Our paper presents the new and original data on the diversity of coniferous forests in the understudied territory of the southern part of Yugyd Va national park -Europe's largest protected area. Surveys were carried out in 2015-2017 at four model sites in the catchments of the Schugor and Podcherem Rivers. Plant associations were identified using the dominance approach. For the first time for the territory of Yugyd Va national park, the list of plant associations was compiled for a certain area, containing 17 associations belonging to four coniferous forests formations. Spruce (Picea obova-ta) forests have the highest level of coenotic diversity (nine associations from the true moss-, herb- and sphagnum types of stands). Larch (Larix sibirica) forests contain five associations in two types of stands - true moss and herb. Fir (Abies sibirica) forests are represented by two associations from the true moss- and herb types, and Pinus sibirica forests by one association from the true moss type of stands. Two associations of larch (Larix sibirica) forests were revealed for the first time in Russia (Laricetum bistortosum and Laricetum gymnocarpiosum). The distribution area of four associations has been extended: Laricetum purpurea calamagrostidosum, Piceetum saxatili ruboso-hylocomiosum, Piceetum aconitosum, Piceetum oxalidoso-gymnocarpiosum. The diagnosis and classification of soils based on the genetic profile approach allowed us to reveal seven types and nine subtypes of soils in the coniferous forests.
