The <i>Halocnemum strobilaceum</i> type of grassland is located in the Barsakel’mes, Sarykamysh, and Churuk regions of the Karakalpakstan Ustyurt and occupies 76 492 ha. This type of pasture consists of three varieties: <i>Halocnеmum strobilaceum</i>, <i>Halocnеmum strobilaceum–Kalidium capsicum,</i> and <i>Halocnеmum strobilaceum–Haloxylon ammodendron</i> as wet and puff solonchaks with highly mineralized groundwater very close to the surface, as well as to loamy and sandy loamy solonchakous soils. The plant cover is thin and predominated by shrubs and semi-shrubs, its species composition is poor, and the communities are monodominant and are assigned to the <i>Halocnemum</i> pasture variety. This is explained by the high salt content in the soil, which can be tolerated by a limited number of species. The seasonal yield of the forage mass ranges from 90 to 430 kg/ha.

During the restoration of steppe ecosystems on the territory of the Kulikovo field, various methods and approaches have been used over the past 20 years, which has made it possible to form agrosteppes of different ages. However, the diversity of their vegetation has not yet been assessed. The goal of this study was to identify the coenotic diversity of agrosteppes based on the ecological–phytocoenotic approach and to assess the directions of succession development of the selected associations. The authors carried out 96 geobotanical descriptions of the vegetation of agrosteppes, indicating the total projective cover for the grass layer and the projective cover (%) for each species. The ordination of descriptions was performed on the basis of a trendless DCA correspondence analysis using the PC-ORD program. To compare the identified associations, the indicator of species activity was determined. According to the results of the study, five associations of agrosteppe vegetation were identified. At the early stages of development of agrosteppes, communities of the <i>Matricaria inodora</i> + <i>Artemisia absinthium</i> association are formed, which are characterized by the dominance of taproot species. Densely tufted grasses grow in the communities of the <i>Stipa</i> spp<i>.</i> + <i>Festuca valesiaca</i> association. However, the low competitiveness of densely tufted grasses in the climate conditions of the northern forest–steppe contributes to the loss of fescue and its replacement by narrow-leaved bluegrass, which leads to the formation of the <i>Stipa</i> spp<i>.</i> + <i>Poa angustifolia</i> association. Wood reed is actively introduced into the communities of agrosteppes and increases its activity, which leads to the emergence of the <i>Calamagrostis epigejos</i> association. As agrosteppe communities develop, the activity of anthropogenic and some sown steppe species decreases, but an increase in the activity of meadow grasses in the selected associations is noted. This analysis indicates a low degree of preservation of “feather grass” associations and the formation of communities of steppe meadows.</p>","PeriodicalId":44316,"journal":{"name":"Arid Ecosystems","volume":"13 4","pages":"403 - 411"},"PeriodicalIF":0.8,"publicationDate":"2023-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138438337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biochar, nitroammophos, sodium humate, and Baikal EM-1 were added to oil-contaminated soil (5% of the soil mass). To assess the effectiveness of remediation of brown semi-desert soil after 30 days, the residual oil content, the activity of catalase and dehydrogenases, the number of bacteria, the length of the roots, and the germination of radish were studied.

The floristic composition of plant communities is studied on the basis of 17 geobotanical descriptions. The taxonomic analysis of the flora has been performed and the spectrum of the leading families, Poaceae, Asteraceae, Lamiaceae, and Fabaceae (Po-As-La + Fa spectrum), typical for the Central Asian type with a significant effect of the Mediterranean flora has been revealed. The biomorphological analysis shows the predominance of hemicryptophytes (45.4%) and therophytes (33%). The latter are an indicator of arid conditions and anthropogenic impacts on cenoses. Geographical analysis reveals the predominance of species of the boreal (30.4%) and the ancient Mediterranean (27%) types and shows the position of the region at the contact of the boreal and xerophilous vegetation types. It reflects the development of the flora at the boundary between the Euro-Siberian and Iranian–Turanian regions, followed by the penetration of the Western Asian flora, which is typical for the Caucasus. We suppose that the <i>Paliurus</i> communities of Piedmont Dagestan are primary based on the results of floristic studies, on the xerophytic composition of species in the shrub layer, and on the absence or single participation of species of the genus <i>Quercus</i> in the group of <i>Paliureta</i> <i>graminosa</i> associations and the <i>Paliuretum</i> ass.
