Mammals (Mammalia) are a class of vertebrates. There are about 5,000 to 6,000 mammal species worldwide, of which only about 1% live in water. Typical characteristics of mammals are nursing the offspring with mother's milk, body hair and that - with a few exceptions (cloacal animals) - the offspring are born alive.

Some time ago, the beaver (Castor fiber) migrated into the area via the Schaale.

The Biosphere Reserve with its richly structured landscape is a high-quality habitat for bats in many areas. Nine species have been identified so far. Two species can be presumed to occur, as they have been found in the surrounding area:
