English Abstract
A demand for standard-setting procedures in terrestrial ecosystems is identified in addition to existing standard-setting procedures for aquatic ecosystems. In this report a comprehensive method for environmental quality assessment is summarized, differentiated for ecodistrict types. These large scale ecosystem types may fulfill various land use functions, including nature conservation. Two quality levels, as distinguished in environmental policy (National Environmental Policy Plan), have been adopted as guidelines: General and Specific Environmental Quality (AMK and BMK respectively). The latter has been defined for nature conservation only. Quality assessment of entire ecosystems concerns the measurement of the present state and comparison with the desired state. The desired state is explicited in terms of 'ecological quality standards'. The results are presented in AMOEBE-like figures, with for each parameter the circle as standard, and the present quality as a percentage of the radius.
