Atlas of German breeding bird species

from Wikipedia, the free encyclopedia

The Atlas of German Breeding Birds (ADEBAR) is the first nationwide atlas based on uniform recording methods on the distribution, frequency and population development of all breeding bird species in Germany . ADEBAR was published in 2014 by the Vogelmonitoring Deutschland Foundation and the umbrella association of German Avifaunists (DDA) eV .

prehistory

In the FRG and the GDR there were atlases of the breeding birds, but they were based on data from the 1970s and 1980s. After reunification, Götz Rheinwald developed a semi-quantitative atlas on 25 × 25 km² grid fields in 1993 using various regional maps from the mid-1980s with widely differing recording methods. In 1998, the umbrella association of German Avifaunists , the German Council for Bird Protection and the state bird protection centers decided to create an all-German breeding bird atlas based on uniform quantitative mapping methods.

In August 2003, the Vogelmonitoring Deutschland Foundation was established in Chemnitz (renamed the Vogelwelt Deutschland Foundation, SVD in 2015). In close coordination with the DDA, she took the lead in the implementation of the ADEBAR project. In October 2003 the Federal Agency for Nature Conservation (BfN) commissioned the DDA to carry out the research and development project “Monitoring of bird species in Germany”. The methods and procedures developed as part of the project could also be used for ADEBAR. In September 2004, numerous representatives of ornithological state associations and nature conservation authorities from almost all federal states met in Dessau for the first ADEBAR specialist conference and gave the joint go-ahead for the project.

Results

In the period 2005–2009, 280 species of birds were breeding in Germany, 248 of which were regularly native species . The rest is distributed among irregularly breeding or alien bird species . A total of around 80 million pairs of birds breed in this country. This means that there is one pair of birds for every inhabitant of Germany. By far the most common species are the chaffinch and blackbird , each with over eight million pairs, followed by the great tit with more than five million pairs. Together with 19 other species, whose populations reach over a million pairs, they make up 80 percent of all breeding birds in Germany. Not only are these species very common, but they are also widespread. About a fifth of all native breeding bird species populate more than 90 percent of Germany's land area. On the other hand, with almost 100 species, there are around twice as many that breed on less than ten percent of the land area. Many of these species are endangered, such as the reed warbler , whose populations have declined sharply and can only be saved from extinction with the help of very great protective efforts. It is clear that many species that were once common in the agricultural landscape have cleared large areas of the breeding area that was still populated in the 1980s . The species with the greatest decline in the population since the mid-1980s is the partridge , the species with the greatest loss of area is the crested lark , closely followed by the 2013 bird of the year , the common snipe . But there are also positive developments: the stonechat , for example, has spread widely. The populations of some rare species such as sea ​​eagles and cranes are also developing positively. Overall, the majority of species whose breeding area is disappearing.
