Abstrakt: Despite the strategic importance and social orientation of the project to install the world's highest mountain gas pipeline to South Ossetia, the damage to the environment is great. In contrast to flat terrain, highland landscapes due to large-scale natural (landfalls, avalanches, mudflows, landslides, etc.) or anthropogenic (installation of oil and gas pipelines) negative impacts either not restored at all, due to the progressive influence of factors interventions, or the recovery takes decades. In high-mountain areas, soil destruction is accelerated due to developing sources of landslides and ravines, mudflows, creeps and collapses, active lateral infiltration of groundwater, leading to rapid dehydration of soil and biocenosis degradation. Neglecting the scientific basis for minimizing damage to the environment, the primacy of business over environmental consequences, the lack of fundamental and qualified expertise of projects relating to interference with the natural environment, the legislative vulnerability of ecological systems have become commonplace and have a very steady tendency to take root. The result of consumer attitudes towards ecosystems is estimated by the example of these works by extensive disafforest, deep cutting of extended slope intervals at high mountains and, finally, significant deviations from the original project. At the same time, there are no works on recultivation, which, however, are doomed to failure in the existing orographic and seismological conditions of the Dzuarikau-Tskhinval gas pipeline route. The route of the Dzuarikau-Tskhinval gas pipeline enters the Kassar (valley of the Ardon River) gorge near the Tamiysk resort and then it cuts through both slopes of the Ardon River to Zaramag HPP, and then passes through the picturesque valleys of the Mamikhdon and Zemegendon Rivers, where the gross impact on nature is most clearly observed.
