AU - Pijar, Katarzyna AU - Staszkiewicz, Karolina TI - Application of macrophytes in assessment and classification of ecological state of upland rivers and streams in south Poland, in accordance with requirements of the Water Framework Directive AB - In this paper an effort has been taken to bind usefulness of water plants – as bioindicators of running waters eutrophication – with observations concerning influence of modifications in hydromorphology of watercourses on species diversity of macrophytes occurring in them. Research was conducted in four upland rivers and streams located in south Poland. Research results indicate that slight anthropogenic modifications in river channels cause increase of macrophyte species diversity in relation to natural conditions, but advanced modifications cause ecological degradation of watercourses below the level of initial stage. Results of assessment also indicate that there is a need of developing the Macrophyte Method of River Assessment in direction of immediate connections between the value of Macrophyte River Index and physicochemical state of surface waters VL - 2012 IS - Środowisko Zeszyt 2-Ś (23) 2012 PY - 2012 SN - 0011-4561 C1 - 2353-737X SP - 17 EP - 32 DO - 10.4467/2353737XCT.14.049.1826 UR - https://ejournals.eu/czasopismo/czasopismo-techniczne/artykul/application-of-macrophytes-in-assessment-and-classification-of-ecological-state-of-upland-rivers-and-streams-in-south-poland-in-accordance-with-requirements-of-the-water-framework-directive KW - ecological state KW - macrophytes KW - surface water quality KW - Water Framework Directive KW - upland watercourses
