description For the first time, information on the flora of the Siverskyi Donets basin in the vicinity of Balakliya town (Kharkiv region of Ukraine) was summarized based on the comprehensive analysis of published data, herbarium material, and own field examinations. Field surveys were conducted during September 2015 and March-July 2016. The surveyed areas were located mainly in the valleys of the Sіverskyi Donets river and some of its tributaries within the former Balakliуa district. The conspectus of flora comprising 933 taxa of vascular plants (including 798 recorded during field surveys) has been prepared. In particular, 739 taxa of native and 194 taxa of alien plants were recorded. The habitats of 14 species from the Red Book of Ukraine were found. The locations of other protected, uncommon and new for the flora of the region plant species were also identified. Several taxa (i.e., some of the calciphytes like Astragalus albicaulis, Linum czernjajevii, Odontarrhena tortuosa subsp. cretacea, Scutellaria supina, and Silene supina) were found out of their previously known ranges. Newly established locations of some other species (e.g., Ephedra distachya, Onosma simplicissima, and Ornithogalum boucheanum) significantly complement previously known chorological data. Finally, information about new findings of such alien taxa actively expanding new areas as Cornus sanguinea subsp. australis, Fraxinus pennsylvanica, Sedum sexangulare, Ulmus pumila, and Vitis vulpina is provided.It has been established that the flora of the Siverskyi Donets basin in the vicinity of Balakliya town is a rich natural center of phytodiversity being under active adventisation. Forest reclamation plantations play a significant role in spreading the alien plants. Railway and the pine terrace of the Siverskyi Donets also serve the migration corridors for many of such alien plants.

Introduction Balakliya is a town located in the south- eastern part of the Kharkiv region of Ukraine, in the subzone of the Northern Steppe. The complex landscape system of the Siverskyi Donets basin leads to the formation of rich and diverse flora and allows its preservation in https://creativecommons.org/licenses/by/4.0/ https://orcid.org/0000-0003-1146-0873 https://orcid.org/0000-0002-3095-7538 14 Plant Introduction • 89/90 O. Shynder, J. Negrash conditions of significant anthropic pressure. Territorially, the vicinity of Balakliya is located between two national phytodiversity centers, Donetsk-Mzhanskyi and Izyumskyi (Dogadina & Bezrodnova, 2011). There are present all main floristic complexes of the Northern Steppe, including pine, petrophytic (cretaceous outcrops), and halophytic (salt meadows). In the XIX century, this area left out of naturalists’ attention. At the beginning of the XX century, Taliev (1904) inspected the cretaceous outcrops west of the village Milova in the river Milova’s valley and noted the poverty of the species composition of its vegetation. Later, Kotov (1965) briefly described the forest vegetation of the Izium forestry on the left bank of Sіverskyi Donets. Today, part of this complex combining various types of forests, floodplain meadows, and sandy areas belongs to the Landscape Park Izyumska Luka (Onyshchenko et  al., 2016). Lavrenko (1973) inspected the western part of the Andriyivskyi Sukhyi Lyman within the former Balakliya district. Aquatic and coastal- water flora and vegetation of the Siverskyi Donets basin in the vicinity of Balakliya has been studied by several scientists (Chernaya, 1982; Dubyna, 2006; Kazarinova, 2015). There are also some publications about some locations, predominantly of rare species, in this region (Bezrodnova, 2015; Gorelova & Alekhin, 2002; Melnyk & Parubok, 2004; Shynder & Saidakhmedova, 2018; Vinichenko, 2007), including the fundamental work “Flora of the Ukrainian SSR” (Kotov et al., 1936–1965). Please also see the additional list of references in the Appendix. Despite intensive investigations, the flora of the Siverskyi Donets basin within the Balakliya vicinity remained incompletely studied. Chorological data are crucial for protecting the rare plants and their habitats, particularly because, in the former Balakliya district’s territory, there are located five sites of the Emerald Network (2021). Material and methods Field surveys were conducted during September 2015 and March-July 2016. The surveyed areas are located mainly in the valleys of the Sіverskyi Donets river and some of its tributaries within the former Balakliуa district. According to the new scheme of administrative-territorial zoning of Ukraine, our research area covered the communities of Balakliya town and the Donets settlement. Collected specimens (403 species on 579 herbarium sheets) were deposited at the Herbarium of the M.M. Gryshko National Botanical Garden of the NAS of Ukraine (KWHA). The plants’ photos from the studied area were also partly uploaded to the iNaturalist (2021) database. The whole set of discovered taxa was divided into two main fractions – native and alien plants. Alien plants include those that penetrated the research area in the historical epoch (from ancient times to the present day). To clarify the primary distribution ranges and habitats of plants, we used several principal reference works (Prokudin et  al., 1977; Protopopova, 1991; Scholz, 1996; Geltman, 2006; Iljinska et al., 2007; Protopopova et  al., 2009; Zvyagintseva, 2013; Protopopova & Shevera, 2012, 2019). Many alien plants were first cultivated, and after that, they naturalized and spread spontaneously to the wild (escaped plants). Such escaped plants were included in the checklist only in case of confirmed reproduction by seeds outside of the primary cultivation area. The nomenclature of taxa conforms to the Plant of the World Online (2021) and Euro+Med PlantBase (2021) databases. Some locations of rare taxa listed in the Red Book of Ukraine (Didukh, 2009) were already known for the vicinity of Balakliya, so we present them here as confirmed. It should be noted that the names of forests and forestries to which these forests belong do not coincide. For example, forest Kreydyanska Dacha belongs to the Balakliyske forestry, and forest Borysoglibskyi Bir belongs to the Vysokobirske forestry. The text periodically indicates several locations (urochysches) (Figs. 1 & 2): Borshchivka – SE 2.5 km, a large gully (49.471125 °, 36.966361 °); Bayrak – W, 4 km, gully (ravine) Khomyn (49.407044 °, 36.776142 °); Milova – cretaceous outcrops on the right slopes of the valley of the Milova river (49.430986 °, 36.662644 °); Balakliya – the valley of the oxbow Lyakhova, the branch of Siverskyi Donets (49.456931 °, 36.821375 °); Plant Introduction • 89/90 15 Checklist of the flora of the vicinity of Balakliya (Kharkiv region, Ukraine) Figure 1.

JI LK NM PO 18 Plant Introduction • 89/90 O. Shynder, J. Negrash f.r. – data are taken from the field record; RBU – taxon listed in the Red Book of Ukraine (Didukh, 2009); r.s. – species rare for the Kharkiv region according to Gorelova & Alekhin (2002) with a supplement of Bezrodnova (2015). Results and discussion During the field surveys, we have recorded 798 taxa of vascular plants, 14 of which are listed in the Red Book of Ukraine (Didukh, 2009), and 58 are regionally rare. The data from the herbaria of the V.N. Karazin Kharkiv National University (CWU – Kharkiv, Ukraine); M.G.  Kholodny Institute of Botany of the National Academy of Sciences of Ukraine (KW – Kyiv, Ukraine); M.M.  Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (KWHA – Kyiv, Ukraine); and V.L.  Komarov Botanical Institute of the Russian Academy of Sciences (LE – St. Petersburg, Russia) were also taken into consideration and completed by information from the published sources. As a result, we have compiled a checklist comprising 933 taxa of vascular plants, including 739 native and 194 alien taxa (Appendix). Many taxa in the studied area exist on the limit of their natural habitats. At the beginning of the 20th century, Lavrenko (Lavrenko, 1973; Kotov et  al., 1936–1965) discovered many edge locations of boreal plant species that grow in the swamps of the Siverskyi Donets basin and on its sandy terraces in pine forests between Balakliya and Zmiiv. Most calciphytes in the studied area are on the verge of their geographical distribution. Our findings of some of them (e.g., Astragalus albicaulis, Cotinus coggygria, Linum czernjajevii, Pimpinella tragium subsp. titanophila, Scutellaria supina, and Silene supina) expand existing vision about their natural habitats. Among the plants that grow in the steppe habitats along the edge of their geographical distribution in the studied area are Ephedra distachya, Erysimum aureum, Inula salicina subsp. sabuletorum, Onosma simplicissima, and Ornithogalum boucheanum. Among the actual directions of floristic researches is the fixation and monitoring of alien plants, many of which pose a threat to aboriginal biodiversity. Many alien plants in the new habitat are becoming invasive – they reproduce en masse, interfere with the normal functioning of natural ecosystems, and often suppress and displace native plants (Protopopova et  al., 2002, 2009; Geltman, 2006; Lambdon et  al., 2008; Protopopova & Shevera, 2012). In Ukraine, Protopopova and Shevera have long studied the questions of phytoinvasion, and recently published the list of highly invasive plants in the flora of Ukraine (Protopopova & Shevera, 2019). According to these authors, the eastern part of the Steppe zone (where Balakliya is located) is classified as a region with a fairly high saturation of species with high invasive potential – over 40 such taxa reported for this region. Zvyagintseva (2013) studied invasive plants directly in the Kharkiv region. She found that the urban flora of Kharkiv includes 312 alien plant taxa, 14 of which have a high invasive potential and are widespread in both artificial and natural phytocoenoses of the urban area. During our study, we confirmed for the vicinity of Balakliya the presence of almost all highly active invasive plants that were reported (Protopopova & Shevera, 2019) for the eastern part of the Steppe (i.e., Acer negundo, Asclepias syriaca, Centaurea diffusa, Fraxinus pennsylvanica, Impatiens parviflora, Prunus serotina, Solidago canadensis, Ulmus pumila, etc.). Also, we found the locations of new and uncommon alien plants, some of which are in the expansion stage and may become invasive in the future (i.e., Centaurea × varnensis, Cornus sanguinea subsp. australis, Mirabilis nyctaginea, Petrosedum rupestre, Populus × canadensis, Prunus tomentosa, Ptelea trifoliata, Rumex patientia, Sambucus racemosa, Sedum sexangulare, Vitis vulpina, etc.). Below we represent detailed descriptions of the locations of native plants listed in the Red Book of Ukraine (Didukh, 2009) and which are rare or present on the edge of the range of their natural distribution. This list is supported by notes about newly discovered alien plants in the flora of the Balakliya district. The complete list of taxa of the flora of the vicinity of Balakliya, including the citations of taxa authors, is represented in the Appendix. Although the generalized list of taxa looks large, it is probably still not complete since we have not been able to cover all ecological groups of plants in the vicinity of Balakliya Plant Introduction • 89/90 19 Checklist of the flora of the vicinity of Balakliya (Kharkiv region, Ukraine) during our field investigations, which lasted less than a full year. The taxonomic diversity of many plant groups (e.g., Carex, Centaurea, Galium, Polygonum, Pilosella, Rosa, and Veronica) has been studied only partly. Nevertheless, we hope that our study will contribute to the knowledge about the biodiversity of the Kharkiv region of Ukraine. Native plants Polypodiopsida Salvinia natans (RBU) – In Balakliya, along the lower reaches of the rivers Voloska Balakliyka (KWHA) and Serednya Balakliyka, occasionally (f.r.), and also on the oxbow Lyakhova (Fig. 2). Several more locations were recorded in the south and south-eastern vicinity of Andriyivka – on Siverskyi Donets and its oxbows (f.r.). Gnetopsida Ephedra distachya (r.s.) – south-eastern vicinity of Borshchivka, a large gully in 2.5 km distance, on the slope of the southern exposure with a loess outcrop (KWHA). The population is represented by two adjacent plots, each of which has an area of approximately 30  m2 (Fig.  2). Coordinates of both sections: 49.47183 °, 36.96881 °, and 49.47148 °, 36.97059 °. In one of them (22.05.2017, together with N.B. Saidakhmedova) at the stage of flowering, we noted only male strobiles on plants, in another – only female strobiles, so these are probably two old vegetative clones. Angiosperms – Monocots Allium decipiens (r.s.) – Western vicinity of Balakliya – sandy steppe, a few plants (KWHA). Bellevalia sarmatica (r.s.) – Vicinity of Bayrak – in the lower part of the Khomyn ravine, above the coast of Siverskyi Donets, several generative individuals (KWHA). Epipactis helleborine (RBU) – Northern vicinity of Protopopivka – in the floodplain oak in the valley of the Siverskyi Donets near the Kreydyana Mountain. In total, 55 generative individuals of the species were recorded in several locations (KWHA). Fritillaria meleagroides (RBU) – Western vicinity of Balakliya, on the sandy steppe, several dozen individuals (KWHA); 0.6  km toward the northwest from the village Bayrak, one individual was found near a small roadside plantation in the Siverskyi Donets floodplain (49.426039 º, 36.834686 º) (KWHA). Gladiolus imbricatus (RBU) – According to literature sources, this is a rather widespread species in the vicinity of Balakliya (Gorelova & Alekhin, 2002). We noted a large population of the species in the floodplain on the left- bank meadow of the Siverskyi Donets, toward the north from the village Bayrak (KWHA). More than 200 generative individuals of the species were recorded on a 100×200  m plot near the Balakliya-Izyum highway (49.426319 °, 36.833014 °). The locus of this population is noted in the east vicinity of Bayrak, on the edge of a deciduous grove, at the top of the slope (49.417950 °, 36.842819 °) (KWHA). Ten generative individuals were growing on the forest’s edge. Also, 14 generative and four virginal individuals grew nearby on fallow. Iris arenaria (RBU, BC) – Western vicinity of Balakliya, sandy steppe, several dozen small clumps of plants (KWHA); south-western vicinity of Balakliya, Kreydyanska Dacha, the quarter Nr 29, and, partly, the western edge of the quarter Nr 30 of the Balakliyske forestry (49.433619 °, 36.818361 °), Landscape Reserve of Local Significance Kreydyanska Dacha (KWHA). In this population, on a total area of about 4  ha, we found near 100 individuals and their groups, mostly with 1–5-flowering shoots. In the most prominent clumps of this population were recorded 69 flowering shoots per 1 m2. Besides RBU, this taxon is also included in the list of rare species of the Landscape Park Izyumska Luka (Onyshchenko et al., 2016). Iris pumila (r.s.) – South-eastern vicinity of Borshchivka, at the top of a large gully, along the edge of the plateau (f.r.). Liparis loeselii (RBU) – It is included in the list of rare species of the Landscape Park Izyumska Luka (Onyshchenko et  al., 2016). Requires confirmation. Muscari neglectum (r.s.) – north-western vicinity of Protopopivka, on the slope of the gully with limestone outcrops (f.r.). Ornithogalum boucheanum (RBU) – South- western vicinity of Borshchivka, in a ravine on the northern slope of a large gully (49.471361 °, 36.970133 °) (KWHA). This young population has the form of a stripe up to 30 m long. About 80 generative and over 100 virginal individuals have been recorded here. This species is 20 Plant Introduction • 89/90 O. Shynder, J. Negrash occasionally cultivated in Balakliya. Toward the west from the city center along the Lyakhova river banks, cultivated plantations of the species occasionally occur near the dwelling. Besides, planted and self-seeding clumps of the plants occur in the forest park (KWHA). Here, a spontaneous population of introduction origin is establishing. Stipa borysthenica (RBU) – Between Balakliya and Andriyivka – Borysoglibskyi Bir, several small loci on the lawn in the quarter Nr 46; on felled areas and along the glades in the quarters Nrs 57 and 65 of the Vysokobirske forestry (KWHA). Stipa capillata (RBU) – The species is quite widespread and is listed for the Balakliya district from the outskirts of Dovgalivka (Bezrodnova, 2015) and other villages. We recorded the following locations: western vicinity of Balakliya – Borysoglibskyi Bir, the quarter Nr 128 of Vysokobirske forestry, a few individuals (KWHA); the eastern part of Balakliya, on the side of the highway, several young clumps of plants (KWHA); south- eastern vicinity of Borshchivka – in a large gully, on the slopes, abundantly (KWHA); north-western vicinity of Borshchivka – near the road on the right slope of the valley of the Voloska Balakliyka river (f.r.); between Milova and Glazunivka – on cretaceous outcrops and steppe areas (KWHA); north-western vicinity of Protopopivka – a large gully, on the tops of the slopes, abundantly (KWHA); Protopopivka, the bank of Siverskyi Donets, on steep slopes, in some places abundantly (f.r.).

Adonis vernalis (RBU) – The species is provided from the vicinity of Milova and Pyatygirske (Melnyk & Parubok, 2004). The phrase “Balakliya district, Kirovo (Herbarium CWP, 1995)” (Melnyk & Parubok, 2004) probably refers to Kvitneve (former name – Kirove village) in the Blyznyukivskyi district of Kharkiv region. We confirmed the occurrence of A. vernalis in the south-western vicinity of Milova – on a small section of the meadow steppe, on the southern slope of the valley of the Milova river (slope 30 ° of north exposure), near the Shebelynskyi chalk quarry (49.433981 °, 36.666033 °) (KWHA). Over 50 generative individuals were found here in the plot of 30 × 30  m. Another locality was found in the north-western part of Protopopivka – on the cretaceous outcrops on the northern slope of a large gully (slope of south-eastern exposure with 5–30 ° inclination) (49.433981 °, 36.666033 °) (KWHA).

Plant Introduction • 89/90 23 Checklist of the flora of the vicinity of Balakliya (Kharkiv region, Ukraine) Ribes rubrum – Balakliya – south-western vicinity, Kreydyanska Dacha, the quarter Nr 8 of the Balakliyske forestry, several self-seeding individuals (KWHA). Ribes uva-crispa – Balakliya – northern part, in the park on the territory of the military base, self-seeding (KWHA); Balakliya – south-western vicinity, Kreydyanska Dacha, the quarter Nr  5 of the Balakliyske forestry (KWHA). Sedum sexangulare – Between Balakliya and Andriyivka – Borysoglibskyi Bir, the quarter Nr  44 of the Vysokobirske forestry, several clumps of plants on a clearing in the pine forest (KWHA); in the same forest, quarter Nr  11, on a sandy road, a small number. The finding of this Central European species in the Balakliya district’s flora indicates that this species migrates to the east along the pine terraces of Siverskyi Donets, expanding its secondary range. Ulmus pumila – Adult 30–50-year- old individuals occur in urban plantations in Balakliya and some plantations in the forestries. Invasive colonies were noted in certain places: Balakliya – center, around the park (KWHA); western vicinity of the Balakliya cement plant – on the edge of Borysoglibskyi Bir, planted trees and in some places self- seeding individuals are abundant (f.r.). Vitis vulpina – Balakliya – western vicinity, Borysoglibskyi Bir, the quarter Nr  128 of the Vysokobirske forestry, a small invasive population on a slope in the pine forest (KWHA); Balakliya – south-western vicinity, Kreydyanska Dacha, the quarter Nr  8 of Balakliyske forestry, adult specimen (KWHA); Balakliya – sporadically on ruderal and clogged areas (f.r.). New locations of aboriginal and alien plant species of the Siverskyi Donets basin in the Balakliya region supplement the existing information about the region’s flora. The overall floristic richness of the Balakliya region is relatively high, although it is conceding to the well-known regional centers of phytodiversity. All the main floristic complexes of the Northern Steppe (nemoral, boreal, steppe, psammophytic, calcephytic, meadow, and swampy) are combined in the Balakliya natural center of biodiversity. The landscape basis of this center is formed by the valley of Siverskyi Donets with a system of tributaries, which is located between the Lyman group of lakes from the northwest and Izyumska Luka from the east. Some of the listed species were found within the Landscape Reserve of Local Significance Kreidyanska Dacha (quarters Nrs 18–21, 24–30, 32–38, and 45–67 of the Balakliyske forestry). In particular, large populations of Jurinea cyanoides and Pulsatilla pratensis and the local population of Iris arenaria are located there, which testifies the phytodiversity value of this reserve. During the study, other valuable areas with rare plants deserving protection, particularly the steppe gully in the vicinity of Borshchivka (Shynder & Saidakhmedova, 2018), were also found. Many alien (mostly escaped) plant species, which are new to the flora of the region and are in the expansiaon process, were recorded. Here, the most invasively active are taxa that are widely used in forest reclamation plantations (i.e., Cornus sanguinea subsp. australis, Fraxinus pensylvanica, Prunus mahaleb, P. serotina, Ptelea trifoliata, Robinia pseudoacacia, and Ulmus pumila). The railway helps distribute the adventive plant species, among which are xenophytes (alien plants that spread spontaneously, e.g., Mirabilis nyctaginea) and escaped plants (primarily those used in the wind-breaking plantations). Many adventitious species were recorded on the pine terraces of Siverskyi Donets, indicating favorable conditions for them. Conclusions In general, 933 taxa of vascular plants were recorded in the flora of the Siverskyi Donets basin within the former Balakliya district of the Kharkiv region of Ukraine, including 798 taxa observed directly during the field surveys. Such high taxonomic diversity indicates that the studied area is a large regional center of floristic diversity, formed by all the Northern Steppe’s major floristic complexes. Moreover, many new rare aboriginal plant taxa locations were discovered, which testifies the high sozological value of some areas. Simultaneously, the presence of new and invasive-active alien plants confirms the active processes of adventisation of the flora of the region. Forest reclamation plantations 24 Plant Introduction • 89/90 O. Shynder, J. Negrash play a significant role in the spread of such alien plants.

Зокрема, серед них виявлено 739 аборигенних і 194 чужорідних таксони. Підтверджено місцезростання 14 видів, занесених до Червоної книги України. Наведено місцезнаходження охоронюваних, малопоширених і нових для флори регіону видів рослин. Кілька видів, насамперед із групи кальцефітів (наприклад, Astragalus albicaulis, Linum czernjajevii, Odontarrhena tortuosa subsp. cretacea, Scutellaria supina та Silene supina), було виявлено за межами їх відомих ареалів. Виявлені місцезростання деяких інших видів (наприклад, Ephedra distachya, Onosma simplicissima та Ornithogalum boucheanum) значно доповнюють існуючі хорологічні дані для регіону. Також, наведено відомості про нові знахідки адвентивних видів (наприклад, Cornus sanguinea subsp. australis, Fraxinus pennsylvanica, Sedum sexangulare, Ulmus pumila та Vitis vulpina), які перебувають на стадії експансії. Загалом, встановлено, що флора басейну Сіверського Дінця в околицях Балаклії є багатим природним центром флористичного різноманіття. Нині у районі дослідження відбуваються активні процеси адвентизації флори та заселення інвазійними видами рослин. Значну роль у розповсюдженні адвентивних рослин відіграють лісомеліоративні насадження, а міграційними коридорами для багатьох таких видів слугують залізниця і борова тераса Сіверського Дінця. Ключові слова: флора, Сіверський Донець, нові локалітети, адвентивні види рослин, рідкісні види рослин

Балаклії (Харківська область, Україна): аборигенні та чужорідні таксони, поширення рідкісних рослин, нові знахідки Shynder, Oleksandr Negrash, Julia For the first time, information on the flora of the Siverskyi Donets basin in the vicinity of Balakliya town (Kharkiv region of Ukraine) was summarized based on the comprehensive analysis of published data, herbarium material, and own field examinations. Field surveys were conducted during September 2015 and March-July 2016. The surveyed areas were located mainly in the valleys of the Sіverskyi Donets river and some of its tributaries within the former Balakliуa district. The conspectus of flora comprising 933 taxa of vascular plants (including 798 recorded during field surveys) has been prepared. In particular, 739 taxa of native and 194 taxa of alien plants were recorded. The habitats of 14 species from the Red Book of Ukraine were found. The locations of other protected, uncommon and new for the flora of the region plant species were also identified. Several taxa (i.e., some of the calciphytes like Astragalus albicaulis, Linum czernjajevii, Odontarrhena tortuosa subsp. cretacea, Scutellaria supina, and Silene supina) were found out of their previously known ranges. Newly established locations of some other species (e.g., Ephedra distachya, Onosma simplicissima, and Ornithogalum boucheanum) significantly complement previously known chorological data. Finally, information about new findings of such alien taxa actively expanding new areas as Cornus sanguinea subsp. australis, Fraxinus pennsylvanica, Sedum sexangulare, Ulmus pumila, and Vitis vulpina is provided.It has been established that the flora of the Siverskyi Donets basin in the vicinity of Balakliya town is a rich natural center of phytodiversity being under active adventisation. Forest reclamation plantations play a significant role in spreading the alien plants. Railway and the pine terrace of the Siverskyi Donets also serve the migration corridors for many of such alien plants. Вперше узагальнено відомості про флору басейну Сіверського Дінця в околицях м. Балаклія (Харківська область) на підставі всебічного аналізу літературних джерел, гербарних зборів та власних польових досліджень. Польові дослідження проводили у вересні 2015 р. та у березні-липні 2016 р.Конспект флори включає 933 таксони судинних рослин зафіксованих у цьому районі, в тому числі 798 таксонів виявлених безпосередньо в ході польових досліджень. Зокрема, серед них виявлено 739 аборигенних і 194 чужорідних таксони. Підтверджено місцезростання 14 видів, занесених до Червоної книги України. Наведено місцезнаходження охоронюваних, малопоширених і нових для флори регіону видів рослин. Кілька видів, насамперед із групи кальцефітів (наприклад, Astragalus albicaulis, Linum czernjajevii, Odontarrhena tortuosa subsp. cretacea, Scutellaria supina та Silene supina), було виявлено за межами їх відомих ареалів. Виявлені місцезростання деяких інших видів (наприклад, Ephedra distachya, Onosma simplicissima та Ornithogalum boucheanum) значно доповнюють існуючі хорологічні дані для регіону. Також, наведено відомості про нові знахідки адвентивних видів (наприклад, Cornus sanguinea subsp. australis, Fraxinus pennsylvanica, Sedum sexangulare, Ulmus pumila та Vitis vulpina), які перебувають на стадії експансії.Загалом, встановлено, що флора басейну Сіверського Дінця в околицях Балаклії є багатим природним центром флористичного різноманіття. Нині у районі дослідження відбуваються активні процеси адвентизації флори та заселення інвазійними видами рослин. Значну роль у розповсюдженні адвентивних рослин відіграють лісомеліоративні насадження, а міграційними коридорами для багатьох таких видів слугують залізниця і борова тераса Сіверського Дінця. M.M.
