The syntaxonomical diversity of pine forests of the Lapland reserve.

摘要

Plant communities of Scots pine (Pinus sylvestris) of the Lapland State Nature Reserve were subdivided into 6 associations. The main pine forest associations distinguished are as follows: Pinetum cladinosum -- lichen-rich pine forests on sandy soils; Pinetum cladinosum saxatilis -- lichen-rich pine stands on rocks; Pinetum empetroso-myrtillosum -- pine communities with dwarf shrubs and mesophytic mosses; Pinetum sphagnosum -- sphagnum-rich pine stands on wet soils with peat horizon. Two intermediate types are distinguished: Pinetum hylocomioso-cladinosum (on dry sandy soils) and Pinetum fruticulosum (on wet soils). The diversity of pine forest vegetation of the Lapland Nature Reserve is similar to that of the eastern part of the Kola Peninsula, Russia.
