Abstract

This article explains the necessity of creating the Orilskyi National Natural Park .A national park is a universal and one of the most efficient forms of organizing nature reserves in the region. According to all criteria, the studied territory deserves the status of national park (according to the IUCN international classification of nature reserve territories – II category (“national parks”).  We have analyzed the historical preconditions for creating a park and highlighted the significance of the first scientific grounding for this proposal developed by the non-governmental organization “Ecological-tourist union “Orlan”. The problems of creating the Orilskyi national park are considered here in the context of recognizing the geological environment as an important component of the environment, which must be protected and maintained since objects of geological heritage are no less important than any other component of the nature reserve fund (NRF).  We have proved the necessity of conducting geological and geomorphological researches for the project, studying not only geologically essential objects of the NRF, but also objects, which despite being not significantly outcropped, are characterized by an interesting and unique history of geological development, peculiar manifestations of different geological processes, including volcanism, traces of ancient glacial epochs, erosive and accumulating effect of river processes, deluvial, proluvial, colluvial  and other processes on slopes, peculiarities of sedimentogenesis, imprinted in rocks of different lithological compounds, saturation of rocks with fossil fauna and flora, significance in understanding the secrets of past geological periods, etc. We have found and analyzed peculiarities of tectonics and neotectonics of the projected national park, which have formed the deep structure of the region and peculiarities of the current landscape . We have defined clear patterns in the relationship between biodiversity and geodiversity. Their unified relationship defines the natural value of any territory and its potential as a tourist attraction. We have identified the stratigraphic sequence of the geological formations which form the territory of the park from Precambrian to Holocene rocks, and describe in brief each of the identified stratigraphic units. This article presents for the first time the significance of the Orilskyi National Park as an important natural nucleus of an ecosystem of national significance – it is situated on the crossroad of two of the most important transnational wildlife corridors of the Pan-European Ecosystem – Dniprovskyi meridional and Ukrainian steppe latitudinal corridors, and also is the main part of the interregional conjunction of territory between left bank Naddniprianskyi Forest-Steppe and Steppe, and between the basins of the Dnipro and Siverskyi Donets.
