How old is the oldest living tree?

The question

How old is the oldest living tree?

Efficient

The oldest known living tree is a Great Basin bristlecone pine (Pinus longaeva) located in the White Mountains of California. It is estimated to be approximately 4,855 years old.

While there are other clonal colonies—where a root system produces genetically identical trunks over thousands of years, such as Pando in Utah or Old Tjikko in Sweden—this bristlecone pine holds the record for the oldest non-clonal, single-stem tree.
