The geobiocenological research in the natural forest ecosystems of the Carpathian protected areas

In the first half of the 20th century the Czech botanist and forest ecologist Professor Zlatnik established an extensive system of research plots in virgin forest in Eastern Carpathians on former Subcarpathian Ruthenia. The research results of this research plots was published in 1938 (Zlatnik, 1938). In 1991 the research team of the Tatry National Park Administration leaded by Ivan Voloscuk established on the basis of the Zlatnik's plots in the territory of the Carpathian Biosphere Reserve a series of new reserach plots in the Pop Ivan Marmaroshskyi region, and in 1992 this research team established a new reserach plots in the flyss region of Polonina Krasna and in the flyss region of Gorgany. The research plots in the crystaline massif belong to the spruce-beech-fir and spruce vegetation belts. The research plots in the flyss massif of the Polonina Krasna and Gorgany belong to the beech, fir-beech and spruce vegetation belts. The total production (volume) of dendromass depends on evolutionary (developmental) stages and phases of the natural forests according to Korpel sense (Korpel, 1989). On the basis of the literature and own experimental knowledges were elaborated the production characteristics of the developmental stages and phases of the Carpathian virgin forests. For the further ecological research in Carpathian forest ecosystems is needed consequentially locate the permanent research plots in the one developmental phase and stage. Average data description on the production, growth and structure of the virgin forests without consequentially differentiation of the developmental stages and phases do not possible of the scientific interpretation of the ecological prosesses in virgin forests. For the further biogeocenological reserach in Carpathian virgin forests it will be useful to establish an permanent ecological research network. International eco-logical research programme in Carpathians is required to aim on this permanent research network. Voloscuk named this network as "The Carpathian Long-term Ecological Reserach and Monitoring Network - CALTERMON" (Voloscuk, 1995). Geobiocenological research work in 1991 and 1992 in the described regions is a contribution on this idea
