The range of rare and protected plants of the Samara and Orenburg regions in the Buzuluk pine forest

The spectrum of protected plant species of the Samara and Orenburg regions growing on the territory of Buzuluksky pine forest is given. It has been established that these species play an important role in the phytodiversity of regions. A greater percentage of Buzuluk pine forest species among the protected areas fall into the latitudinal groups of the forest zone: boreal, boreal-nemoral, boreal-nemoral-forest-steppe, and nemoral. The growth of a number of rare species in the forest, indicated in literary sources, needs to be confirmed. Among them: Cypripedium macranthon Sw., Goodyera repens (L.) R. Br., Lycopodium clavatum L. and Lycopodium annotinum L. Species whose habitats are found only in Buzuluk pine forest are recommended for inclusion in the regional Red Data Books. Recommended for listing in the Red Data Book for the Orenburg region: Calla palustris L., Hammarbya paludosa (L.) O. Kuntze, Eriophorum gracile W.D.J. Koch, Carex arnellii Christ. and others.
