Landscape Bionomics Ingegnoli (Istituto della Enciclopedia Italiana Treccani, vol. IV, XXI Secolo, Roma, pp 23–33, 2010; Thermodynamics—systems in equilibrium and non-equilibrium, InTech, pp 139–172, 2011a; Bionomia del paesaggio. L’ecologia del paesaggio biologico-integrata per la formazione di un “medico” dei sistemi ecologici, Springer-Verlag, Milano, pp XX + 340, 2011b) recognises the landscape as a living entity, within which vegetation components play the most important role in the structure and functions of this very complex system. The evaluation of the bionomic state of natural and human vegetation is essential to check landscape pathology. The evaluation of the biological territorial capacity of vegetation [BTC, sensu Ingegnoli (Landscape ecology: a widening foundation, Springer-Verlag, Berlin, New York, 2002; Israel J Plant Sci 53:155–166, 2005] represents a good step towards advance, because of the similarity with the concept of metastability. However, the BTC index is not always useful to check exhaustively the bionomic state of a vegetation formation (i.e. vegetation efficiency in the landscape). That is why a new bionomic index, relating the maturity level of a vegetation coenosis to its bionomic quality (bQ), is proposed in this paper. This function, named “concise bionomic state” (CBSt), is available for being applied to many theoretical and practical studies.
