In 2024, a comprehensive analysis of the structure and state of the terrestrial ecosystems in the Tesiin-Gol Bulnain-Nuru National Park (Mongolia) was performed using the geoinformation mapping methods. Based on field route mapping, interpretation of modern satellite images (Landsat), expert assessments and data analysis, the ecosystems were grouped into 38 units and the degree of their disturbance was estimated. Mountain ecosystems account for about two-thirds of the study area. Tundra and yernik high-mountain ecosystems make up approximately 11% and forests over one-fifth of the territory. Shrub cryogenic ecosystems cover 10%, cryophyte (alpine) meadows 11%, and cryophyte steppes 5% of the area. Forest-steppe ecosystems occupy 11%, while steppe ecosystems more than 29% of the park’s territory. Among the driving factors that destroy the natural ecosystems of the Tesiin-Gol Bulnain-Nuru National Park are uncontrolled grazing, forest fires, pests, and logging. Around 60% of the ecosystem area is in a satisfactory or slightly disturbed condition, 25% is moderately degraded, over 12% severely disturbed, and 3% is extremely severely disturbed. This study demonstrates the effectiveness of the integrated approach to assessing the dynamics of natural ecosystems susceptible to anthropogenic impacts and provides a scientific basis for developing measures on biodiversity conservation and sustainable use of natural resources.
