 A colony of 47,000 quaking aspen trees (nicknamed Pando), covering in the Fishlake National Forest of Utah, is considered one of the oldest and largest organisms in the world.The colony has been estimated to be 80,000 years old, although tree ring samples date individual, above-ground, trees at only an average of about 130 years.A colony of Huon pine trees covering on Mount Read (Tasmania) is estimated to be around 10,000 years old, as determined by DNA samples taken from pollen collected from the sediment of a nearby lake.
