Spiertin 05: Knorrige Greise

Auf dem Bild siehst du die 3 Baumarten Lärche, Arve und Fichte.


Where the ice of the glacier retreats, life must start from scratch. First, a desert of stone and scree emerges from under the ice. It takes hundreds of years for a forest to grow like the one you just walked through.

Now listen to what Spiertin has to tell you in the audio. The audio file can be found at the back of the pictures. 

How to recognize the age of trees?

To find out the exact age of a tree, the tree rings inside the trunk must be counted. For this purpose, either a tree can be felled, or you take a special small drill. The experts - they call themselves dendrologists - can use it to pull a small drill core from the trunk and count the tree rings.
