Sand areas were deposited here during the Ice Age. These were important sources of raw materials for the construction industry during the division of Germany. This created an 18-hectare pit in the Grunewald, between 15 and 25 meters deep. Where it reaches below the water table, shallow waters and wet willow breaks have developed.

The sand pit in Jagen 86 (colloquially: gravel pit) is a nature reserve with a size of about 13 hectares in Berlin's Grunewald.
It emerged from a former gravel pit that was used industrially from 1966 to 1983. Today there are over 300 fern and flowering plants, wasps and wild bees, 16 breeding bird species, seven amphibian species and 188 butterfly species.(Source: Wikipedia)
