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.

AbstractExploring features of wood anatomy associated with fire scars found on fossil tree trunks is likely to increase our knowledge of the environmental and ecological processes that occurred in ancient forests and of the role of fire as an evolutionary force. In Petrified Forest National Park, Arizona, where Late Triassic fossil trees are exposed, we found 13 examples of fossil logs with external features resembling modern fire scars. One specimen with the unambiguous external features of a fire scar was collected for analysis of its fossilized wood. A light-colored band composed of compressed and distorted tracheids was associated with the scarring event. Cell lumen diameter and cell wall thickness in the pre-scarring fossilized wood show a response similar to that described in modern trees experiencing drought conditions. Tracheids in the post-scarring wood are initially smaller, and then become larger than average following a recovery period, as is often observed in modern conifers following fire. The responses in external morphology and wood anatomy to drought and fire were similar to those of some modern trees and support the view that some forests may have experienced conditions favoring the evolution of fire-adapted traits for more than 200 million years.
