The aim of this study is to present the differentiation of plant communities and their typical habitats found within groundwater-fed wetland complexes in north-western Poland. The study objects were 18 valley wetland complexes consisting entirely or in major part objects consisted of 81 syntaxa of water-, spring-, mire-, meadow-, willlo carr- and alderwood communities, as well as of 4 syntaxa of the mesophytic forests. The expression of environmental conditions in the groundwater-fed communities has been analysed on the basis of Ellenberg's indicator values and the occurrence of protected and rare species. A negative correlation has been found between the occurrence of rare species and trophy index
