Abstract

The Pavlovsk Park of St. Petersburg is divided into 7 natural landscapes. They differ in the species composition of plantations and soil conditions. With the use of a key to plants we identified tree and shrub species in plantations of all park landscapes and determined species diversity of its stands with the help of various indices. The composition community in the landscapes of the park is relatively similar, with the dominance of forest species: Picea excelsa, Betula pubescens, Pinus sylvestris, European white birch and Populus tremula. These species were predominant during the park formation from a coniferous forest. At present, there is a change of coniferous species to broad-leaved species due to the anthropogenic effects on the biocenosis. A part of coniferous and small-leaved species was sawn up to make logs for the fire during the Great Patriotic War. The landscape felling was carried out for the formation of half open landscapes and exteriors. Quercus pedunculata and Tilia cor-data were planted in the felled areas. The number of plants in each landscape varies, depending on the square footage and stand density. Plantings are also distinguished by the number of species, age structure and sanitary state. Architectural and landscape plant compositions are represented by arborous large forests, separated forest stands and single trees.
