The analysis was based on the results of the river survey carried out in the UK and Northern Ireland in the period 1995-2002 where 288 relevès were described. A field assessment was undertaken according to the phytosociological method by Braun-Blanquet approach. Common types of plant communities were analysed, which were classified as 12 phytosociological associations. These represent a wide ecological range. The environmental requirements were classified basing on the 10 variables, which reflect different kinds of geographical conditions as geographical, landscape, geology, land use of the watershed and water quality. The aim of the study was presenting usefulness of canonical variate analysis for estimating environmental requirements of plant communities. The position of different vegetation types was shown in the space of canonical variates. Canonical variates appeared useful for detecting ecological needs of vegetation in the multivariate matrix.
