The Oldest Trees on Earth
The Bristlecone Pines
They are in California, USA. They are the oldest trees alive in the world today. Some are more than 4,000 years old. The rings in their wood show how much they’ve grown. Scientists use these rings to see how the world’s climate has changed. They grow very slowly: about fourteen metres in 3,000 years!
The Wollemi Pines
They are the oldest species of tree in the world. Fossilised remains show they existed 110 million years ago. They grew in the rainforest before Australia became a continent. They grew when there were dinosaurs on Earth. The climate was different then. They still grew when plants and animals died and the climate changed. Some trees of this type still exist in Australia. Nobody knows how old these trees are. Scientists want to save them; they still didn’t reveal their precise location. They grow very fast; some are forty metres high!
