Bristlecone Pine Tree


Bristlecone Pine Tree

DID YOU KNOW THAT . . . Trees live much longer than any other type of plant or animal? In fact, it is possible to know the age of a tree by counting the rings in its trunk (one ring generally equates to one year). The oldest living tree and hence one of the oldest known living things on Earth is a bristlecone pine tree in California, North America. It is over 4,600 years old.
