Based on information from breeding bird atlases, the number of red-listed species occurring per mapped grid square was determined and presented. Classes 1 (threatened by extinction), 2 (highly endangered), 3 (endangered) and P (potentially endangered) of the Red List of Breeding Birds in Berlin (Witt 1991) were applied to categorise the species encountered.
