TWO ASSOCIATION OF HERBACEOUS PLANT COMMUNITIES IN RIZA RELIC NATIONAL PARK (REPUBLIC OF ABKHAZIA) ^{[№ 8 ' 2016]}
Subalpine meadows communities are widespread in at an altitude of 1600–2400 m above sea level in the Riza relic national park (RRNP), traditionally used as a pasture. Most of them are disturbed in a varying degree, and partially transformed to ruderal communities. So these are highly significant in nature conservation and recreation. Authors set the object to characterize two associations of meadows in RRNP. The dataset is 10 releves executed by authors in the field season of 2013–2015. Participation of species in a vegetation was estimated on Braun-Blanquet scale. For processing of releves the software packages of TURBOVEG and JUICE are used. According to syntaxonomy analysis result communities were attributed to Potentillo ruprechtii-Campanuletum tridentatae association (Hyalopoetalia ponticae Onipchenko 2002, Salicetea herbaceae Br.-Bl. 1948) and Gentiano dshimilensi-Sibbaldietum semiglabrae association (Nardetalia Oberd. ex Preising 1949, Calluno-Ulicetea Br.-Bl. et Tx. ex Klika et Hadač 1944). The first one combine low-herbage alpine meadows of low alpine belt. These are chacterized by significant snow accumulation in winter, short vegetation period and located on south slopes of mountains. The second one combine subalpine meadows communities on poor rocky soils (above 15 % of substratum rockiness). These are located on moderatly steeep north and north-west slopes. There are rare and conservation needed species in floristic composition of association: Traunsteinera sphaerica (Red book of Russian Federation included), Potentilla ruprechtii, Cystopteris fragilis, Coeloglossum viride (Red book of Krasnodar district). Communities have high nature conservation importance because of its small distribution area in RRNP and lack of sufficient protection at the present time.

RELIC PETROPHYTIC STEPPE COMMUNITIES OF SOUTH URALS STATE NATURE RESERVE ^{[№ 7 ' 2016]}
The results of investigations relic petrophytic steppe communities of South Urals state nature reserve are presented in the paper. Communities are the fragments of relic petrophytic-steppe vegetation on the base rocky exposures. They are located on rocky steppes near-river slopes and dry (usually pine) forests on the insolated south or south-eastern slopes of western part of reserve, mainly on the coastal rocks along Big and Small Inzer river. The dataset consists of 17 geobotanical releves made during 2014–2015. According to results of syntaxonomical analysis studied communities are classified as new association of Euro-Siberian steppe class Festuco-Brometea. It is allocated to meadow steppe Festucion valesiacae alliance (Festucetalia valesiacae order) and petrophytic steppe Centaurеnion sibiricae suballiance. Communities are located on the different parts of south slopes with high soil rockiness (45–90 %). Aizopsis hybrida dominates in the herbage. Such shrubs as Spiraea crenata, Cerasus fruticosa, Cotoneaster melanocarpus, Rosa majalis, Caragana frutex play an active role, but do not dominate. The significant part of coenoflora consists of petrophitic steppe species: Centaurea sibirica, Artemisia frigida, Thalictrum foetidum, Vincetoxicum hirundinaria, Allium rubens, which are presented with high constancy and abundance. There are 3 Red Book included species in the coenoflora: Astragalus clerceanus, Stipa pennata, Tulipa biebersteiniana. Such habitat features as south slopes locations in mountain-forest zone and lack of forest and meadow species competition are probably the organization factors of relic petrophytic steppe communities. The lack of grasing and as a result steppe shrubs (Spirаea crenata, Caragana frutex) overgrowing are the limited factors for these.

SYNTAXONOMIC ANALYSIS OF STEPPE COMMUNITIES OF THE SOUTH OF THE BASHKIR CIS-URALS ^{[№ 10 ' 2015]}
Steppes in the territory of the Republic of Bashkortostan Cis-Urals are fragmented and are mostly located on the south slopes in steppe and forest-steppe zones. At the present time these communities are insufficiently studied in the region. The aim of article is to reveal the diversity of the floristic composition of the RB Cis-Urals south part steppes and represent it in Braun-Blanquet system units. The analysis was conducted with using the computer software: Turboveg, Twinspan, Juice. 19 geobotanical releves of plant communities made during the field season of 2013 by authors are the basis of analysis. According to results of syntaxonomic analysis three associations and two community without rank were allocated. They belongs to the meadow steppes order Festucetalia valesiacae and true steppes order Helictotricho-Stipetalia (class Festuco-Brometea). Bunch grasses dry steppes are presented by association Artemisio austriacae — Stipetum lessingianae. petrophytic communities on the limestones are combined in association Salvio nutantis — Stipetum korshinskyi и community Artemisia lerchiana-Krascheninnikovia ceratoides. most mesophytic meadow steppes is classified in association Poo angustifoliae — Stipetum pennatae. Low species richness pastures combined in basal communities Festuca pseudovina [Festucetalia valesiacae] и Stipa capillata [Festucetalia valesiacae].

THE EXPERIENCE OF SEGETAL VEGETATION COMMUNITIES CLUSTER ANALYSIS OF SOUTH URAL ^{[№ 5 ' 2013]}
The cluster analysis of vegetation communities segetal Southern Urals (Bashkortostan), using the program TWINSPAN was carried out. Identified three leading factors differentiating communities — a zone-climatic factor, factor of the time (change of farming) and agrocenotic factor.

ANALYSIS OF ADVENTIVE COMPONENTS STEPPE AND MEADOW COMMUNITIES IN SOUTHERN URALS ^{[№ 5 ' 2013]}
The adventive component coenoflora of orders meadow and steppe vegetation of the Southern Urals (within the Republic of Bashkortostan) are considered. Geographic structure, time and method of introduction, the spectrum of life forms were analyzed. Identify groups of species with different ecological and phytocoenotic range. Calculated degree adventization of different orders of meadows and steppes in the region.
