The results of the field geobotanical investigations conducted in the Zeya Reserve (north of Amur Oblast) in June 2013 are presented in the article. Geobotanical descriptions of different altitude and various genesis forest and shrub communities have been carried out: spruce forests (Picea ajanica), stlanechnik with domination of low pine (Pinus pumila), birch and birch-oak forests with the participation of Betula platyphylla and Betula lanata, as well as birch-oak forest with dominance of Mongolian oak (Querqus mongolicus). The article contains new data on the location of some rare species of mandzhujrsk flora: Mongolian oak and Chinese Magnolia-vine. All chosen and described loci have the low level of disturbance. Described forest and shrub communities are promising for monitoring, conservation and restoration of forest areas on the territory of the reserve. Completed map of loci can be a background for monitoring of biota in changing climatic conditions. That is particularly important for the loci which have been found within protected areas.
