  Abstract. The article considers the natural relict forests of Pinus sylvestris L. within the southwestern boundary of the range at the junction of geomorphological areas and floristic areas within Orenburg[1] region. Relict plantings are characterized by high floral diversity and are subdivided on the basis of geobotanical studies into the following associations: grass-mossy pinewoods; lichen pinewoods; oak-linden pinewoods; grass pinewoods of lows and hills – Buzuluksky forest; grass pinewoods of lows; sparse woodlands at rock ridges - Karagai – Pokrovsky forest. Adrianople, Bolotovsky, Aland island forests are represented by sparsely wooded rock ridges with the presence of areas of lows and hills with grass pinewoods. The revealed floristic differentiation between the studied forests is largely associated with isolation and remote location in a limited area in a region with increasing intensity of economic use over the past decades and with the evolutionary processes of the formation of the Pinus sylvestris L. at the junction of two parts of the world of Europe and Asia. They are manifested in the features of the geomorphological structure and convergence of botanical and geographical zones.

Keywords: pine woody plants, relict forests, floristic composition, island phytocenosis, distribution area, Orenburg region
