Vegetation of the open shore region

Eastern subregion. The littoral zones of the Uksunlahti and Lunkulanlahti bays, the eastern shore of the Mantsinsaari island are dominated by reed communities, their strips occasionally reaching 150-200 m (Raspopov, 1985). Many bays and islands of the eastern subregion get overgrown in a similar way.

Aggregations of Phragmites australis, Potamogeton perfoliatum andP. gramineum occur in the rocky littoral (tidal zone of the shore). In windless littoral areas, in bay tops aggregations of Phragmites australis, Potamogeton perfoliatum and P. gramineum are joined by Carex acuta and Scolochloe festucacea.

The breaker-impact sandy littoral zone is free of vegetation. Windless sandy areas are inhabited by Carex acuta, Scolochloe festucacea, Alisma plantago-aquatica, Eleocharis palustris. The north-western part of the Andrusovskaya bay is the only habitat of Scirpus lacustris, and home to a rare community with Littorella uniflora.

Plant communities associated with the Baltic coast and shores of large lakes stretch along the sandy beaches of the eastern shore to the north of the Svir river mouth. The main species forming these communities are European dune grass (Leymus arenarius) and beach pea (Lathyrus maritimus). These communities include also a willow species (Salix acutifolia) which had often been used to stabilize bank sands. Therefore, many flora researchers doubt its natural provenance on the Ladoga shores (Reviews..., 1982).

The western subregion. The western subregion of the open shore region is little overgrown. The leading role in the process of overgrowing belongs to common reed (Phragmites australis). The area of Potamogeton perfoliatum and P. gramineum is insignificant. Reed is adjoined by Scolochloe festucacea communities.

Dunes form in the sandy beaches. Communities made up of Calamagrostis epigeios and Leymus arenarius and isolated pine trees are common on the dunes. The sand by the shore is occupied by communities with the same species, as well as Festuca sabulosa, Lathyrus maritimus, Equisetum arvense. Juncus balticus occurs by the water and in small depression.

The shore to the north grows heavily bouldery, sometimes rocky. The water-edge here is approached by forests: bilberry, speckled alder with Aegopodium podagraria or meadowsweet (Filipendula ulmaria), purple small-reed (Calamagrostis canescens) spruce stands; in moister places - birch stands.
