The pine mountain forest with bearberry is a rare, relict and endangered phytocoenosis in the Middle Volga (Samara Region; Stavropol District). At present, they are distributed in a limited way and only in the area of the Zhigulevsky State Natural Biosphere Reserve named after I.I. Sprygin. On this territory, geobotanical relevs of plots with bearberry were performed. The ecological-phytocenotic and floristic characteristics of the phytocenosis from the position of Braun-Blanquet are given. Ecotopes are located on slopes of different steepness of the western and north-western exposure. The plant community forms several layers. The species composition is not rich. The dominant species are Pinus cretacea Kalen., Arctostaphyllos uva-ursi (L.) Spreng., Carex pediformis C.A. Mey., Polygonatum odoratum (Mill.) Druce, Rhaponticoides ruthenica (Lam.) M.V. Agab. et Greuter, Asperula tinctoria L. Rare species: Arctostaphilos uva-ursi (L.) Spreng., Astragalus zingeri Korsh., Euphorbia zhiguliensis (Prokh.) Prokh., Gypsophila juzepczukii Ikonn., Helianthemum nummularium Mill., Koeleria sclerophylla P.A. Smirn., Pulsatilla patens Mill., Thymus zheguliensis Klokov et Des.-Shost., that are listed in the Red Book of the Samara Region. In recent years, pine forests with bearberry have suffered greatly from fires and are in the stage of degradation. The uniqueness and relict nature of the bearberry phytocenoses in the Zhiguli Mountains requires their preservation.

Samarskaya Luka

Middle-Volga complex biosphere reserve is a specially-protected natural area in Samara region. The reserve was established in 2006 on the basis of Zhiguli reserve named after I. Sprygina and National Park Samarskaya Luka and became the first integrated biosphere reserve in Russia. The main purpose of the reserve is to ensure the conservation of Zhiguli landscapes and forest-steppe complexes of Middle Volga region, the organization of environmental monitoring and the development of careful environmental management system. The most valuable for research are fragments preserved in the reserve steppe areas, found only in small outlier unplowed areas in the southern and south-western part of Samarskaya Luka, in the Zhiguli and Sengileevskaya mountains. These are the remains of the steppe vegetation that once covered much of the plateau reserve. Although currently they are only small areas they cover all types of steppes in Samara region: meadow (north) steppe, present or feather-fescue (south), as well as special versions of steppe - shrubs, rocky and sandy. The uniqueness of the reserve nature, biodiversity, a large number of rare, endemic and relict species and communities could not but attract the attention of botanists from various periods. We consider the most important works from the point of view of studying the steppe vegetation.

The microtoponymy of the Middle Volga region is of particular interest to the author because of the polyethnic and multilingual environment. It is a region of cohabitation of Slavic, Turkic and Finno-Ugric population groups. The facts of ethnocultural interaction are revealed in substrate microtoponyms, which often have Turkic origins.There are also Finno-Volga substratum elements.Many of them were reinterpreted in Russian language.
