 Re: Age of a tree
Atula, what I thought, simply a mathematical calculation based on ave annual ring growth for species divided into trees radius.
Things change, often on cut trees you'll notice that the inner rings are wider than the outer, that's opposite to Mario's post (but Mario is corrrect too). The reason is if all things never change (environmentally/water/soil etc) as the tree gets older it has a larger surface area (mass) to grow another shell over. Also as the tree gets mature and consumes more of the resources around it ... it grows slower.
It's a theoretical method, an educated guess.
Recently at a job there was a HUGE FICUS tree, massive. The owner planted it and knew exactly how old it was. It was only 18 years old! I guessed 30 to 50 but what happened is he lives near the beach on sand and there's underground water only 8' down. This monster has tapped that and gone nuts. When you cut it latex runs out of it like a tap. |
