The paper is an attempt to evaluate the degree of naturalness of the vascular plants flora of 24 fishponds complexes using numerical coefficients of: modernization, rarity, floristic individuality and naturalness. The vascular plants flora recorded in the areas under study consists of 584 species. The high degree of naturalness is shown by the numerical coefficients used for the analysis, which is confirmed by an important role of indicator species and species characteristic for natural and semi-natural vegetation connected with consecutive stages of succession on water bodies. It is also confirmed by high percentage of protected and endangered species.
