Лесная растительность островов озера Каменное (Карелия)

Abstract

The boreal forest vegetation was studied on small islands scattered on the Kamennoe Lake, Kostamus strict nature reserve (Republic of Karelia). Lists of floristic notes were obtained for every island including bryophytes. Vegetation relevés were made on study plots of standard size (20 × 20 m). The data were compared with these representing plant cover of inter-mire mineral islets in Juortanansalo, eastern Finland. Mesic pine forests of Vaccinium-type are typical for the most of studied islands. Semi-dry pine forests of Empetrum-Vaccinium vitis-idaea can be found rarely. Vegetation data on mire islets represent the mesic spruce forests of Vaccinium type. Due to preservation regime vegetation dynamics goes in the direction of spruce forest recovering after disturbances caused by man and fires.
