The nature reserve Calauer Schweiz has a wide variety of plants. A blaze of colour is revealed to the observer, which is hard to find anywhere else in Germany. Even endangered plant species like the royal fern are here at home.

The forests of the Calauer Schweiz distinguish itself especially through its fungi riches. Common and forest pines, which are partly up to 150 years old, red oaks, English pines and white pines grow in the little valleys and on the heights. Blueberries, bilberries and lingonberries are growing on the slopes. High above in the pines one can see green bushes.

It is the evergreen mistletoe, a half parasite, which lives with its sinker roots anchored at the branches. The whitish berries, poisonous for humans, are loved by birds. The mistletoe is a forest pest that might bring the tree to die off.  

At the valley one will meet some marshy areas. Growing there among others are round-leaved sundew, common erica, the marsh violet and the narrow-leaved cotton grass as well as ripped fern and royal fern.
