Abstract

In this study, we take an ecosystem approach to examine the degree of biological self-organization at the ecosystem level. An integrated set of indicators is derived from a theoretical framework and tested by field data froman ecosystem research project focusing on the Bornhoved Lake district in northern Germany. This field test is based on a comparison of the self-organized phenomena that comprise the carbon, water, and energy budgets of two adjacent edaphically and climatically similar ecosystems, that have vastly different levels of human interference-a crop field and a beech forest. fn terms of biomass storage, biologically incorporated nitrogen and phosphorus,species number, total ecosystem respiration per total biomass (qCO(2)), total ecosystem assimilation per available nutrients, and transpiration per total evapotranspiration, we found clear differences between the systems. Ecosystem surface temperature and R-n/K* were found to be of limited utility in characterizing the two systems. The study is rooted in the concept of ecological integrity, an influential idea at the interface of ecological and environmental debate that has acquired a number of different meanings. Among other interpretations, it can be viewed as a guiding principle for sustainable land use that aims at long-term protection of ecological life-supportsystems. Effective use of any interpretation of this concept requires a theoretically consistent and applicable set of indicators. Therefore, we alsodiscuss the integration of the indicator set and its potential use in monitoring programs.
