Opis:: Experimental data on carbon concentration in woody plant species biomass are very scarce and value of 50% of dry biomass is widely accepted in carbon storage modeling. On the other hand, some studies have proved that the carbon concentration in woody species biomass is variable and depends on the component. Thus, the main goal of the study was to determine carbon concentration in biomass of 7 understory shrub species (basing on 282 individuals): Corylus avellana, Prunus padus, P. serotina, Frangula alnus, Sambucus nigra, Cornus sanguinea and Sorbus aucuparia as well as to analyze variability of carbon concentration among shrub species and biomass components. Carbon concentration was analyzed for leaves, fruits, branches, stemwood, stembark, coarse and fine roots. Our study revealed that the mean carbon concentration in biomass of all species studied was 47.7%. We found statistically significant differences in carbon concentration among the shrub species studied in all biomass components. The mean value for particular species was as follows: Prunus serotina – 47.5%, P. padus – 47.6%, Frangula alnus – 47.7%, Sambucus nigra – 47.7%, Corylus avellana – 47.8%, Cornus sanguinea – 47.8% and Sorbus aucuparia – 47.8%. Additionally, we found statistically significant differences in carbon concentration among biomass components within the species studied. The mean carbon concentration in fruit biomass was 46.2%, in fine roots – 47.0%, in leaves – 47.2%, in coarse roots – 47.7%, in branches – 47.9%, in stemwood – 48.5% and in stembark – 48.6%. The variability of carbon concentration in fruit, branches and leaves biomass was higher than in the remaining biomass components. The variability of carbon concentration in biomass of woody species should be considered in carbon storage modeling in forest ecosystems.

Opis:: Managed forests are likely to be exposed to uncontrolled, spontaneous spread of alien/invasive species as a result of a frequently conscious introduction of alien species to forests in order to achieve economic gains. Unfortunately, we still lack data on the intensity of such invasions to forests on a larger scale. The aim of the paper is to provide a detailed qualitative and quantitative description of the existing regeneration of tree species, particularly the alien ones, and to determine the impact of selected factors on the regeneration of introduced species. The research was carried out in a mixed coniferous forest habitat in the "Uroczysko Główne". Particular focus was on the regeneration of alien species. Eight tree species were found to be regenerating naturally on the examined plots of which two were alien species. The scale of occurrence of alien species in comparison with native ones, particularly the black cherry, may now become a problem. Alien species accounted for nearly 25% of all tree species regeneration in the examined area and were noted in over half of the plots. It can therefore be said that the conditions occurring in the southern complex of the Niepołomice Forest have a great impact on tree regeneration and may favour spontaneous spread of alien species. The research helped to quantified and qualified the intensity of forest colonisation by the two most frequently occurring alien species.
