Ground water as the main factor differentiating the natural vegetion in a landscape phytocomplex ("Grabowy" range in the Kampinos Forest Complex)

Abstract

In the period 1973-1975 the depth of the ground water level and the moisture of the surface soil layer were investigated in various plant communities of the "Grabowy" range in the Kampinos Forest Complex (central Poland). The studies included a fragment of a landscape phytocomplex within which eight types of forest plant communities were distinguished. It was found that the plant communities change parallelly to the differences in the soil-water conditions (ground water level, physical properties and moisture of soils) in space.
