Typological classification and the existing condition of artificially established sycamore maple and Norway maple stands in the protective forest belt

The study results on the typological classification of the artificially established sycamore maple and Norway maple stands included in the shelterbelt along the Belgrade-Zagreb“ highway are presented. The environmental conditions of the sycamore and Norway maple plantation have been typologically defined in specific typological entitities at the ecological level (ecological units). In this context, the specific site conditions were characterised and defined as: a) Forest of common oak (Tilio-Quercetum crassiusculae typicum) on leached chernozem, b) Forest of common oak (Tilio-Quercetum crassiusculae typicum) on moderately deep to deep calcareous chernozem, c) Forest of common oak (Tilio-Quercetum crassiusculae typicum) on shallow to moderately deep calcareous chernozem. The inter-relationship between sycamore maple and Norway maple regarding the ecological and coenological optimum differs within the above ecological units. The diversity reflects the sycamore and Norway maple bioecology and the site typology of the particular ecological units.
