik formula is accurate then the tree measured in the above video is actually 76 years old.

[@micah_lee]

It all just depends on the growth conditions. Can’t be totally accurate without counting growth rings or knowing when it was germinated

[@muaadhbawa5963]

what would be a good source to find growth factors?

[@akshayasadventures]

Something about this southern accent makes them feel more trustworthy and honest. Or maybe its just this guy's way of explaining everything without being full of himself. Great video,, Thanks.

[@FiloBetto74]

About 10ft from the front door of my cabin stands a perfect post oak estimated to be 250 years old. If we both hugged it we could almost touch fingertips (bout 3-4 inch gap). The county sends an arborist out once a year to check on it. That guy says it's one of his favorite oaks. I said "me too". Lots of shade!

[@somalena8835]

Wow this is awesome. Thankyou. I live in oregon and there are so many trees that are huge here.....assuming they are even older than the tree you just determined there.

[@micah_lee]

Every tree individual and species is different. I have a tree just a bit smaller than this in my backyard. I found pictures of it from back in the year 2002 ish. It was literall a baby little tree. (For clarity it is a pecan tree, which is related to hickory trees and is native to north america.) It looked like 4 inches in diameter. Now it is past two feet and seems like a massive tree. But it just must have had exceptional growth conditions. You have to take it case by case. Some of the oldest trees are not very big compared to others.

[@rosettevillamor9052]

Can you help me please. This is the information I searched for from Google. Is says the following: How quickly do coconut palm trees grow? Coconut palms grow at a moderate rate, putting on 1-2 ft. per year, provided that the needs of the plant are met. Given this information, what is the growth rate of Coconut Tree? Thank you 4:31

[@basit4135]

Thank you for such a simple and great information

[@paulfalzarano5930]

Excellent video, great information, thank You!

[@mro5858]

Very interesting. Thank you. I am a Physics graduate student and was wondering how scientist measure the age of trees. Can we do the same calculation using branches?!!

[@micah_lee]

Unfortunately this method isn’t as accurate as using growth rings. If you don’t want to cut down a tree, you can use an increment borer to get the age

[@youknoweverything7643]

Thank you for this information we have a giant oak tree in our backyard massive it's right next to the house and it's about 130 ft tall it is very beautiful oak tree and mine is literally 150 inches round so now I'm gonna measure it my guess is 250 years ago and I'm going to use my tire stagger tape for racing for the measure it because it's meant to flex around round surfaces to measure the outside diameters of race car tires so it'll be more accurate than a regular tape measure

[@vincent-ataramaniko]

Hi thanks for the vid! However, the tree I'm measuring is a chestnut and I couldn't find its growth factor. Does anyone have a link of a more complete list of growth factors? Thanks!

[@FacesintheStone]

Super cool, I’m trying to find the age of some dead trees in a Native American site. They’re all painted and everything it is pretty neat.

[@dogsareawesome9197]

Question, if a tree splits below chest height into multiple trunks, do i measure the tree below it splits? Or one of the trunks?

[@heatnicoleher]

What is the growth rate of a weeping willow?

[@truesouthsawmill4151]

I think you need to divide the diameter by 2, or half it, then multiply by your growth factor. When you count rings on a felled tree, you start at the pith and count out to the bark. So your only counting rings of half the diameter....I think, lol!

[@peheather]

Perhaps that has already been taken into account in the calculation of the growth factor - the reference provided clearly instructs one to use the diameter of the tree rather than the radius

[@GawoniiAustenaco]

Does it matter if the tree forked at beast height, how would you measure it if at breast height, the tree branched off in three directions?

[@JM-hl2gy]

thanks for posting, my oak is slightly older, during the winter a branch fell off and two of it's lowest branches lost bark, Is it dying? it's so huge and tall I may have it cut down than fall on my house. I live in the mid- Atlantic region.

[@micah_lee]

I hope your tree has not fallen yet. I would suggest getting an aborist out to check it out

[@rebeccasuerdieck5083]

[@jrnumex9286]

if it's a rough estimate to begin with then a diameter line up with tape then pi faster .

Why do you measure the circumference of the tree at the 60 inch height?

[@mosana19]

But how could I make this calculation if I use centimeter instead of Inch?

What is the growth factor of a sycamore tree?

[@blakespower]

I tried this with an american beech on my property and it says its 200 years old and several yellow poplars were over 100 years old, then I tried this on a bald cypress I planted in 2004 and it said it was old as the year 1989, so I guess it is give or take 15 years, and I suppose forest trees may be older since they dont get full sunshine

I saw a tree around that big sawed down. Counted the rings and got 90 years old.

I believe my oak is slowly dying. But it still grows leaves. But has many signs of it being sick.

[@alexthai2456]

could you tell me how to know the weight of a tree without cutting it down??? thank you

[@luc7478]

i think it's a physics problem : Calculate the volume of the tree suppose it has cylindrical shape . Multiply the volume by the density of the wood , and you'll find the mass.

[@luc7478]

Masse = volume x density

[@gls9902]

The simplest, easiest and most accurate method to determine the age of any tree? These books can give you a lifetime of information about trees and the essential role they play in the very existence of homo sapiens on this planet. Without trees we would not exist, it's that simple. “Trees of Power” By Akiva Siver “The Hidden Life of Trees, What They Feel, How They Communicate” By Peter Wohlleben ~ Peter has written 18 books about trees “Finding the Mother Tree, Discovering the Wisdom of the Forest” by Suzanne Simard “Tree Talk” by Dianne Robbins The seed of this magnificent ancient tree was lofted to this location on the winds of God. Landing in this location, successfully germinated and took root in the spring of 1635. All I did to find out how old the London Plane (Platanus X acerifolia), is in my yard that is nearly 12 feet in circumference ABH, I just asked her.

[@ikibucukmil]

just measure one side and multiple it with pi number, it gives you total measurement😅

[@ralocunninghamthe3626]

I hope you make some friends..So you can measure the trees age togethr...

[@Usernamenotabailable]

This is the funniest shit I've ever seen. Why wouldn't you use a loggers tape? DBH is measured strictly at 4.5 ft. so that the same measurement can be achieved by multiple people.NOT between 4.5/5ft. Obviously you've never done any real tree measurements and are assuredly NOT a certified timber cruiser. Just bore the tree and count the rings.
