FLORISTIC RICHNESS AND DENSITY OF SALTMARSH COMMUNITIES DOMINATED BY TRIGLOCHIN MARITIMA L. (JUNCAGINACEAE) ON THE NORTHERN SEAS COASTS

Abstract

The article presents the results of studying of the floral richness and density of communities dominated by the circumboreal temperate Arctic species Triglochin maritima L. (fam. Juncaginaceae). On the tidal zone of the western coast of the White sea in the direction from the lowland to the level of the low tide the geobotanical descriptions of plant communities on the model transects were made. The ecological characteristics of habitats, including geomorphic shore type, wave exposure and the mechanical composition of the substrate were given. It is revealed that various indicators of the geomorphological structure of the coast of the Bay effect on the characteristics and features of the floristic richness and density in the saltmarsh communities in these biotopes
