Regional Landscape Park «Znesinnia» was declared an object of nature reserve fund of Ukraine by the decision of the Lviv Regional Council of People's Deputies. The park was created to preserve and recreate the unique natural and historical complex of the Znesinnia ridge and the adjacent territories of the ancient settlements of Znesinnia and Kryvchytsia. The territory of the Park belongs to the category of lands of nature protection, health, recreational and historical-cultural purpose. The Park has an area of 312.10 hectares. To regulate the impact of the urban environment and the formation of a single natural and architectural ensemble of the Park and adjacent areas, a protection zone of 473.61 hectares is allocated. The area of the Park together with the protection zone is 785.71 hectares. An organic-based spore preparation is used in the research. The research was conducted in the spring. To consolidate the effect and to minimize the risk of loss of positive dynamics, taking into account the negative succession changes observed earlier, it is recommended to re-inoculate during the growing season with mycorrhizal spore preparation of the soil of Mount Leva in RLP «Znesinnia».
