资源简介：
In 2002 the Second Atlas of Dutch Breeding birds was published. Fieldwork for the new atlas was carried out during the breeding seasons of 1998, 1999 and 2000, with some additional fieldwork in 2001 to tackle remaining gaps in coverage. A quantitative survey was added in order to allow a more detail-ed analysis of regional differences in abundance.
