Abstract | Vegetation- environment relations were investigated in rare European inland saline areas. In the natural saline areas only four communities were found: the Puccinellia distans- Spergularia marina community, the Triglochin maritima community, the Scirpus maritimus community and the Glaux maritima-Potentilla anserina-Agrostis stolonifera community. After CCA and CVA analyses, the salinity expressed as the electrical conductivity of saturated extract (ECe) was identified as the main factor decisive for the vegetation pattern. However, different sets of soil properties influence the distribution pattern of species and communities. In the species-environment relations Cl- concentrations, N-tot, ECe, K+, pH and SO42- content of the soil level 0-25 cm are significant, whereas EC,, moisture, SO42- and Ca2+/Na+ ratio are significant in the community-environment relations. At the highest salinity the optimum of obligatory halophyte Salicornia europaea was found. Aster tripolium, Triglocbin maritima and Lotus tenuis were associated with high EC, and nitrogen content. The other halophytes: Spergularia marina, Atriplex hastata var. salina and Puccinellia distans reached their optima on the soils with a relatively high salinity level and SO42- content. Considering the community- environment relations, the strongest correlation with the salinity is displayed by the Salicornia europaea community. The Aster tripolium community, the Triglocbin maritima community and the Scirpus maritimus community are also associated with high soil moisture. The occurrence of the Puccinellia distans-Salicornia europaea-Spergularia marina community is connected with SO42- content in the soil. |
