Abstract
Despite the abundance of visual data, the influence of hydrological and hydrochemical factors on the phytocenoses of the coastal vegetation of the White and Barents Seas has been poorly studied. The article uses non-metric scaling to demonstrate that the coastal vegetation communities are heterogeneous and tend to be associated with specific habitats based on their composition and structure. The coastal vegetation communities are influenced by a complex of factors related to the aquatic environment. Tides, storm surges, salinity, and pH levels have the greatest impact on the formation of coastal vegetation. Of these, tides and storm surges are the leading factors in the formation of phytocenoses of different types of marshes. Surfing has a significant impact on the formation of beach plant communities. The author’s classification of hydrological and hydrochemical factors affecting coastal phytocenoses is presented.
