Target
The Dachverband Deutscher Avifaunisten (DDA, Federation of German Avifaunists) co-ordinates
national-wide bird survey programmes, such as monitoring of breeding and resting birds. As well
as supporting reseach on applied bird conservation, the DDA represents German nature conser-
vation organisations on Wetlands International and the European Bird Census Council.
Since more than 100 years the Naturschutzbund Deutschland (NABU, Nature and Biodiversity
Conservation Union) is involved in practical and political bird and nature conservation. The
NABU is the German partner of BirdLife International, it is member of the DNR (German League
for Nature and Environment), and since 1971 the NABU chooses the Bird of the Year in Germany
(2008: common cuckoo).
The Deutsche Rat für Vogelschutz (DRV, German Council for Bird Protection) is a forum, which
enables the co-operation and an intensive exchange of experiences between representatives of
governmental bird conservation agencies, scientific institutions and NGOs. The aim is to give
scientifically well-founded advice to decision takers and to promote scientific knowledge and
conservation strategies.
The Bundesamt für Naturschutz [Federal Nature Conservation Agency] has funded
the printing of this report with resources from the Bundesministerium für Umwelt,
Naturschutz und Reaktorsicherheit [Federal Ministry for the Environment, Nature
Conservation and Nuclear Safety].

Key points
Overall situation
Many common bird species are in decline: numbers of 23 of the 64 commonest German birds
have fallen over the last 15 years. Even species such as house sparrow, common house martin and
northern lapwing continue to deteriorate in status.
Ground-nesting birds of farmland such as Eurasian skylark and Eurasian curlew are particularly
threatened: causes are intensification of agriculture, loss of semi-natural wet grasslands and the
recent use of fallow land for the cultivation of energy crops. Favourable trends are found only where
there are high levels of organic farming and in large protected areas. If biodiversity loss is to be halted
on agricultural land, support measures must be targeted more strongly at the conservation of species
and habitats. An important current issue is the need for a fallow land programme to compensate for
the loss of EU set-aside.
Forest birds have shown a slight recovery: semi-natural forest management has led to better living
conditions for typical species such as Eurasian nuthatch and great spotted woodpecker. Nearly half
of the 52 commonest woodland species have increased since 1990, but this increase has taken place
almost exclusively outside forests, in parks, gardens and green spaces. Sharp rises in the price of tim-
ber and increased use of wood for fuel are currently causing severe intensification of forest manage-
ment. Therefore, declines in forest birds should be expected in the future.
Species breeding on the coasts are particularly seriously threatened: Kentish plover and little tern
need targeted protection measures if they are to survive in Germany. Numbers of shellfish-eating
visitors to the Wadden Sea, such as red knot and common eider, have shown alarming declines over
the last 10 years.
Long-running protection schemes have helped spectacular larger birds: continuing population
increases for black stork, white-tailed eagle, peregrine falcon and common crane show that volun-
tary- and state-sector conservation measures can enable the long-term survival of these species.
Sustainability
Birds are policy indicators of the sustainability of land-use in Germany. The Federal Government’s
sustainability strategy sets a target of stabilising the status of all species in the species diversity
indicator and those selected to represent high value habitats.
The indicator has stagnated over the last ten years and in 2005 only 74% of the target had been met.
Significant extra effort will be needed if the sustainability target is to be achieved.
Climate change
Climate change also affects bird life: numbers of ducks wintering in Germany have increased,
because the winter range of some species has moved in response to milder winter conditions in
central Europe.
Long-distance migrants such as tree pipit, wood warbler and European pied flycatcher suffer from
dramatic changes in landscape, on migration and on their African wintering grounds. Causes are
drought, overgrazing, deforestation and expansion of desert.
Long-distance migrants are particularly strongly affected by population declines, regardless of habitat
preference, ecological guild, or genetic kinship. Therefore, rapidly changing conditions on the
African continent should be brought more strongly within the focus of nature conservation.

Target
The Dachverband Deutscher Avifaunisten (DDA, Federation of German Avifaunists) co-ordinates
national-wide bird survey programmes, such as monitoring of breeding and resting birds. As well
as supporting reseach on applied bird conservation, the DDA represents German nature conser-
vation organisations on Wetlands International and the European Bird Census Council.
Since more than 100 years the Naturschutzbund Deutschland (NABU, Nature and Biodiversity
Conservation Union) is involved in practical and political bird and nature conservation. The
NABU is the German partner of BirdLife International, it is member of the DNR (German League
for Nature and Environment), and since 1971 the NABU chooses the Bird of the Year in Germany
(2008: common cuckoo).
The Deutsche Rat für Vogelschutz (DRV, German Council for Bird Protection) is a forum, which
enables the co-operation and an intensive exchange of experiences between representatives of
governmental bird conservation agencies, scientific institutions and NGOs. The aim is to give
scientifically well-founded advice to decision takers and to promote scientific knowledge and
conservation strategies.
The Bundesamt für Naturschutz [Federal Nature Conservation Agency] has funded
the printing of this report with resources from the Bundesministerium für Umwelt,
Naturschutz und Reaktorsicherheit [Federal Ministry for the Environment, Nature
Conservation and Nuclear Safety].
