The teddy bears were enjoying a walk through their local woodland. Although the trees didn't yet have many leaves, the bears still liked to walk amongst the huge tree trunks and look up to see just how tall some trees could grow - much, much taller than any of the bears!
"Oh, look!" shouted Henry. "That tree has been chopped down! That's very sad. Why would anyone do that?" he asked.
"Actually, it was probably the forest ranger," replied Bubbles. "Remember last time we were here after that awful storm and the tree looked like it had been struck by lightning? It seemed a little unsafe - some of the branches seemed ready to fall off and hit someone on the head."
"Yes, I remember now - it had looked a bit dangerous," said Henry. "I wonder how long it had been here?"
"Well, we can try and work that out," replied Charlie. "Let's look at the stump that's left. Look at the rings showing. Each of those rings is one year's growth for the tree, so if we count the number of rings, that will be how many years old the tree was."
