Oldest trees
The oldest trees are determined by growth rings, which can be seen if the tree is cut down or in cores taken from the edge to the centre of the tree. Accurate determination is only possible for trees which produce growth rings, generally those which occur in seasonal climates; trees in uniform non-seasonal tropical climates grow continuously and do not have distinct growth rings. It is also only possible for trees which are solid to the centre of the tree; many very old trees become hollow as the dead heartwood decays away. For some of these species, age estimates have been made on the basis of extrapolating current growth rates, but the results are usually little better than guesswork or wild speculation.
The verified oldest measured ages are (Gymnosperm Database):
Great Basin Bristlecone Pine Pinus longaeva: 4844 years
Alerce Fitzroya cupressoides: 3622 years
Giant Sequoia Sequoiadendron giganteum: 3266 years
Huon-pine Lagarostrobos franklinii: 2500 years
Rocky Mountains Bristlecone Pine Pinus aristata: 2435 years
Other species suspected of reaching exceptional age include European Yew Taxus baccata (probably over 3000 years) and Western Redcedar Thuja plicata.
The oldest verified age for an angiosperm tree is 2293 years for the Sri Maha Bodhi Sacred Fig (Ficus religiosa) planted in 288 BC at Anuradhapura, Sri Lanka; this is also the oldest human-planted tree with a known planting date.

No but they can live a mighty long time recently in my home town they had to cut down a tree in the park, it was a tree that Abraham Lincoln had stood under to give a speech.

There has not been a persn around forever to verify it so no one is sure. We do know that they can last for thousands of years (based on counting annual rings on them) but most are not left alone to just age.
