Abstract

The modern composition and structure of the forest vegetation of the Naliboksky Nature Reserve is strongly influenced by drainage channels. As a result of this influence, difficulties arise in determining the types of forests, especially pine forests.

The floral composition and structure of wetlands depends on the degree of drainage and depth of peat deposits. In this territory, among the forests of the Pinus sylvestris formation, five types of phytocenoses have been identified for which an accurate geobotonic characteristic is given.

The analysis carried out on the basis of the floristic classification of Y. Brown-Blanke showed that, depending on the degree of drainage, the depth of the peat deposit and the underlying rock in the drained pine divade, five groups of phytocenoses (phytocenones) were identified. The first group is shrubbysphagnum pine forests, the second group is blueberry-ledum pine forests. The third is fern-long-moss pine forests. The fourth – raspberry-blueberry pine forests, the fifth-raspberry-sphagnum-blueberry pine forests. A detailed geobotanical characteristic is given for each group.
