Conteúdo: 	Significant limitations of the ecosystem concept as a framework for ecology and natural resource management are discussed giving particular emphasis to the recent development of 'systems ecology'. A multivariate analysis of shrub-steppe plant communities of the Western Riverina of New South Wales is used as an example to demonstrate the restrictions of mathematical approaches for obtaining comprehensive ecological understanding. The ecosystem concept and associated methods over- emphasise parameters and processes that are easy to express or describe in numerical terms; yet the many characteristics of living systems that are either difficult or impossible to quantify or predict are ignored. Since current natural resource management is based on the ecosystem concept, it presupposes a far higher degree of predictive sucess than the intrinsic properties of living systems allow. The ecological management of living systems demands a comprehensive understanding of ecology and its sole valid foundation of evolutionary biology. Based on this proper conceptual framework, natural resource management must aim at safeguarding and promoting the continuing successful functioning of the evolutionary process and its products. A new definition of natural resource management is proposed to clearly point up the dualism of selection processes now operating in living systems: ecological management is the substitution of manipulated selection for natural selection processes in the biosphere.
