Palestine lies in one of the most geographically and ecologically diverse regions of the Eastern Mediterranean and Western Asia, with exceptionally rich vegetation. Its location at the crossroads of three continents, combined with marked variations in topography, climate, geology, and soil characteristics, has created a complex mosaic of habitats supporting plant species with diverse biogeographical affinities [ 1]. Southern Palestine, particularly the Hebron Governorate, serves as a crucial ecological transition zone separating Mediterranean environments from more arid ones; the area encompasses mountains, highlands, valleys, plains, and agricultural landscapes, resulting in significant diversity in environmental conditions and vegetation patterns. Its geographical location further enhances its ecological significance, as the Dead Sea borders it to the east; the Sinai and Negev deserts and the Red Sea to the south; and the Palestinian coastal plain, the Mediterranean Sea, and the north to the west [ 1,2,3].

Environmental diversity in southern Palestine has given rise to varied vegetation, comprising elements from the Mediterranean, Irano-Turanian, and Saharo-Arabian phytogeographical regions, among others. Palestine boasts over 2,780 plant species spanning approximately 872 genera and 144 families including numerous endemic or regionally restricted varieties [ 4,5,6,7,8,9,10,11,12,13,14]. This botanical richness underscores the importance of studying not only species diversity but also the organization, composition, and ecological relationships of plant communities.

Phytosociology provides a crucial framework for understanding vegetation structure and the relationships between plant species within specific habitats. By identifying and classifying plant communities based on their floristic composition and species abundance, studies in this field yield valuable insights into vegetation dynamics, habitat differentiation, environmental gradients, and plant-environment interactions. Such information is particularly significant in areas where natural vegetation is increasingly impacted by factors such as agricultural expansion, grazing, urbanization, habitat fragmentation, and other forms of human-induced disturbance. Consequently, providing detailed data on plant communities can serve as a fundamental ecological reference for assessing biodiversity, planning conservation programs, and sustainably managing natural vegetation [ 1,3]. Several studies have contributed to the understanding of plant diversity and plant communities in southern Palestine and the Hebron Governorate. Research conducted in areas such as Idhna, Beit Jibrin, Al-Dawayima, Wadi Al-Quff, and other parts of the Hebron region has documented significant plant diversity and revealed distinct plant communities associated with variations in topography, climate, soil, and land-use patterns [ 15,16,17,18,19]. These studies provide an important regional framework for interpreting vegetation patterns in the town of Surif, while also demonstrating that relatively small geographical areas within the Hebron Governorate can harbor markedly different botanical and phytosociological characteristics.

However, numerous studies have been conducted in the Mediterranean region regarding plant vascular and phytosociology [ 18,20,21,22,23,24,25,26,27]. Surif, located in the northwestern part of the Hebron Governorate, is an ideal site for detailed vegetation research due to its diverse topography and varied environmental conditions. Situated at an elevation of approximately 600 meters above sea level, the area encompasses mountainous terrain, woodlands, open lands, pastures, and agricultural habitats. Its temperate Mediterranean climate is characterized by hot, dry summers and cold, rainy winters. The average annual temperature is approximately 18°C, while annual precipitation averages around 560 mm; most rainfall occurs between October and April, with the highest levels typically recorded in January and February [ 28,29]. Together, these factors climatic variability, topographical differences, diverse soil characteristics, and land-use patterns create favorable conditions for the emergence and development of diverse plant communities.

Despite these studies, the vegetation in southern Palestine still lacks sufficient documentation at the local level. Variations in elevation, slope, soil characteristics, moisture availability, land use, and climatic conditions can lead to significant differences in plant community composition over relatively short geographical distances. Consequently, findings from specific sites cannot necessarily be generalized to other areas within the Hebron region; hence, there is a need for detailed local-level studies to identify plant communities, characterize their floristic composition, and elucidate their relationships with environmental conditions.

Accordingly, the present study aims to investigate the phytosociological characteristics of plant communities in the Surif area.

Surif is a Palestinian town located in the northwestern part of the Hebron Governorate, approximately 20 km northwest of the city of Hebron and 32 km south of Jerusalem. Surif has held a strategic location since the Roman era, situated on a mountain ridge rising about 600 meters above sea level. The area was first inhabited during the Roman period and saw the minting of Roman coins, highlighting its historical economic importance [ 30]. The town’s total land area is approximately 31,600 dunums, comprising 13,500 dunums of agricultural land, 400 dunums of woodland, and 9,700 dunums of open land and pasture [ 28]. Its geographical coordinates are 31.6495695° N and 35.0734668° E [ 31]. Surif is bordered to the north by the village of Al-Jaba' (Bethlehem Governorate); to the south by the villages of Kharas and Halhul; to the east by the town of Beit Ummar; and to the west by the villages of Beit Nattif and Beit Shemesh [ 30], as shown in Figures 1 and 2.

Approximately 270 plant samples were selected from the study area, and data were collected on 266 woody plant species found in the forests, hills, and mountains surrounding the town of Surif. The sampling and study sites included the villages of Al-Deir and Jabla; Khirbet Jamrin (home to the shrine of the Companion Abu Ubaidah Amir ibn al-Jarrah and numerous historical houses estimated to be over 350 years old); Khirbet Mushrif; Khirbet Deir Musa; Khallat Ali Ghunaim; Khirbet Abu Shuk; Khirbet 'Alin; Karabin; and other neighboring areas, as illustrated inFigure 3.

In addition, several shrub-covered areas were selected for biological sampling, including plant species representing both traditional and thermophilous vegetation types (Table 1). Vegetation data were collected using the Braun-Blanquet method [ 32], and cover-abundance values were converted according to the scale proposed by Van der Maarel (1979) [ 33]. The study area was divided into three plots (A–C), as shown inTable 1.

To convert the Braun-Blanquet phytosociological cover-abundance values to the Van der Maarel ordinal scale, a 266 × 3 data matrix was constructed. The conversion was performed as follows: Braun-Blanquet values (+, 1, 2, 3, 4, and 5) were converted to Van der Maarel values (2, 3, 5, 5, 6, and 7), respectively. The Braun-Blanquet cover-abundance categories are defined as follows:

5: Species covering more than three-quarters (>75%) of the sample area.

4: Species covering between one-half and three-quarters (50–75%) of the sample area.

3: Species covering between one-quarter and one-half (25–50%) of the sample area.

2: Species covering at least 5% of the sample area.

1: Species abundant in number but with low cover value.

+: Species with very low abundance and minimal cover.

In addition to applying the International Code of Phytosociological Nomenclature to characterize newly defined syntaxa, Euclidean distance measures, cluster analysis, and Detrended Correspondence Analysis (DCA) were employed to examine patterns in plant community composition and address potential gaps in the overall vegetation analysis [ 34,35,36,37,38]. Statistical analyses were performed using XLSTAT integrated with Microsoft Excel.

Furthermore, the results of plant species identification and taxonomic verification were cross-referenced with data from several internationally recognized botanical databases and online resources, including JSTOR Global Plants, the Kew World Checklist of Selected Plant Families (WCSP), Plants of the World Online (POWO), World Flora Online (WFO), The Plant List (TPL), Lebanon Flora, and Flora of Israel Online.

The study of vegetation in the Hebron region encompassed plant species found in Palestine, Syria, Lebanon, Jordan, the Negev Desert, the Sinai Desert, and the Mediterranean coastal region [ 15,16,17,1839,40,41]. Various approaches were employed to analyze the vegetation, drawing upon the works of Scientifics botanicals [ 32,33,36,37,3842,43,44,45,46].

The data were organized into an Excel spreadsheet comprising 266 rows (representing plant species) and 3 columns (representing vegetation survey samples or "relevés") to calculate similarity and distance metrics using a correlation-based approach. Based on this dataset, a Euclidean distance matrix was generated and used as input for Detrended Correspondence Analysis (DCA). Following the construction of correlation and covariance matrices, ordination analysis via DCA was performed to analyze patterns in plant community composition; statistical software facilitated this process by providing a clear classification and ordering of the plant communities.

The analyses identified a single plant association, designated as "Association 1" (ASL1). This association comprises forest vegetation samples from groups A, B, and C, which were grouped together based on the results of cluster analysis and Detrended Correspondence Analysis (DCA).

The majority of the listed species in the inventories (A, B, and C) belonged to Pinus halepensis (L.)

(Rhamnus lycioides L.), Pistacia palaestina Boiss., Pistacia atlantica Desf., Crataegus monogyna Jacq., Rhamnus disperma Ehrenb. ex Boiss., Quercus species, and numerous herbaceous plant species. Additionally, a rich herbaceous layer was recorded, comprising species belonging to the Asteraceae, Lamiaceae, Fabaceae, Brassicaceae, Boraginaceae, and Poaceae families, alongside other taxonomic groups characteristic of the Eastern Mediterranean vegetation.

The plant communities were distributed across Mediterranean bioclimatic belts (meso-Mediterranean and thermo-Mediterranean) under bioclimatic conditions ranging from dry to sub-humid and humid. The vegetation was characterized by Mediterranean forest formations, shrublands, and remnant "maquis" formations, growing on limestone-derived soils, including brown Rendzina and Terra Rossa soils, with pH values approaching neutrality [ 3,25].

This plant community (association) occurred at a mean elevation of approximately 586 meters above sea level. Vegetation height ranged from 5 to 20 meters, with an average of about 10 meters. The sites were situated on slopes ranging from 5% to 30%, and the average vegetation cover density was approximately 75%. Based on floristic composition, physiognomy, ecological characteristics, and the results of phytosociological analyses, the vegetation was classified within the Pino halepensis-Cupressetum sempervirentis association. This association belongs to the Eastern Mediterranean region of Southwest Asia and is characteristic of the inframediterranean, thermomediterranean, and mesomediterranean bioclimatic belts (Figures 4-6;Table 2, ASL1, Lists A-C, Typus Group 1). Accordingly, the newly proposed association has been named Pino halepensis-Cupressetum sempervirentis.

N: native, E: endemic, ASL: Association, and ASL1: association 1.

Furthermore, a total of 266 plant species were identified within this plant community. Phanerophytes predominated, accounting for 36.09% of the total; this category included 66 tree species (24.81%), 14 phanerophytic shrub species (5.26%), 3 geophytic phanerophyte species, 3 phanerophytic climber species, 2 shrubby phanerophytic climber species (0.74%), and 2 dwarf phanerophytic shrub species (0.74%). Shrubs constituted 23 species (8.64%).

The Chamaephyte category comprised 75 species (28.19%), including 17 species of chamaephytic shrubs or sub-shrubs (6.39%). Hemicryptophytes were represented by 64 species (24.06%), including two geophytic hemicryptophyte species (0.74%), while Geophytes accounted for 6 species (2.25%), comprising five geophyte species and one geophytic climber species (0.37%). Finally, Helophytes were represented by a single species (0.37%).Figure 6 illustrates the distribution of these life-form categories.

A total of more than 58 plant families were recorded within this plant assemblage. The families with the highest species richness were: Lamiaceae (35 species, 13.15%), Asteraceae (20 species, 7.51%), Fabaceae (19 species, 7.14%), Rosaceae (15 species, 5.63%), Amaranthaceae (13 species, 4.88%), Boraginaceae (12 species, 4.51%), Solanaceae (12 species, 4.51%), Apiaceae (11 species, 4.13%), Anacardiaceae (9 species, 3.38%), and Rhamnaceae (8 species, 3%), among others. The percentages for the remaining families are shown inFigure 7.

Among the approximately 600 plant species recorded in the Surif area, 266 were woody species. Of these woody varieties, 13 species (4.88%) were endemic, including four sub-endemic species. Herbaceous species were excluded from this study because the research focused specifically on woody plants and shrubs.

Analysis of the Pino halepensis–Cupressetum sempervirentis association revealed strong floristic similarities with a comparable plant community previously described from the western Hebron region, particularly the Beit Jibrin area [ 18]. The principal species shared between the two communities include Pinus halepensis, Pinus pinea, Pinus brutia, Cupressus sempervirens, Cupressus arizonica, Juniperus deltoids, and among other characteristic Mediterranean species.

The study area supports several species of Pinus, including P. halepensis, P. pinea, and P. brutia, together with Cupressus sempervirens L., Juniperus deltoides, and Juniperus turbinata. These species are characteristic of dry, subhumid, and humid Mediterranean bioclimatic zones and are associated with the order Pinetalia halepensis Biondi et al. (2014) [ 47] and the class Junipero phoeniceae–Pinetea acutisquamae A.V. Pérez & Cabezudo (1988), as revised by Rivas-Martínez et al. [ 43]. From a syntaxonomic perspective, this plant community is associated with the classes Quercetea calliprini or (Quercetea palaestini) and Quercetea ilicis Br.-Bl. (e.g., A. & O. Bolòs, 1958) [ 36]. It belongs to the order Pinetalia halepensis [ 47] and falls within the Pino halepensis-Cupression sempervirentis alliance [ 18].

The syntaxonomic interpretation of these associations is presented as follows:

Maquis and forest vegetation:

The Surif area, home to more than 266 species of plants and forest shrubs examined in this study is distinguished by a unique pattern of forest vegetation and biodiversity compared to other Palestinian regions. Situated at a favorable elevation above sea level, the area encompasses steppe landscapes, oak forests, shrublands, and a variety of other plant species. It is characterized by arid climatic conditions, with thermal properties spanning the Inframediterranean, Thermomediterranean, and Mesomediterranean zones, and an annual rainfall ranging from 350 to 600 mm.

This study provides a comprehensive characterization of the phytosociological attributes of the woody vegetation in the Surif area, located in the north-western part of the Hebron Governorate, Palestine. The results reveal a distinct Mediterranean forest plant community dominated by Pinus halepensis L. and Cupressus sempervirens L., accompanied by a diverse array of woody and herbaceous species. The identification of this plant community classified as Pino halepensis-Cupressetum sempervirentis highlights the ecological significance of the Surif area as a representative site for Mediterranean vegetation in southern Palestine.

The floristic composition of this plant community reflects Palestine’s transitional biogeographical location among four phytogeographical regions: Mediterranean, Irano-Turanian, Saharo-Arabian, and Sudanian. This unique geographical position has long been considered a key factor contributing to the remarkable plant diversity found in Palestine [ 4,5,13,18,19]. The coexistence of Mediterranean species such as Pinus halepensis M., Cupressus sempervirens L., Pistacia lentiscus L., Quercus calliprinos W., and Arbutus andrachne L. with species characteristic of the more arid Saharo-Arabian environments such as Retama raetam L., Ziziphus spina-christi L., and Haloxylon salicornicum highlights the distinctive nature of the study area and its high level of ecological heterogeneity.

The dominance of phanerophyte trees (36.09%) within the life-form spectrum indicates the arboreal or forest-like character of this plant community. According to Raunkiaer’s life-form theory, phanerophytes typically predominate in regions characterized by relatively stable climatic conditions and sufficient moisture to support the growth of perennial woody vegetation [ 48]. Furthermore, the high proportions of chamaeophytes (28.19%) and hemicryptophytes (24.06%) reflect adaptation to Mediterranean climatic conditions, particularly seasonal drought and grazing pressure. Similar life-form patterns have been recorded in other ecosystems within the Mediterranean region of Palestine and neighboring countries [ 15,16,17,18,19].

The dominance of plant families such as Lamiaceae, Asteraceae, Fabaceae, Rosaceae, Boraginaceae, and Amaranthaceae aligns with patterns documented across the Eastern Mediterranean basin. These families are key contributors to Mediterranean biodiversity, owing to their ecological resilience, drought tolerance, and adaptive strategies for survival under fluctuating environmental conditions [ 13,49]. The high species diversity observed within the Lamiaceae family in this study is particularly noteworthy, as species from this family constitute a major and distinctive component of the shrubland vegetation and "maquis" communities across the Mediterranean region.

Furthermore, the presence of approximately 13 endemic and sub-endemic woody species underscores the biological value of the Surif area for biodiversity conservation; endemic species are a vital component of Mediterranean biodiversity and often serve as indicators of long-term ecological stability and historical biogeographical processes [ 49]. The presence of endemic plant taxa within the study area supports earlier findings indicating that Palestine serves as a significant center of plant diversity and endemism in the Eastern Mediterranean region [ 3,5,6,7,8,912,13,50,51].

Phytosociological analyses including cluster analysis and Detrended Correspondence Analysis (DCA) identified a single major plant association encompassing the survey sites (A-C). This result indicates a relatively homogeneous vegetation structure across the studied sites, despite local environmental variation. The clustering of vegetation survey samples (relevés) further suggests that dominant environmental factors, including climate, geology, soil characteristics, and land-use history, exert similar influences throughout the study area. Similar vegetation patterns have been documented in neighboring areas within the Hebron Governorate, such as Wadi Al-Quff, Idhna, Beit Jibrin, and Al-Dawayima [ 17,18,19]. The environmental characteristics of this plant association closely align with those described for Mediterranean pine and cypress forests across the Levant. The dominance of Aleppo pine (Pinus halepensis M.) and evergreen cypress (Cupressus sempervirens L.) reflects an adaptation to dry summer conditions, moderate annual rainfall, and calcareous soils. These species are known for their high tolerance to seasonal drought, high temperatures, and relatively poor soils, enabling them to survive and thrive under Mediterranean climatic conditions [ 51,52]. Furthermore, the presence of associated species such as Pistacia palaestina B., Pistacia lentiscus L., Quercus calliprinos W., and Crataegus Aronia L. reinforces the classification of this vegetation within the ecological complex of Mediterranean forests and "maquis" shrublands.

A comparison with the vegetation described in the Beit Jibrin area [ 18] revealed strong floristic similarities, particularly regarding the dominance of species such as Aleppo pine (Pinus halepensis M.), Mediterranean cypress (Cupressus sempervirens L.), and Juniperus deltoides, alongside other woody Mediterranean species. These similarities suggest that the Pino halepensis-Cupressetum sempervirentis association may represent a broader vegetation unit distributed across several areas of the Hebron Governorate. These findings support the syntaxonomic placement of this association within the Pinetalia halepensis order and underscore the importance of Mediterranean pine forests as a key vegetation type in southern Palestine.

From a conservation perspective, however, the study area serves as a vital refuge for native woody Mediterranean vegetation; increasing urbanization, agricultural intensification, overgrazing, frequent fires, and climate change pose significant threats to Mediterranean ecosystems throughout the Levant [ 49,53]. Furthermore, the relatively high species diversity and the presence of endemic taxa recorded in the Surif area highlight the need for long-term conservation and sustainable management strategies aimed at protecting these valuable plant communities. Overall, the results confirm that the Surif area harbours a distinctive Mediterranean forest association characterized by high plant diversity, significant ecological stability, and notable phytogeographical importance. The proposed association (Pino halepensis-Cupressetum sempervirentis) contributes to enhancing the understanding of plant diversity in Palestine and provides a vital foundation for future studies in phytosociology, ecology, and conservation efforts within the Eastern Mediterranean region.

Overall, the study demonstrates that the Surif area harbors Mediterranean forests and woodlands of high botanical and ecological value, characterized primarily by a community of Aleppo pine and evergreen cypress. The documentation of 266 plant species including 13 that are endemic or have a restricted regional distribution highlights significant botanical richness and underscores the area's critical importance for conservation. This plant assemblage reflects the interplay of Mediterranean climate, calcareous soil, topography, moisture availability, and historical land use; furthermore, its floristic resemblance to plant communities in Beit Jibrin suggests a broader botanical diversity across the Hebron region. These findings provide a vital foundation for vegetation classification, biodiversity assessment, and conservation planning in southern Palestine. To maintain the ecological integrity of the Surif area, the study recommends protecting forest patches, preserving habitat connectivity, practicing sustainable grazing, preventing unnecessary vegetation removal, and monitoring endemic species. Future research should expand the scope of surveys and incorporate quantitative measurements of soil characteristics, elevation, slope, aspect, precipitation, grazing intensity, disturbances, and land-use history to better understand the relationships between plant communities and environmental gradients. Ongoing botanical surveys and long-term monitoring will be essential for preserving the native Mediterranean vegetation and biological heritage of Surif and the Hebron governorate at large. Overall, Surif’s study underscores the significant botanical and ecological importance of Mediterranean forest vegetation in the Hebron Governorate.
