Résumé :	According to Article 16 of Regulation (EC) No. 746/96 all member states of the EC are required to evaluate their agri-environment programmes to ascertain the environmental and socio-economic impacts. Analysing these impacts is a frontier topic for scientists with much research in progress. This article contributes to this research agenda in developing and applying a scheme for the evaluation of agri-environment measures from an ecological and economic point of view. The agri-environment programmes of all German federal states are systematically compared with regard to their impacts on biotic resources. Expert opinions obtained from a Delphi study serve as indicators for the ecological consequences of the programmes. Two measures for the ecological cost effectiveness of the agri-environment programmes are derived and applied. For the economic evaluation the cost effectiveness ratio and the benefit cost ratio of the programmes are calculated. Thus, this article presents an example for an integrated ecological–economical assessment of policy measures. It is shown that with respect to the protection of biotic resources by agri-environment programmes, no contradiction between ecology and economics exists in Germany. Improved biotic resource conservation is also economically advantageous.

Résumé :	This article deals with the interrelation of ecological and economic aspects through the use of indicators. Two aspects are painted out: the first being the measurement of the economic value of ecological services, and the second being the integration of economic aspects into comprehensive indicator systems. The measurement of the economic value provides a means of determining consumer-orientated values of landscapes and bio-diversity issues. This measurement, however, is viewed critically by some, especially in nature conservancy circles. For them the intrinsic values of a landscape, which cannot be measured in economic terms, play the central role in the assessment of landscapes [Oekonomische Bewertungsgrundlagen und die Grenzen einer ‘Monetarisierung’ der Natur. In: Theobald, W. (Ed.), Integrative Umweltbewertung. Springer, Berlin, Heidelberg, pp.95–117]. On the other hand, Braeuers [Money as an indicator: to make use of economic evaluation for biodiversity conservation. In: Buechs, W. (Ed.), Biotic Indicators for Biodiversity and Sustainable Agriculture. Agric. Ecosys. Environ.], whose article presents an overview of current economic assessment methods, provides an alternate point of view. Braeuer [Money as an indicator: to make use of economic evaluation for biodiversity conservation. In: Buechs, W. (Ed.), Biotic Indicators for Biodiversity and Sustainable Agriculture. Agric. Ecosyst. Environ.] argues that through the inclusion of monetary values into the assessment process the whole issue can remain on a factual level. The article by Gerowitt et al. [Rewards for ecological goods—requirements and perspectives for agricultural land use. In: Buechs, W. (Ed.), Biotic Indicators for Biodiversity and Sustainable Agriculture. Agric. Ecosyst. Environ.] even goes further and suggests that a market oriented system be implemented for environmental goods. In contrast to the subjective measurement of economic value, land use models are based on “objective” expertise. Aim of the articles in this sector is to analyse the enhancement of scientific models by economic aspects. These models would then be used to verify the feasibility of ecological motivated land use claims. The results would form the basis for political decision making by a society. The model of Meyer-Aurich and Zander [Consideration of biotic environmental quality targets in agricultural land use—a case study from the biosphere reserve Schorfheide-Chorin. In: Buechs, W. (Ed.), Biotic Indicators for Biodiversity and Sustainable Agriculture. Agric. Ecosyst. Environ.] reviews land use decision making on the operational level, while the model of Herrmann et al. [Threshold values for nature protection areas as indicators for bio-diversity—a regional evaluation of economic and ecological consequences. In: Buechs, W. (Ed.), Biotic Indicators for Biodiversity and Sustainable Agriculture. Agric. Ecosyst. Environ.] reviews decision making at a regional level. The concluding article by Kantelhardt et al. [Is there a reliable correlation between hedgerow density and agricultural site conditions? In: Buechs, W. (Ed.), Biotic Indicators for Biodiversity and Sustainable Agriculture. Agric. Ecosyst. Environ.] attempts to correlate selected different economic and ecological indicators. The key issue here being how farmers can be compensated for the conservation and preservation of landscapes.

Résumé :	Referring to the agricultural history in Central Europe determinants of floristic diversity at the habitat scale and the decline in diversity over the last few decades are described. In this context the preservation of floristic diversity is stressed to be one important goal of modern, multifunctional agricultural land use. To reach this goal indicators of diversity are useful tools to evaluate the effects management practices have on floristic diversity in agro-ecosystems. However, “key indicators” that allow an easy assessment and evaluation of diversity are still lacking. Potentially, indicators of biodiversity measures at the habitat scale can be developed from a large number of parameters. An attempt to classify parameters into three major types of indicators and requirements indicators have to meet are presented. Based on the contributions in this special issue and further references recent approaches to indicate floristic diversity at the habitat scale in agricultural landscapes of Central Europe are summarized and discussed. It is concluded that further research should focus on the validation of existing approaches and their integration into a comprehensive set of indicators and on the development of standardized modes of collection for data.
