The study of the spatial organization of geosystems is the most promising problem in the study of geodynamically active territories, which include the western macrosclope of the Barguzin ridge. The research area is difficult to access, so it is an urgent task to identify the features of the spatial organization of geosystems. It is important to know how the development of geosystems took place, what relationships exist between their components and the directions of their further change. Within the western macroslope of the Barguzin ridge there is a high diversity of relict and rare species of plants. The most ancient geological rocks that belong to the lower Proterozoic are developed here. A table of paleoreconstructions of the territory during the late Cenozoic is given, which reflects the features of the tectonic situation, climate changes, and the corresponding vegetation cover for each period under consideration. Paleogeographic analysis, taking into account the current spatial organization of geosystems, allowed us to identify relict species included in the structure of the vegetation cover, as well as their association with certain rocks, tectonic faults, which have a high warming up by endogenous heat. Such neotectonic activity is manifested in places of discontinuous disturbances, where there are outputs of thermal springs, with water temperatures from 40° to 75°C. This information allows us to identify the most stable and subject to various effects of geosystems.
