How do they tell its age? By cutting it down and counting the rings?

Sorry, I couldn't help it...

According to the article, the tree's true age was revealed by carbon-14 dating its root system.

Modern thinking.

Interesting either way they take a piece out, it seemed to me disturbing the root system would be more invasive than the plug but then again WTHDIK.

A very small amount of material is needed for carbon-14 dating and the oldest dates that can be reliably measured by this process date to around 50,000 years.

One of my favorite poets is Gary Snyder. His c.1960 book of collected poems, "Earth House Hold" (the literal translation of the word "ecology") is rooted in Buddhism and nature and has been often cited as awakening the popular Environment movement. While I very much enjoy his works I dont post about that here because it seems irrelevant to our Silverwing forum. My 2¢

You not so far off. In the 1960 our Forestry Service allowed research on the oldest living tree in the USA (4600 years). In doing so the researcher cut it down to study it.

This tree was believed to be the oldest living thing in the world.
