| Abstract | The number of bird species and individuals were determined in 2 study plots (total 6,8 km2 and 105 counts) in cultivated lowlands (grassland) of Schleswig-Holstein during 1976–1984. In order to estimate the total population of selected species additional comparison sites were surveyed. In total up to 219 km2 (up to 1993) were surveyed. The average number of species observed each year was 37,4. On average 28% of the birds recorded each year were breeding species and 72% were non-breeders (of these 36% were breeding birds of the surrounding villages and woods and 36% were migrants and visitors). The average abundance was 48,1 individuals/10 ha. An almost complete exchange of non-breeders and local breeding birds occurs once a year. Estimated population sizes of dominant and characteristic species in Schleswig-Holstein are presented. Some lowland sites are very attractive habitats of international importance especially during the winter.Die Arbeit behandelt Vogelbestände im Niederungen-Grünland Schleswig-Holsteins. Die Jahresvogel-Bestände wurden auf 2 Untersuchungsflächen mit insgesamt 6,8 km2 ermittelt (1976–1984). Zur Hochrechnung ausgewählter Gesamtbestände sind weitere Gebiete (Vergleichsflächen) einbezogen, summarisch bis zu 219 km2 (bis 1993). Die Gesamtartenzahl beträgt 92 (Jahresmittel 37,4). Das jährliche Artenspektrum besteht zu 28% aus Brutvögeln und 72% aus Nicht-Brutvögeln (je 36% Brutvögel der Umgebung und Durchzügler/Gäste). Die mittlere Individuendichte beträgt 48,1/10 ha. Einmal im Jahr findet ein nahezu vollständiger Austausch von Nicht-Brutvögeln und (heimischen) Brutvögeln statt. Für dominierende und charakteristische Arten werden landesweit Bestände geschätzt. Im Winter bildet Grünland gegenüber anderen Agrarflächen ein sehr attraktives Habitat. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
