What Is the Oldest Tree on a Mountain?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. What is the oldest tree on a mountain?

The Big Idea

The oldest tree on a mountain is the bristlecone pine! Bristlecone pines high in the White Mountains of California can live almost 5,000 years. That is older than any other single tree known.

Tough Home

Step one: a tough home. They grow in dry, rocky soil with strong winds and long winters. Not many things can live in such a harsh place, so the pines face little competition.

Slow Growth

Step two: slow growth. Bristlecones grow very slowly, adding only a thin ring of wood each year. Slow growth makes their wood very tight and strong, which helps it last for thousands of years.

Wood That Lasts

Step three: wood that lasts. Their wood is dense and full of sticky resin, which keeps away insects and rot. Some parts of the tree can die while the rest lives on.

A Closer Look

Let's take a closer look! Poor, rocky soil gives few rivals. Strong wind shapes the twisty, gnarly trunk. Dense wood resists rot. And sticky resin keeps insects away.

Quick Facts

Quick facts! One bristlecone pine is almost 4,900 years old. It was already growing when the pyramids of Egypt were being built. Scientists read tree rings to learn about the past, like old droughts, cold years, and wet years. Visitors keep to the trails to protect these ancient trees.

Think Like a Scientist

Now, think like a scientist! Make a timeline with the pyramids and a bristlecone pine on it. Mark about 4,500 years ago and about 4,900 years ago. Which one started growing first? Share what you discover with a grown-up.

Outro

Bristlecone pines are the elders of the mountain forest. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
