The virgin forests of the Ukrainian Carpathians are unique ecosystems in which preserved natural, protected, recreational, historical and cultural objects. That is why a comprehensive study of the forest ecosystems of the Ukrainian Carpathians is needed in order to preserve these unique treasures of our country. The Ukrainian Carpathians are characterized in ecological, educational and scientific-cognitive aspects, as a significant number of objects and monuments of nature, history, architecture and culture are concentrated here. In the region under study, there is a well-developed network of nature reserve fund, the objects of which are basic for the organization of tourist activity. The importance of virgin forests as an ecological-educational and scientific-cognitive object of the Ukrainian Carpathians is revealed. The purpose of the research was to study the forests of the Ukrainian Carpathians, as an object of ecological, educational and cognitive perception. The object of the research was the forest ecosystems within the conservation areas of the Ukrainian Carpathians. The subject of the study was the consideration of forest ecosystems as an ecological-educational and scientific-cognitive object. To achieve this goal, the following tasks were set: to give a complete definition of the term “primaeval” forests and their varieties; to identify, establish distribution areas and forest areas in the Ukrainian Carpathians; to analyze their ecological-educational and scientific-cognitive functions. It is revealed that the centres of distribution of forest ecosystems in the Ukrainian Carpathians are nature conservation areas, namely: Carpathian Biosphere Reserve, Carpathian National Park, Uzhansky, Synevyr Verkhovyna, Cheremosky, Hutsulshchyna, Vyzhnytsya, Zacharovanyi Krai. It is stated that ecological-educational and scientific-cognitive objects in the region are natural undisturbed by the anthropogenic activity of the place. The best network of ecological-educational and scientific-educational trails is set up in the Carpathian Biosphere Reserve. The most popular are the eco-routes “To Goverla Mountain from Lazeshchyna”, “Kevelsky Forests to Petros”, “Beech Forests of Velyka Ugolka”, “To Sokolino Berdo”. It is revealed that the ecological-educational and scientific-cognitive potential of the forests of the Ukrainian Carpathians is special. The primaeval forests are widespread in the Ukrainian Carpathians, and their area is about 50 thousand hectares, and much of it requires identification. Forests have a special status in Ukraine and are strictly protected in nature reserves and perform ecological-educational and scientific-cognitive functions, since within them preserved natural, intact, virgin objects and also represent the cultural heritage of the region. Key words: Ukrainian Carpathians, virgin forests, quasi-virgin forests, ancient forests, ecological-educational and scientific-cognitive objects.

The paper deals the complex research of the biota xylotrophic ascomycetous fungi of forest ecosystems of the the seven of natural reserve funds of Ukrainian Carpathians: NNP "Synevyr", Carpathian NNP, NNP " Hutsul’shchyna", Uzhansky NNP, NNP "Skolivski Beskydy" , and Carpathian Biosphere Reserve and Nature Reserve " Gorgany" is represented. A taxonomic composition and comparative analysis of ecological and biological features of the ascomycetous fungi is determined. In total 406 taxa 389 in the rank species were recordered for the investigated region. All found species representing 190 genera, 66 families, 26 orders, 10 subclasses, 6 classes, subphylum Pezizomycotina, that belong phylum Ascomycota, and also anamorphic fungi incertae sedis Pezizomycotina.

AbstractThe aim of this work was to assess how forest ecosystems dominated by Norway spruce (Picea abies (L.) or European beech (Fagus sylvatica L.) affect snow water equivalent (SWE) in relation to aspect and elevation. The research plots were established in a small headwater watershed of the Hučava flow belonging to the Poľana Biosphere Reserve (Central Europe, Inner Western Carpathians). The SWE values in this watershed (approximately 580–1270 m a.s.l.) were monitored during the three winter seasons starting from 2012–2013 to 2014–2015. The results revealed high variability in SWE and in snow cover duration between the studied seasons. The spatial variability was significantly affected by the forest ecosystem, aspect and elevation. The seasonal mean SWE value was lower by about 50–60% in the spruce forests and by about 21–30% in the beech forests compared to the open areas (100%). Over the whole seasons, the whole watershed mean SWE value on the slopes with the northern aspect was mostly higher compared to the slopes with the southern aspect. The effect of aspect was significant mainly in the open areas and in the forests dominated by European beech during the ablation periods of every season. In the case of the sufficient snow cover, the mean SWE value always increased with elevation. The elevation gradient of SWE was steepest at the open areas of the watershed in the peaks of the winter seasons. The three-season mean value of SWE elevation gradient (per 100 m) at the time of snow accumulation peak was equal to 16 mm in the spruce forests, 20 mm in the beech forests and 26 mm in the open areas. The research revealed that SWE is significantly affected by the forest ecosystem whilst its effect is dependent on the occurrence of dominant deciduous or coniferous tree species. However, the effect of forests is closely related to topographic characteristics (aspect and elevation) of a locality.

High Diversity

Most of the features that are commonly attributed to typical tropical rain-forests, such as a preponderance of woody vegetation and species with leaves in the mesophyll size-class, tall slender trees with ‘flying buttress’ and unusually thin bark, multilayering of vegetation with abundance of epiphytes and stranglers, evergreenness, strong tendency to change in species composition in time and space, and high diversity of dominance, are plentifully displayed by the forests of the Silent Valley in southwestern India. A relatively high species-richness, remarkably thin bark of trees, and high total tree-basal area, indicate that the valley embodies a virgin forest and that conditions for growth are very favourable. Because of the terrain, heterogeneity in habitats is well marked.The proposed construction of a dam and large flooding reservoir threatens to bring about several undesirable alterations in the environment of the Silent Valley rain- and riparian forests, and the disturbances that would follow such construction and flooding would be highly detrimental to the diversity of the forests and to the complexity of their structure. Hence a plea is made for the setting aside forthwith of a proposed major ‘Silent Valley Biosphere Reserve’, which could safeguard a unique part of the world's genetical heritage and one of its most interesting complexes of natural ecosystems.
