The Oldest Living Trees on Earth

There are several ways that trees can be classified as the oldest living;

  1. Continuously standing trees, those that have grown from seed, produced a trunk that is still alive.
  2. Cloning new growth ability, these trees have grown from seed, produced trunks which may have died, but produce new stems from the same root stock.

These are trees that have grown from seed, produced one, or more trunk(s) that at least one is still alive.
This is the more common perception of the oldest living tree.

These are trees that have started growing from a single seed, produced trunks, which may have died, but has continued to stay alive by growing new trunks from the same root stock.
So even though trunks may come and go over time, as long as the original rootstock remains alive, the tree is still living. These trees have proven to be the oldest living organisms on earth. See Aspen Tree Colony.

Photo of the "Pando" colony of a single male Quaking Aspen (Populus tremuloides) located in Utah, USA. All the clone trunks are determined to be part of a single living organism by identical genetic markers and are all connected by one continuous large underground root system. See Aspen Tree Colony.
