Modern approaches to the development of nature management are focused on the formation of a system of sustainable development of regions. Forest territories act as an edifier, which has a global impact on the state of all ecosystems under the conditions of increasing anthropogenic pressure, reducing biodiversity and reducing the productivity of natural ecosystems When creating the ecological frameworks of territories, various research methods are proposed: information-analytical, comparative-geographical, the method of route survey of the territory, and cartographic. The reduction in the area of natural ecosystems leads to a significant reduction in the biodiversity of the most diverse groups of organisms. The extinction and significant reduction of species (very often even background for certain territories) leads to a decrease in genetic biodiversity, and, as a consequence, a disruption to evolutionary processes.
