Opis:
Scots pine stands are the most important forest type in Poland and the differentiation of the natural vegetation in these forests is well known. However, the intensive utilization causes the formation of the secondary communities, so that further studies of the vegetation diversity should be carried out with taking into consideration stand age and homogeneity of site conditions. The aim of this work is to assess the diversification of plant communities across the gradient of tree stand age. Scots pine stands on oligotrophic sites of the Przymuszewo Forest District were examined with dividing into six age classes ( 10, 11−20, 21−40, 41−60, 61−80, 81−120 years old). Numerical analysis allowed to differ 4 plant communities: non−forest community of Placynthiella−Cladonia sp. div. related to young stands before crown closure ( 10 years old), secondary forest community of Pinus sylvestris−Cladonia subulata related to young stands just after crown closure (11−20 years), forest communities of Leucobryo−Pinetum variant with Cladonia and typical variant – both related to stands older than 20 years. The identified communities differ in terms of species richness and vertical structure, but they are repetitive combinations of species which can be classified within hierarchical syntaxonomical system. They show common features with the communities of south−western Poland, but differ from plant communities of managed Scots pine forest in the continental part.

Opis:
Clear−cutting impacts site conditions seriously. However, in nutrient−poor sites the effects of stand removal can be minor than in nutrient−rich sites. The aim of this work was to assess whether the clear−cut can improve species diversity of ground Cladonia species, which decline has been observed in forest communities. In stands of different age classes (≤10, 11−20, 21−40, 41−60, 61−80, ≥81 years) in the Przymuszewo Forest District (northern Poland) ground Cladonia species and their cover were recorded on research plots (10×15 m). A total of 24 species were identified in the study area. There were more Cladonia species and they were more abundant in young stands (<20 years old) than in stands older than 60 years. Nine species are significantly more frequent and demonstrated high fidelity in young stands and only one was characteristic for old stands. Composition of Cladonia species depended primarily on stand age and subsequently on canopy or bryophyte cover. In nutrient−poor sites clear−cutting is favourable for Cladonia species diversity.
