The present Article discusses recent successive processes dynamics in naturally
renovated secondary phytocenosis of landslided territories of rich and diverse
mountainous Adjara region. The comparative analysis of soil cover productivity level,
floristic composition and cenotic structure of secondary phytocenosis and alongside
slopes are made for identification of successive serial stage.
The researches show that at lifeless substrates of landslided slopes, phytocenotic
structure is formed with gradual establishment of cenotic inter-relations between
species, in parallel with growing the coniferous plants, which is differentiated in
terraces. A certain system of natural renovation is created, soil-creation processes are
active. The secondary phytocenosis have developed at traces of chestnut copses, beech
forests and oak forests of landslided mixed-leafy forest formations, where these species
of plants are not met and the renovation of these species is not noted as well. The
formation of secondary natural phytocenosis took quiet short period (30 years) in local
natural climatic conditions, at landslided areas but the prospect for development of
monoclimax ecosystems (forests before landslide) is less supposable in nearest future.
pH of renovated forest soil is transitive from average acidity to weak acidity. The soil
is full of movable CaO MgO PO K O 2 5 2 , , , concentrations and is poor in humus and
nitrogen. Natural mixed-leafy forest soil reaction is near to natural. The concentrations
of movable calcium are 1-2 times more and movable Magnesium 4 times more in it.
Besides, general humus concentration is 1,75 % more and general nitrogen is 0,232%
more which indicates at high productivity level of these soils. Natural mixed-leafy
forest soil is characterised by much higher productivity (area reaction, concentrations of
movable forms of nutritious elements, Humus and Nitrogen), rather than pine-forest
soil, which makes reflect at special compositions of renovated forest and natural
renovations process as well.
