How wonderful it is to have a forester as an uncle! This way, Leo and Carolina can stay in the forest house in the middle of the woods when they visit their cousin Timm. Timm has a friend there who is already three hundred years old: a majestic oak tree! This allows the city children to observe all the native animals, from woodcock and cuckoos to deer and badgers, and even a sounder of wild boars. They also learn about evergreen plants and primroses, as well as mushrooms and insects, which are detailed in an appendix. This is the new edition of the children's non-fiction classic by Gerda Muller from 1991.
