Bokoch V. Biotic productivity of forests of Carpathian National Nature Park and their dynamics

The analysis of dynamics of main mensurational indicators of stands of main forest forming species of Carpathian NNP is done. Researches of structure and total amount of phytomass of forests of Carpathian National Nature Park within forests departments, main forest forming species, age classes and groups of altitude above sea level are presented with using stratum method of estimation of phytomass components are made. Adapted and implemented methodology for calculating bioproductivity of stands by components of phytomass and depositing carbon was to find out their multifactorial dependencies on mensurational characteristics of stands, which are specified in the State forest inventory data. As the depending variable in modeling the dynamics of phytomass components of stands conversion factor was used (ratio of the mass of phytomass fraction (Mfr) to volume of trunk over bark (M). With using conversion factors was estimated depositing carbon in phytomass of Carpathian NPP.
