What is the oldest tree in the world?

The oldest tree in the world is a bristlecone pine (Pinus longaeva) named “Methuselah,” located in California’s White Mountains. This tree is estimated to be over 4,800 years old. Bristlecone pines are known for their ability to survive harsh climates, poor soils, and high altitudes. Methuselah’s exact location is kept secret to protect it from damage. These ancient trees provide valuable insights into past climates and ecological changes, as their growth rings serve as natural records of environmental conditions.
