what is the oldest tree in the world?
The oldest tree in the world is the Great Basin Bristlecone Pine, which has reached an age of over 5,000 years. The extremely cold temperatures and high winds, coupled with a slow growth rate, contribute to the development of dense wood. This density provides the tree with immunity against insects, fungi, rot, and erosion. Additionally, the needles on the tree can live up to 30 years, enabling the tree to conserve energy by not requiring the production of new ones.
