    Opis:
    Fires that are one of the most classic disturbance of plant communities have had a great impact on the development of Scots pine communities. Restoration of vegetation disturbed by fire in this type of community starts almost immediately after disturbance. The intensity of fire significantly influences the future composition of vascular plant species and also the rate of change. The aim of the study was to describe the effect of intensity of the surface fire on the forest floor vegetation response and to preliminary attempt to characterize the syndynamic processes occurring after the disturbance. The research was conducted in Scots pine forest Peucedano−Pinetum in the Kampinoski National Park (central Poland). We established 45 permanent study plots, including 17 not burnt (control) and 28 burnt ones. Each plot covered area of 100 m². On each plot at first we separated the areas which were not burnt, surface burnt and characterized by complete burnout of the organic horizon of the soil. Than we measured the thickness of this horizon. Additionally the volume of organic matter burnt within each plot was calculated. Vegetation was sampled using Londo scale in the year of fire (2015) and the year after (2016). We used DCA ordination and UPGMA classification methods. Recorded species were divided into forest and non−forest groups and additionally for trees and shrubs, and the others, containing dwarf shrub, herb, bryophyte and lichen species. The linear regression method was used to estimate the relationship between measured parameters, vegetation change and changes in the species richness of distinguished groups. Two processes of vegetation reaction were observed. The first was classified as regeneration and occurred within surface burnt plots. Its characteristic feature included the higher increase in forest species richness than in case of non−forest species. The other process was defined as secondary succession alike. It occurred on plots with highest burnout of soil organic matter horizon. The increase of richness of non−forest species predominated within it. The change between two processes is smooth and depends on the participation of area with complete burnout of soil organic horizon within plot. The results show, that more than one process of recovery of community can occur in the same site and it depends especially on the proportion of soil organic horizon area burnout.

    Opis:
    Cladonio−Pinetum Juraszek 1927 forest is protected in Europe as the Natura 2000 habitat. Nowadays its naturalness is often considered to be doubtful. In spite of the many research, the knowledge about ecology and dynamics of this community is still insufficient. The aim of the research is to define the stability of the community within ‘Bory Tucholskie' National Park. The site is located in the area of the best developed patches of the habitat, in north−western Poland. Two datasets of relevés were used. The first comes from published data and includes 123 relevés made in year 2000. The other comes from own fieldworks performed in 2014. Due to the high homogeneity of geology and soils of the study site, repeated chronosequence method could be used to compare both datasets. The information about herb and moss layers of all relevés was compared using DCA method. The change in community was measured as a shift in the position within the main gradient of DCA over 14−year period. It was calculated for 122 pairs of relevés. Than the model of the speed of community change was computed for the main gradient. We used two methods of calculation of duration of the lichen−rich pine forests. The first was based on the calculated ranges of distinguished associations and the other used the model of cover of species connected to Cladonio−Pinetum forest. As the speed of community change in the gradient and the distance between distinguished communities were known, the time of community duration could be computed. According to obtained results, Cladonia−Scots pine forest (Cladonio−Pinetum) and lichen rich fresh pine forest (Leucobryo−Pinetum with Cladonia) of ‘Bory Tucholskie' National Park will last for 64−109 years. This result shows, that the considered Natura 2000 habitat is unstable. It is the possible development stage within managed forest stands and active conservation is necessary where its preservation is needed.
