dc.abstract.en Benthic invertebrate-based indexes are commonly used as proxies for river health, especially river water quality. Scores of BMWP-PL index (a Polish equivalent of the British Biological Monitoring Working Party score system) were determined for 20 unmanaged and channelized cross-sections of the Biała River and compared with water quality and physical habitat parameters in the cross-sections. The two types of cross-sections clearly differed in the physical habitat conditions, whereas physico-chemical parameters of the river water mostly varied in the downstream direction. The number of recorded taxa ranged from 3 to 26 and the respective scores of the BMWP-PL index indicated the water to vary between high and poor quality. Since the analysed water quality was consistently high, the BMWP-PL scores were not related to physico-chemical parameters of the water but to physical habitat parameters, with the number of low-flow channels explaining the largest proportion of the variance in the index values. The lacking dependence on physico-chemical water parameters renders the BMWP-PL as indicator of the ecological integrity of rivers, related to their hydromorphological and physico-chemical characteristics, rather than of water quality. pl
