White sea shore plant communities in the Varzuga River Mouth (Tersky Bereg, Kola Peninsula).

摘要

A phytosociological survey of the White Sea coastal plant communities in the Varzuga River Mouth using the Braun-Blanquet approach is presented. The association Honckenyo-Elymetum arenariae is described from the edge of the sand beach. Halophilous vegetation is fragmented and ascribed to the Carex maritima-var. of Festuco-Caricetum glareosae Nordhagen 1954. The vegetation of the dunes belongs to the association Elymo-Festucetum arenariae, with Agrostis straminea-community stands in small depressions. The dune slacks are occupied by the association Gymnocoleo inflatae-Juncetum filiformis which is newly described. Coastal heath vegetation is represented by the association Arctostaphylo alpini-Empetretum hermaphroditi and Calluno-Cladinetum. Open stands of the Sphaerophorus globosus-Empetrum hermaphroditum plant community are situated on individual sand-blown sites.
