Thus far, the indicator "biodiversity and landscape quality" has been developed as part of the National Sustainability Strategy (Federal Government 2002, new edition 2016). It is based on observing the population development of ten bird species in the entire agricultural habitat. The sampling grid used is representative for Germany. For a differentiated evaluation of individual agricultural areas it is necessary to coordinate the data and to include further important indicators. This extension is currently being worked on. Networking with other institutions and disciplines plays an important role in providing comprehensive assessments of biodiversity in the agricultural landscape. The scientific support of this focus is provided by the ThĂĽnen Institute Biodiversity in the department of the Federal Ministry of Food and Agriculture.
In addition to the indicator "Biodiversity and landscape quality", the sub-indicator "Genetic diversity in agriculture" is important in the context of the National Biodiversity Strategy. The indicator "agricultural land of high natural value" (HNV) is also part of the indicator set of the National Biodiversity Strategy with a concrete reference to the agricultural landscape. These areas include, for example, extensively used fields, species-rich dry grassland sites or fallows. As a rule, more animal and plant species are represented there that are not to be found in the "normal landscape". Landscape structural elements such as hedges, ponds, pits and terraces also offer a special habitat for flora and fauna and are therefore also included in the HNV areas.
In addition to the set of indicators of the National Biodiversity Strategy, there are a number of other indicators with relevance for biodiversity in agricultural landscapes that are recorded by various bodies and using various methods in Germany.
