This study focuses on the northern region between the municipalities of El Biodh and Mécheria, which is divided into three sites: Site A, Site B, and Site C. The Transformed Soil Adjusted Vegetation Index (TSAVI) was employed to monitor the evolution of vegetation cover and degradation resulting from these projects, and a concept of fuzzy logic was used to build a map for desertification and drought severity using TSAVI, SVI (sandy veil index) and LST (land surface temperature) over five years 1984, 1994, 2000, 2013 and 2023. The results revealed varying degrees of success among these projects, with some achieving their objectives and others experiencing degradation. The contributing factors can be summarized as follows: climate change emerged as a major influencer, with high temperature values and low precipitation rates causing interconnected damages. Overgrazing impacted the pastoral plantation project, which achieved some success despite being degraded. Urban sprawl has affected the green belt project, which has been deteriorated due to trees felling for urbanization. The choice of plant species, namely Pinus halepensis and Eucalyptus camaldulensis, in rehabilitation projects led to no regeneration and subsequent degradation due to their incompatibility with the harsh climatic conditions of the region. This was observed in projects, such as green belt project and mass tree afforestation. In contrast, the sand dune fixation project exhibited significant development over the years, attributed to the use of Tamarix articulata and Retama raetam species, known for their tolerance to the climatic conditions of the study area, and were very useful to stabilize the sand and protect the area.","PeriodicalId":44316,"journal":{"name":"Arid Ecosystems","volume":"15 1","pages":"9 - 25"},"PeriodicalIF":0.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927010","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}

The de Martonne aridity index decreased significantly (by 1.16 per year, on average), which indicated arid warming. Temperatures increased in all seasons, while precipitation shifted from summer and autumn to winter and spring against the background of a general decrease. The structure of the vegetation cover was dominated by grasses, the share of which averaged 62%. The effect of precipitation on the total productivity of the phytomass was the leading one and amounted to 51.3%. The overall decrease in precipitation favored a decrease in the phytomass of the studied plant groups, except for cereals, the productivity of which became greater with an increase in precipitation in winter and spring. These changes resulted in a further increase in the proportion of grasses in the plant cover of steppes on Vodnyi Island and to a decrease in the participation of other families. The revealed climatic trends will contribute to a drop in the productivity of the aboveground phytomass of steppes on Vodnyi Island, of grasses, in particular.","PeriodicalId":44316,"journal":{"name":"Arid Ecosystems","volume":"15 1","pages":"1 - 8"},"PeriodicalIF":0.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927040","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}

Cenoses are poor in species composition and include from 1 to 10 species. The exception is the formation formed by Artemisia santonica, which has 42 species. The communities of the Caroxylon dendroides, Kalidium foliatum, and Anabasis salsa formations are located at the northwestern limit of their range, most of which are located in the vast Iranian–Turanian desert. The cenoses of Halocnemum strobilaceum have a wider range – the Mediterranean (from North Africa to Middle and Central Asia). Communities of Halimione verrucifera, Artemisia santonica, Frankenia hirsuta, and Limonium suffruticosum are distributed from the Black Sea region to the Caspian lowland (Lavrenko, 1980). The communities of the hyperhalophytes under consideration are confined to a certain type of salinity and the range of the position of the groundwater level. In the northern part of the region, the sodium sulfate type of salinity predominates mainly in the first meter of soils, and communities formed by Artemisia santonica, Caroxylon dendroides, and Anabasis salsa are associated with these conditions. In the southern part, chlorine ions dominate in the salt composition of soils, and the cenoses of other formations are associated with these conditions (Goryaev, 2019; Goryaev, Korablev, 2020). The novelty of the work is related to the fact that, based on research data conducted in the period 2017–2024 in the North-Western Caspian lowland, located in the desert zone, the ecological and phytocenotic classification of hyperhalophytic dwarf semishrubs communities was performed for the first time, ordination and cluster analysis was carried out with respect to salinization and soil moisture factors.","PeriodicalId":44316,"journal":{"name":"Arid Ecosystems","volume":"15 2","pages":"200 - 208"},"PeriodicalIF":0.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927076","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}

Such data are not available for the conditions of the Northwestern Caucasus. The goal of this work is to investigate the pattern of change and to calculate the values of reduction numbers of tree heights in the shelterbelts of the region. For this purpose, problems related to measuring tree heights in the inner and outer rows of shelterbelts were solved. The values of reduction numbers were determined using various methods, and models of their change depending on the rank of trees were created. Ten trial plots with 106–141 individuals in each were laid out for the five main species. Reduction numbers were determined using the classical Schiffel method, average values for rank groups, and newly created models. The value of reduction numbers did not depend on the type of tree species (F = 0.011, P = 0.999) or the row of growth in the belt (F = 0.0002, P = 0.995) and changed in parallel in the inner and outer rows (T = 0.058, P = 0.9528). A similar trend was observed when using the method of averaged values for rank groups. The reduction numbers of heights in forest shelterbelts, when compared with the classic ones for massive forest plantations, demonstrated a difference of over 5% in the extreme ranks; with Schiffel’s data, rank 10 at 5.98, rank 100 at 10.4; with Davidov’s data, rank 100 at 10.4%. This indicates the need to clarify the values of reduction numbers for the objects under study. An adequate model (R 2 = 1) was developed, and new values of reduction numbers of heights for trees growing in forest shelterbelts of the Northwestern Caucasus were calculated on its basis.","PeriodicalId":44316,"journal":{"name":"Arid Ecosystems","volume":"15 1","pages":"117 - 122"},"PeriodicalIF":0.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927009","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}

These studies were conducted on different phytocenoses under anthropogenic load. The species is characterized by low–medium plasticity and medium variability of the morphological traits. In undisturbed cenopopulations, high vitality (IVC = 0.87) and a large proportion of pregenerative individuals are observed. Increased anthropogenic impact leads to a decrease in vitality (IVC = 0.62). An ontogenetic structure with the left-sided (CP 1) and centered type (CP 2, 3, 4) is observed. The characteristic ontogenetic spectrum of Trifolium repens is left-sided, with an absolute maximum in one of the pregenerative groups. Cenopopulation 1 coincides with the characteristic type of the species studied; it has no anthropogenic load and a high projective cover (90%), and the density of individuals is 5.3 ind./m2. Cenopopulations 2–4 do not coincide with the characteristic one. Their young fractions die off, and middle-aged individuals accumulate. The reasons for the reduction in the number of individuals are the negative impact of the anthropogenic factor and climate change.","PeriodicalId":44316,"journal":{"name":"Arid Ecosystems","volume":"15 1","pages":"74 - 80"},"PeriodicalIF":0.6,"publicationDate":"2025-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927041","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}
