Some issues relating to rational utilization of valuable game animal resources are considered in the context of the preservation of chorological cores of their populations. An overview of publications on the description of the cores is provided. The cores are assessed in terms of the views of them, developed by this author, as specific territorial entities in which the key elements of animal life cycle are realized. As an illustration, the cartographic model is provided for the anatomic-ecological section of the reproduction core for Kondo-Sos’vinskiy sable, reflecting the features peculiar to a combination and conjugation of the elements of the «inter-core» mosaic which ensure optimal food protectedness conditions for young animals of this species. Some questions as to the location characteristics of the cores are considered in the zonal-regional and altitudinal contexts.Keywords: key stations, contacts of border ecosystems, relationships between areas of different compartments, location, spatial connections.
