There is a such a lack of respect in the world these days. Does that statement make me sound old? Oh well (:

I love the way the bark spirals its way to the top. If you look at the limbs, they mimic this swirling.

It is very sad that some people would want to vandalize anything natural let alone one of the world’s oldest trees.
But vandalism in the form of street art and graffiti is an adaption to ones environment; it is a product of this modern society we live in. It is used to express emotion and to break free from the chains society puts people in. When it comes to vandalizing trees like this tho, respect is definitely needed.
I don’t think it makes you sound old, respecting the environment is an all ages thing but you shouldn’t be critical of all vandalism.

That is the Fibonacci sequence for you, the spiral is everywhere in the universe!

I can and will be critical of all "vandalism" Why should one person be allowed to vandalize another's work...ever? vandalism is the refusal to accept the work of those who have came before. Let me guess you are the type that tore the arms from David...for the sake of your art? Absolutely unacceptable reasoning for the destruction of a persons art.

how do they know that first tree is 9550? carbon dating? im just curious, i know a lot of tree's to the counting rings thing which is why i ask. (that one would have to have microscopic rings)
Longevity of clonal plants: why it matters and how to measure it
Scope Here, we critically review the present knowledge on the longevity of clonal plants and discuss its importance for population persistence. Direct life-span measurements such as growth-ring analysis in woody plants are relatively easy to take, although, for many clonal plants, these methods are not adequate due to the variable growth pattern of ramets and difficult genet identification. Recently, indirect methods have been introduced in which genet size and annual shoot increments are used to estimate genet age. These methods, often based on molecular techniques, allow the investigation of genet size and age structure of whole populations, a crucial issue for understanding their viability and persistence. However, indirect estimates of clonal longevity are impeded because the process of ageing in clonal plants is still poorly understood and because their size and age are not always well correlated. Alternative estimators for genet life span such as somatic mutations have recently been suggested.
How to Tell the Age of a Tree Without Cutting it Down
The easiest way to tell the age of a tree is to cut it down and count the interior rings. But what do you do when you don't want to cut down the tree but want to obtain a general estimate of its age? One way is to have a professional obtain a core boring of the tree and count the annual rings. This method, however, is invasive and may damage the tree. Another method, developed by the International Society of Arboriculture, requires only some simple measurements and calculations to obtain a good estimate of a tree's age.
Estimate a Tree's Age
1
Wrap the tape measure around the tree at about four and a half feet above the ground. This measurement is the tree's circumference. Write down this measurement.
2
Use the circumference to find the diameter of the tree. The formula for finding diameter is: Diameter = circumference divided by 3.14 (pi).
3
Determine the age of the tree by multiplying the diameter by the growth factor.
A new device allows the non - destructive inspection of standing trees for cracks, cavities, and rot. It is based on the simultaneous measurement of the time of transmission of stress waves by several sensors arranged around the stem. The system was extensively tested by comparison of the tomogram with either the cross - section of the tree cut after the measurement, or with data from penetrometers or increment cores obtained in the same plane. The border of cavities is identified to the nearest cm, whereas the with of cracks in the tomogram depends on the position of the sensors around the stem. Rots are identified as soon as the wood is sufficiently deteriorated to reduce the velocity of sound. This system may become a valuable tool for hazard tree inspection, evaluation, and management.
