Introduction. There are 4500 vascular plants belonging to 125 families and 920 genera in the territory of Azerbaijan [Flora of Azerbaijan, 1950-1961]. According to the general number of species, the vegetation of Azerbaijan is quite rich compared to other republics of the Caucasus. The plant species seen in our country cover 66% of all plant species seen in the Caucasus [Grosshaym, 1936, 1948].
One of the reasons why our country’s vegetation and flora is rich is that it has different ecological environments and habitat diversity. One of these ecological environments is water-swamp areas.
Its depth is less than 6 meters, some common property has sweet, flat and brackish water, lakes, swamps, stagnant stocks of streams, floodplains, sea shores, gulfs, rivers transform into watery ecosystems.
There are 450 lakes in Azerbaijan with a total surface area of 395 km2. These are divided into 7 types as: glacial lakes, flooded lakes, weir sourced lakes, lagoon sourced lakes, karst sourced lakes, landslide sourced lakes and relict sourced lakes [Mammadov, 2011].
Settled in different regions of Azerbaijan; Sarisu (65 kv.km), Agzibirchala (13.8), Akgol (56.2), Candargol (10.6), Buyuk Alagol (5.1), Gokgol (0.79), Hajigabul (8.4) , Buyuk-Shor (16.2), Ashık Kara (1.76), and Karachug (0.45 kv.km) lakes are among the most important areas where water-swamp vegetation spreads [Sultanov, 2011].
The longest river in Azerbaijan is the Kur River, which is 1,364 km long and empties into the Caspian Sea. Aras river is 1.072 km long. The largest natural lake is Sarısu Lake with 67.0 km², and the largest artificial lake is Mingachevir Dam Lake with 605.0 km².
There are many plants that love the aquatic environment and spread around lakes and their surroundings, swamps and stagnant waters, channels and their surroundings, streams, lakes, ponds, artificial dam lakes, which form an important part of Azerbaijan’s land. These are plants that love aquatic and swampy environments and form associations in these environments. This type of plants can be found in all regions of Azerbaijan, in plains and mountainous lands. The water-swamp plant associations are among the relict plant associations and were not affected by the icing cycle and caused the formation of aquatic ecocenoses [Grossheym, 1940]. Water-swamp plants spread widely on the edges of lakes, marshes, reservoirs and canals due to their long evolutionary development time due to their adaptations.
Water-swamp ecosystems are widespread all over the world [Kats, 1961; Aliyev, 1969; Grandstein & Smittenberg, 1977; Katanskaya, 1981; Seçmen & Leblebici, 1984; Bechet & Altan, 1994; Chakan & Temiz, 1993; Chivelek & Chetin, 1993; Golub and Losev et.al., 1991].
Water-swamp vegetation has been explored in many parts of the world. Wetlands in Turkey [Behchet, 1994a, b; Seçen and Leblebiçi 1996; Chakan et al. 2003; Karaomeroglu, 2007], salty wetlands [Aydogdu et al., 2002; Hamzaoglu and Aksoy 2009], flooded areas [Kutbay et al. 1998; Özen, 2010; Kavğacı, 2010] and dune fields [Kılınç and Özkanca 1991; Kılınç and Karaer 1995; Karaer et al., 1997; Çakan et al., 2003; Karagmeroğlu, 2007] some phytosociological studies have been carried out.
[Sechmen and Leblebici 1996] recorded that there are 23 plant associations in the wetlands of Turkey, 31 in coastal meadows, 7 in wet meadows, 1 in wet tree assemblages, and 21 plant associations in salty associations.
[Richard Hırıvnak 2002a., 2002b] gave the vegetation classification of Potametea, Lemnetea and Charetea classes in the region in his studies on the distribution and classification of aquatic plant communities of Slovakia and Bulgaria and examined the phytosociological properties of plant associations belonging to these classes.
İnvestigated the floristic composition of aquatic macrophytes of teas in Bulgaria and in this study divided the aquatic flora of the region into three groups as hydrophytes, helophytes and amphiphytes. [Yucel, 2010] investigated the heavy metal biomonitor feature of Myriophyllum spicatum, which is distributed along the Porsuk River in Turkey [Gecheva et al. et al 2013].
Some of these associations are also found in the water-swamp plant associations of the high mountainous regions of Azerbaijan [Ocakverdi et al. 2009].
Examined the plant associations of the forest vegetation around Taiwan’s Yuanyang Lake and showed that the water-swamp type forest associations are located at an altitude of 1650-2432 m above sea level [Chang-Hung Chou et al., 2000].
[Korkmaz et al. 2012] In a study he carried out in the Golardi Wildlife Protection Area within the borders of Samsun Province in Turkey; It has psammophyte, hygrophyte and forest type vegetation and made a syntaxonomic evaluation of these types. Among the vegetation types determined in this study, it is seen that the degree of similarity among the plant associations found in the coastal areas of the Caspian Sea of Azerbaijan is high [Atamov, 2007].
Water-swamp vegetation in the Azerbaijani land is common in many botanists [Grossheym, 1936, 1948; Prilipko, 1970; Aliyev, 1969; Babayev, 1974; Efendiyeva, 1998; Hajiyev, 1970; Hajiyev et al, 1991; Atamov, 2008; Talibov, Ibrahimov, 2008; Ibrahimov, 2008; Musayev, et.al., 2010]. However, there is a need to make a classification of the syntaxonomic structure of the vegetation in these ecosystems, which is accepted in the world today. In order to explain the syntaxonomic structure of such areas, new and detailed studies are needed [Mucina, 1997].
In the vegetation of Azerbaijan, these ecosystems are more widespread in regular areas and are also encountered in mountainous regions.
One of the regions where this vegetation type is most common is the Lankaran plain located in the southeast of Azerbaijan. In this region, there are many lakes, ponds, swamps and gulfs in orderly parts [Mammedov, 2011]. The Big and Little Kizilagac Bays, which form a natural water-swamp ecosystem in the region and are on the Ramsar list, are among the most important areas in this sense [Sultanov, 2000].
In this area, which is known as the migration route of many birds, the water-swamp vegetation is. It was explored by [Grossheym, 1936, 1948] and later by Aliyev.
[Aliyev, 1969] In the Lankaran plain where water-swamp vegetation is common in Azerbaijan, [Babayev, 1974] İn the high mountain areas of the Lesser Caucasus, [Efendiyeva, 1989] conducted research on the Absheron peninsula, and [Musayev, 2010] on the Kur-Araz plain for many years.
The general vegetation and water-swamp areas of Nakhchivan have also been investigated for many years by Talibov and Ibrahimov. As a result of the studies carried out by these researchers, we see that there are water-swamp ecosystems in different regions of Nakhchivan, adding many taxa to the flora as new records [Talibov and İbrahimov, 2008].
Mammadov shows that factors such as ecological conditions of the environment, water composition, chemical content, salinity degree, altitude above sea level, and temperature play an important role in the emergence of differences in lakes in curing.
While the mesophyll species that prefer ecologically less humid habitats settle in the area, the hygrophilous species that prefer flooded habitats withdraw from the area and a different floristic and structural structure develops. Because there is a strong correlation between the water table depth, soil water content and wetland types in flooded areas and seaside plains (Meendino et al., 1990).
According to the warth the study area can be diveded as temperate zone (over 1800m.), hot zone (between 700-1500m) and extreme hot zone (between 0-500m.).
Annual rainfall per year at the water-marsh vegetation zones is differs between 300-650(700)mm. Summers are extremely hot while winters are cold. The study area is under continental climate which determine the character of the plant cover.
Kur-Araz plain, Kacheti and Avtaran are at the Caucas provence of Azerbaijan which has a tempature betwwen +2 or +3 Co in winters (climate Azerbaijan, 1968.)
In summers izoterm changes in different direction, it rises from North-west to South-east (pic. 1,2).

The physical-geographical and soil-climatic conditions of the region, vertical belting and many other features also affect the development of vegetation. Desert, semi-desert and water-swamp plants have developed up to 200 meters high in the plains of Azerbaijan. Water-swamp ecosystems are also encountered in the mountainous and high mountain regions of Azerbaijan, along with the regular sections. Especially in the subalpine and alpine belts of the Greater and Lesser Caucasus Mountains, many mountain lakes, streams and streams are encountered.
Water-swamp plant associations are seen in the form of spots against the background of desert and semi-desert type plant groups, but in the coastal areas of many lakes and especially on the Caspian coast, Mil, Mugan and Shirvan plains.
Halophytic desert, semi-desert vegetation spreads in the plains along the rivers of Shirvan, Mugan, Mil, Jeyranchol, Kobustan and Aras. In Kur-Aras, Kobustan, and Ceyranchol, zonal formations (Artemisetum) covered a larger area. Other formations, Salsoletum dendroidesae, (Kur-Aras) and Salsoletum nodulosae (Kobustan, Nakhichevan) units are common.
One of the most characteristic plant associations for these lands is the gallery forests formed by water-loving tree species. In particular, the main types of forests along the Kur and Aras river valleys are Populus, Alnus, Fraxsinus, Salix, Eleagnus, Tamarix etc. species belonging to the genus.
Material and Method. Field studies between 2007-2013 in the lakes and marshes settled in the plain and mountainous regions of Azerbaijan, in the coastal areas, especially the Lankaran plain (Great and Little Alder Agac Bay), Samur-Devechi plain (Devechi Harbour), Candar Lake and the lowland and mountainous areas of Nakhchivan. sections (Batabat lake, Araz deryaçası, Goygol lake in Ordubad land), Kur-Araz plain (Hacıgabul, Sarısu) and Absheron peninsula (Masazır duz lake, Lokbatan and Kanlıgöl).
Plants were collected at different vegetation periods and in all seasons. The identification of the collected plant specimens was made according to the 8-volume “Flora of Azerbaijan”. Identified plant samples are kept in the Herbarium Laboratory of the Botanical Institute of the Azerbaijan National Academy of Sciences. Rare, endemic and threatened species were evaluated according to the Red Book of Azerbaijan. The life forms of plants are given according to the [Raunkier, 1934] system. Phytosociological properties and formation of vegetation tables of plant associations Syntaxonomic nomenclature of associations according to the “smallest area” principle according to the [Braun-Blanquet, 1964] method [Weber et al., 2000] was made according to.
Results. As a result of this research, the water-swamp vegetation of Azerbaijan was investigated according to the Braun-Blanquet(1964) method and the syntaxonomic evaluation result is given below.
- In-water (Hydatophyte) units
They are pure plant plants whose bodies settle on or in water in slow-flowing streams, lakes and sea coasts, in gulfs, in places where the water depth is not more than 6 m.

- Coastal (Hydrophyte) water-swamp troops
They are plant plants found in streams, lakes and swamps, in places where the water depth is not very deep. The lower parts of their trunks settle in the marsh, in the soil that is always or occasionally (seasonally) submerged (Helophyte plants). Since they have a developed root system, it becomes easy for them to form troops.
A large number of associations consisting of various species belonging to this class are encountered. It is not possible to set a definite limit among them. Because most of the taxa that participated in the formation of the union are common, but it seems that they passed on to other unions.Sınıf: Phragmitetea Koch 1926

- Hygrohalophyte plant associations
They are associations of hygrohalophyte plants that grow in salty lakes or sea shores, in watery places and salty marshes. These types of units are mostly distributed in the coastal areas of the Caspian Sea, in terrestrial habitats and in flooded areas in the close vicinity of lakes. Distributing in many salty and sweet flooded areas around the world: Halocnemum strobilaceum, Salicornia europea, Frankenia hirsuta, Halimionea verrucifera, Juncus littoralis, J. maritimum, J. acutus are dominant communities in many regions of Azerbaijan, adjacent to coastal dunes, They can spread to lightly salted areas.Sınıf: Salicorniotea Braun-Blanq. 1931

If the plant associations are evaluated according to the “EUNIS habitat classification” (2004) system, it is seen that there are 101 plant associations belonging to 5 habitat types in our research area.
33 plant associations belonging to in-water associations, 31 coastal marsh associations, 13 wet (moist) grass associations, 8 aquatic forest units and 17 plant associations belonging to hydrohalophytes were encountered. Vegetation tables of each of these unions; It was created by considering parameters such as abundance and degree of overlap, life forms, and randomness class of plant taxa that make up the flora of the bird.
Haciyev and Musayev, together with the plant species found in the Caucasus and other regions, there are 240 unique to Azerbaijan only, but 140 plant species according to the newly published “Azerbaijan’s Red Book” work. Among these plants, there are also plants that spread only in water-swamp ecosystems and are under the threat of extinction. It is important to protect water-swamp type habitats in order to protect them and not be threatened.
A total of 502 taxa distributed in the water-swamp ecosystems of Azerbaijan; There are four types of life forms: tree, bush, semi-shrub and herbaceous body [Musayev, et al., 2013].
Picture 3. Vertical profile of water-marsh plants of the Sea coast near the gulf of Gizilagaj: 1, 3 – Hygrophytes; 2,4-Hydrophytes; 5-6 Hydaphytes. Plants:1. Populus nigra, Tamarix ramosissima, Eleagnus angustifolia; 2. Phragmites communis, Schoenoplectus litoralis 3. Juncus acutus, J. İmflectus; 4. Nymphaea alba, 5. Potamogeton pectinatus, P. nodosus ; Ceratophyllum demersum; 6. Najas marina, N. minor
Most of these plants (92%) are herbaceous, while a few (8.0%) have woody stems. 63% of herbaceous stem plants are perennial and 29.1% are annual. 12 (2.4%) trees (Elaeagnus angustifolia, Salix acmophylla, Populus nigra, P.alba, P. hybrida, Tamarix ramosissima, Alnus glutinosa, Quercus araxsina, Pterocaria pterocarpa etc.) and 27 (5%, 4 of them) shrub and semi-bush stem plants were encountered. They participate as character species in the composition of aquatic forest associations. In the water-swamp ecosystems of Azerbaijan; Cryptophyte 219 (43.6%), therophyte 139 (27.7%), hemicryptophyte 101 (20.1%), phanerophyte 40 (7.8%), kamephyte 3 (0.6%) were found to be all life forms [Musayev et al, 2013].
The fact that cryptophytes, hemicryptophytes and therophytes are richer in water-swamp vegetation seems to be one of the characteristic features of this vegetation. Plants with this type of life form adapt easily to the water-swamp environment, and easily reproduce by vegetative means in the aquatic environment. Some of the aquatic plants with rhizome and perennial herbaceous stems grow easily in salty lakes and marshes, and some in freshwater lakes and marshes. These types of plants seem to be characteristic and distinctive and dominant species in water-swamp plant associations, sometimes forming pure and sometimes mixed associations.
It is noteworthy that plants with rhizomatous, reptilian and grassy stems are common and dominant species in the phytosociological structure of water-swamp vegetation. A total of 412 species, which are morphologically divided into different types but have herbaceous life forms, were encountered, of which 128 were rhizome (49%), 37 grass-forming (7.4%), 33 reptile (6%, 6), 14 of them are bulbous (2.8%) and 4 of them are herbaceous stems (0.8%).
40 woody stem plants were found living in a water-swamp environment. This constitutes 8.0% of the total water-swamp flora (table 1).
Water-swamp plant associations are found everywhere in Azerbaijan, starting from sea level to high mountain areas. It is found in wider areas, especially in the Absheron peninsula, Samur-Deveçi, Kur-Araz plain, Alazan-Eyricay, Mil-Mugan, Ceyranchol, Qobustan plains and in the orderly parts of Nakhchivan. Compared to the mountainous areas, the areas covered by the water-swamp vegetation in the regular areas are wider and poor in terms of plant diversity.
When we evaluate according to habitat diversity: plant diversity in habitats around rivers, streams, streams and water channels (312 taxa) is richer than habitats such as swamp (160), calm slow flowing water (127) and salty lakes and sea coast (114 taxa) (table 2).
Aliyev (1969) in his research on the water-swamp vegetation of Azerbaijan recorded a total of 94 plant associations, with 20 in water and 46 in both water and land (table 3).
It was revealed by Babayev (1974) that in the water-swamp vegetation of the high mountain parts of the Lesser Caucasus within the borders of Azerbaijan, there are a total of 51 plant associations: 20 in water, 31 both in water and on land (table 3).
Efendiyeva (1989) determined that in the water-swamp vegetation of the Absheron peninsula, there are 41 plant associations in total, 11 in water and 30 in both water and land (table 3).
It was determined by Musayev that there are 32 plant associations in the water-swamp vegetation of the Kur-Araz plain, 12 in water and 20 in both water and land (table 3).

Researches and syntaxonomic classifications carried out by us have shown that the water-swamp vegetation of Azerbaijan consists of a total of 101 plant associations, of which 12 classes, 16 orders, 26 wedding rings (table 3).
Our studies on vegetation have been carried out based on the principle of dominance only, without considering the habitats, phytocenological structure of the vegetation, and ecologic conditions.
In the next stage, a more detailed investigation of the great lake and water-swamp ecosystems within the territory of Azerbaijan in the separation shows that new plant associations will emerge together with the new flora records.
- One of the vegetation types in the vegetation of Azerbaijan is the water-swamp vegetation. This vegetation spreads locally from the plain to the high mountain areas in Azerbaijan. They are plant associations that spread especially in the marsh environments of lakes and rivers, watering canals and artificial dam lakes.
- Water-swamp ecosystems are divided into 5 types according to habitat types: 1. In-water associations; 33 total; 2. 31 belonging to the coastal marsh units; 3. Age 13 belonging to the grass units; 4. 8 plant associations belonging to aquatic forest units, 5. 17 plant associations belonging to hydrohalophytes were encountered.
- Belonging to in-water units; Ruppietum maritimae, Lemnetum minoris, Lemnetum gibbae, Lemnetum trisulce, Potametum pectinati, Potametum lucentis, Potametum perfoliati, Potametum pectinato – perfoliati, Potameto Najadetum, Myriophylletum trisulce, Potametum pectinati, albametum pectinato – perfoliati, Potameto Najadetum, Myriophylletum slimetum spicinetum, Nebaphyllehyphaetacetum Polygonetum amphibii, Najadetum marinae, Ceratophylletum submersum, Myriophylletum verticillati; Belonging to the coastal marsh associations: Phragmitetum communis , Typho angusfiliae-Phragmitetum communis , Scirpo-Phragmitetum communis, Typhetum angistifoliae, Typhetum latıfoliae, Potamogetono- Typhetum domingensis, Scipetum lacustriteum-Scipetum latifoliae- , Triglochino-Bolboschoenetum martinis, Sparganietum poluedrum, Butometum umbellati, Caricetum paniculatae, Caricetum vesicariae, Typhetum domingensis, Schoenoplectetum litoralis, Calamagrostisetum epigejosae, Hippurisetum vulugarisae, Caricetum vesicariae, Typhetum domingensis; Belongs to wet (wet) grass associations: Carici-Menyantetum trifoliatae, Paspalietum paspalodesi, Juncetum lampolodesi, Juncetum inflexusi, Cyperetum longusiae, Sparganieto-Menyantetum trifoliatea; Belonging to the water-marsh forest associations: Salixetum albae, Phragmeto-Alnetum barbati, Populetum nigrae, Rubeto- Elagnetum angustifoliae, Verbasco thapsus-Hippophaetum rhamnoidesae, Phragmeto communisae-Tamaricetum grabatumae, Populetum alnetume, Populetumegrapulae; Belonging to the hydrohalophyte plant associations: Halocnetum strobilacei, Haliminetum verruciferae, Carici extensor-Holocnetum strobilacei, Salicornio europeo-Halocnemetum strobilacei, Carici extenco-Salicornietum europaei, Spergulario-Haliminetumitumiolitolitor-Jerrucicetum- maritime, Juncetum maritimum, Juncetum litoralisal, Juncetum acutusae, Juncetum gerrdiae, Junco-Tamarici parviflorae, Tamaricetum ramosissimae Alopecuretum ventricosal associations were defined.
