In 1979 the Atlas of Dutch Breeding birds was published. Fieldwork for the Dutch Atlas was carried out in the years 1973-1977 according to the rules of the European Ornithological Atlas Committee. To aid interpretation of the breeding bird distribution some relevant factors were mapped such as soils, lack of standing fresh water, heath, coniferous woods, broad-leaved woods and moorland.
