Dutch Centre For Field Ornithology (SOVON) - Breeding Bird Atlas 1973-1977 - metadata

Latest version published by Dutch Centre for Field Ornithology (Sovon) on Jan 25, 2017 Dutch Centre for Field Ornithology (Sovon)

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.

Sampling Methods

The following general information was gathered for each square. The year from which the data originate, the survey completeness and some other relevant factors such as soils, lack of standing fresh water, heath, coniferous woods, broad-leaved woods and moorland. For all observed species the breeding evidence was note using one of 16 codes subdivided into three categories: Confirmed breeding, probable breeding, possible breeding or present. For the first two categories an estimate of the number of breeding pairs was made.

Study Extent The Netherlands, 1974-1977. Fieldwork was carried in squares based on a 5 km grid. All 1971 squares except one very small one were surveyed.
Quality Control The data was validated by district coordinates

Method step description:
