Mountain ecosystems play an important role in ecosystem stability, especially for biodiversity protection and sustainable development and ecological security. This research was conducted with the aim of the investigating the composition and diversity of plants and the process of their changes in the elevation profile of Alvares to Sabalan (2300 to 4811 meters above sea level) with different elevation classes in the southeast slope, to protect gene reserves and management rangelands in this region.

After field investigations and according to the possibility of access to rangeland in the area, nine elevation classes (sites) were determined, three 100-meter transects were established in each site, and 10 one m2 plots were established along each transect with a distance of 10 meters from each other. Plant species were collected from the surface of the plots and then identified in the herbarium. In each plot, the percentage of vegetation cover and the density of species were recorded. The highest elevation that led to the collection of plant samples was Sabalan 4480 meters. Shannon, Simpson, Margalef and Menhinich indices were used to check the diversity and richness of plant species. Using the information related to measuring the percentage of canopy cover and the number of observed species, the indices of diversity, richness and evenness of species were calculated for the selected sites. One-way analysis of variance (ANOVA) was used to investigate the differences between the sites in different elevation classes, and Duncan's test was used to compare the means. Various indices are used to determine species diversity, among which two indices, Simpson and Shannon-Wiener, were used. Species richness was also determined using Margalef and Menhinick indices and analyses related to vegetation ranking including Canonical correspondence analysis (CCA) were performed.

The results showed that the Asteraceae family with 31 species, Astragalus with 10 genera are the most prominent elements of the region's flora. According to the results of this research, 33% of the identified species were related to Iran-Turonian region. The forms of Hemicryptophytes with (54%), Therophytes with (22%) were the most abundant biological forms in the region. The highest amount of diversity, richness and evenness was observed in the elevation class of 2200-3200 meters. The results showed that elevation, precipitation, temperature, soil sand content, slope and phosphorus were effective factors on the distribution of species. The greater compatibility of plants with the environmental conditions of the region has caused hemicryptophytes to form the dominant biological type of the region, the justification for the high presence of Therophytes is also the result of human interference and concentrated livestock grazing, road construction and recreational areas.

In examining the effect of elevation on the composition and diversity of plants, it can be concluded that the elevation affects the composition and diversity of plants, it seems that the condition of the composition and diversity of species in the southeast rangelands of Sabalan, based on the indicators of diversity and evenness, the rangelands have medium diversity conditions and are increasing is low indicating the intensity of destruction in the entire investigated areas, probably the cause of destruction at lower elevation, the impact of livestock grazing, as well as the effects of tourism activities and Alvares ski resort, and the causes of destruction at elevation above 3600 meters, the trampling of plants by mountain climbers and in the result is the loss of plant species. In general, the main reason for the low diversity in high elevation seems to be the decrease in temperature and the harsh conditions for the growth of plants.

To investigate the effect of different stages of seed maturity at the time of harvest, on emergence indices, physiological and functional characteristics of borage, the seeds of maternal plant were used and an experiment was carried out in a randomized complete block design with three replications at the University of Mohaghegh Ardabili. The experimental treatment was the different stages of maturation of the seeds of the maternal plants at the time of harvesting, which were harvested from the maternal plants at three times (23, 32 and 38 days after flowering). The results showed that the effect of maturation stages at the time of seed harvesting from maternal plants on all measured traits (emergence indices, photosynthetic pigments of chlorophyll, secondary metabolites and grain yield components) was significant. The seeds obtained from the second stage of seed harvesting (32 days after flowering), due to the favorable maturation of seeds, with an increase in the percentage and rate of germination, improvement in the growth and rapid establishment of the plants, an increase in the amount of photosynthetic pigments of chlorophyll and the formation of a favorable plant density in the field, compared to the two masses of seeds obtained from the first and third stages of seed harvesting, had the greatest effect on increasing flower yield, grain yield, 1000-seed weight and other components of Grain yield. The highest amount of phenol and flavonoid was observed at the time of planting the seeds with harvest time 38 days after flowering,

To investigate the effect of the maternal plant's growth environment on qualitative characteristics and germination of borage seeds after storage, an experiment was carried out in a randomized complete block design with three replications at the University of Mohaghegh Ardabili. The treatments included seeds resulting from maternal plants sprayed with humic acid (0.5 g L-1), chitosan (1 g L-1), and the combination of humic acid and chitosan (0.5 g L-1 + 1 g L-1), salicylic acid. (4 mM), ascorbic acid (0.85 mM), potassium nitrate (20 mM) and control.The results showed that under non-storage conditions, the seeds that resulted from the maternal plants treated with bio-stimulants and growth regulators exhibited higher seed germination and seedling growth than those from the control plants. In this condition, foliar application of the maternal plants with humic acid+chitosan had the highest effect on the seed germination and seedling growth characteristics by increasing the germination percentage and rate, vigor index, seedlings dry weight and length. Although five years of dry seed storage reduced the seed viability and vigor, foliar application of maternal plants reduced the negative effects of storage on germination and enhanced the seed germination percentage and seedlings length, and dry weight by increasing the seed viability and seed vigor index. In general, among the foliar spraying treatments of the maternal plants, the combined foliar application of humic acid+chitosan, maybe due to the synergistic effects, can be considered the best treatment to improve the borage seed longevity, germination characteristics, and seedling growth.

Choosing the suitable species, sowing method and sowing season are three important factors for the success of rangeland restoration. The present study was conducted to investigate the effects of sowing season and sowing methods on vegetative growth and establishment of Astragalus lilacinus in rangelands of Ardabil province during 2014-2015. Seeds of Astragalus lilacinus collected from its natural habitats and after its viability testing, it sown in a split-plot design based on randomized complete block with three replications. Factor A was sowing season at two levels (autumn and spring) and Factor B, was sowing method at two level (Scatter seeding and row seeding). The seeds were sown under dryland farming conditions. Data collected for establishment rate, canopy cover, plant height, and the flowering stems number over two years. The data were analyzed of variance and the mean comparison was performed using Duncan's method. The results showed that the seedling establishment rate was 28.5% under rainfed conditions. The higher establishment percentage with an average value of 33.6% obtained in the scatter seeding that was significantly higher than row seeding (23.6%). The sowing season by sowing method interaction effect was significant for canopy cover (P<0.05) and the higher value of canopy cover (2398cm2) was obtained in autumn season using scatter seeding method.

Fire is one of the dynamic and effective factors on forest and rangeland ecosystems so that the evaluation and monitoring of its effects has an important role in planning and management of natural ecosystems. To determine the short-term effect of fire on vegetation changes, a burned area and a homogeneous area without fire (control) in Vanon Khalkhal region were selected. Four transects with length of 200 m were established using systematically random method and 10 plots of the 1 m2 were installed on each transect at a distance of 20 m. Vegetation sampling was done for 3 years in 2018, 2019, and 2020. The results showed that there was a significant difference in density, forage production and canopy cover percentage during the studied years. The average plant density in burned area in 2018, 2019 and 2020 years were 25.05, 31.65 and 33.91 N/m2, respectively and in the control area at the same time were 17.74, 18.17 and 22.84 N/m2, respectively. Forbs decreased from 40.1% of canopy in the control area to 23.4% in the burned area, while grasses increased from 28.2% in the control area to 59.4% in the burned area. Therefore, the fire has been effective in increasing grasses and reducing forbs. In general, Bromus tomentellus, Festuca ovina, Agropyron repensis and Agropyrun trichophorum due to their fire resistant and presence in the burned area are recommended for the rehabilitation of burned areas.

To investigate the effects of hydropriming and foliar application of chitosan and humic acid on physiological and yield characteristics of borage, a factorial experiment was carried out based on a randomized complete block design with three replications at Medicinal Plants Research center of Samian Ardabil in 2017. Treatments were seed priming in two levels (non-priming (control) and hydropriming for 48 hours), and foliar application in four levels (control, 0.5 g.L-1humic acid 1 g.L-1 chitosan and combination of humic acid and chitosan). Results showed that hydropriming significantly improved the grain yield (1.23 fold) and yield components of borage plants compared to control; may be through the increasing in the photosynthetic pigments content. Foliar application of humic acid, chitosan and combination of humic acid and chitosan, significantly increased the flower yield in the plants obtained from primed seeds. Although hydropriming increased the 1000-grain weight and grain yield, the foliar application caused a further increase these traits, so that, in the plants from primed seeds, the foliar application of humic acid and utilization of humic acid and chitosan were significantly increased the 1000-grain weight (1.22 fold) and biological yield (1.69fold) compared to control, respectively. These results indicate the synergistic effects of hydropriming and utilization of humic acid on borage growth and yield characteristics under field condition.

Potamogeton communities are specific to the fresh waters of mountainous areas and highlands. The northern and eastern slopes of Sabalan Mountain and the heights of Talesh Mountain (Baghru) from 1800 to 3000 meters above sea level, have numerous small and large wetlands that have provided the background for the emergence of Potamogeton nodosus community. Alvares mountainous lagoon located at an altitude of 3000 meters on the eastern slopes of Sabalan and Neor Wetlands at 2480 m in Talesh Mountain (Baghro), with Potamogeton communities are beautiful landscapes of Iran's nature. Their remoteness and cold and icy nature in autumn and winter to mid-spring, has caused them to remain pristine.The life form of Potamogeton community is floating or aquaticplants. Potamogeton nodosus Poir.in the higher altitudes and Potamogeton pectinatus L. in the middle altitudes, are the predominant species. From the depths to the edge of the lake, along with Potamogeton communities, several species such as Mentha aquatic L., Blysmus compressus Panz. and Polygonum amphibium L. are visible.

Sabalan is the third highest peak in Iran and one of the high mountain ranges of the South Caucasus in Iran. The Sabalan Mountain has three famous peaks, whose great peak is called the Savalan Sultan, located at an altitude of 4811 meters above sea level. The other two peaks are the Heram and Kasra located on the northern and southern sides of the main peak. The Sabalan peak is in the list of natural national treasures of the country with the registration number 12 /19496. This ecosystem is rich in plant and animal species due to its biodiversity, valleys and slopes. The presence of alpine, subalpine, and some endemic species is a feature of the Sabalan ecosystem. High peaks over 4,000 meters above sea level with glaciers has provided the grounds for the formation of meadows, unique landscapes and consequently, good conditions for the range management, beekeeping, tourism and mountaineering. The nomadic community of Elsuvan (Shahsuvan) is the only population in the area exploiting rangelands. Regarding the damages caused in Sabalan due to overgrazing, climate change, exploitation of medicinal plants in natural habitats, development of the road system in these mountains and tourism programs, the necessity of reviewing the environmental management of the area and paying attention to the sustainable exploitation of the Sabalan ecosystem is very important and a matter of necessity and urgency.

Knowing the ecological characteristics of plants and consequently changes in forage production during the season of grazing for grazing management is essential. Therefore, understanding the annual and monthly production of different rangeland types is essential for efficient and effective forage management. Consequently, relationships between forage production and climatic variables should be considered. For this purpose, the annual forage production was measured in the research exclosure of Arshaq Site rangelands in Ardabil province during 2007-2010 by clipping and weighing method. The monthly rainfall in this period was calculated using Mashkin-Shahr synoptic station data and then the amount of cumulative rainfall in winter and spring of each year was calculated. Afterward, the relationship between production and winter and spring rainfall as well as rainfall of different months of winter and spring was studied separately. Statistical analysis was performed using SAS software. According to the results, the average forage production during four years was calculated of which 28.95% belonged to Artemisia fragrans, 26.35% to Kochia prostrate, 19.55% to Stipa hohenackeriana, 4.77% to Astragalus brachyodonuts and 20.38% to the other species. Analysis of variance showed that the production of species among years were significant (P<0.01). In terms of stability (interactions of year × month), Artemisia fragrans and Kochia prostrata were stable, with a high yield; however, Astragalus brachyodonuts and Stipa hohenackeriana were stable with a low yield.

The study of ecological areas in Ardabil province with the aim of controlling and differentiating land use and recognizing the rangeland species type was conducted in 2010-2012. According to recent surveys, the area of ​​Ardebil province is estimated to be about1,777,736 hectares. The total lands are included: rangelands and forests about 685,707 hectares (38%), cultivated lands about 1,062,924 hectares (60%), rock and bare outcrops of about 14,628 hectares, water levels of 1,186 hectares (1%) and urban and industrial lands are about 13,291 hectares (1%). 66 rangeland types were divided into four groups in the rangelands of the province as follow: Artemisia, Astragalus, perennial grasses and Onobrychis. In addition, five individual types as Peganum, Caparis-Iris, Carex-Iris, Salsola-Poa and Trifolium-Trisetum were identified. Moreover, the forest habitats of the province are composed of eight types of Quercus–Fagus, Corylus avellana Mixed, Carpinus–Corylus, Tamarix–Salix, Quercus-Carpinus-Zelkova,, Quercustype, Pistacia atlantica subsp mutica type and Crataegus-Paliurus spina – Christi- Acer monspessulanum Mixed type. The results of this research including the area and position of natural resources types as well as vegetation map can be used as a scientific document and reference for the implementation of applied research projects by executive organizations in Ardebil Province.

     Festuca sulcata L. as a perennial grass is special to semi- steppe rangelands in alpine regions. In order to evaluate the growth quality, forage and seed yields, five extensions of this species were planted under rainfed conditions in a completely randomized block design with three replications at Samian station in Ardebil. After establishment of the seedlings, traits, such as viability percentage, crown cover, shrub height, seedling vigor, and forage and seed yields were measured from 2010 to 2014, at the end of the growing season. The data were analyzed using SAS software and comparison of the means of the evaluated traits was performed by Duncan's multiple range tests at P ≤ 0.05. The results showed that the greatest percentages of crown cover (997.77 cm2), shrub height (45.88 cm) and seed viability (100%) were belonged to Sarein-Alvaris accession. Average values of forage and seed yields were 528.58 and 93.33 kg ha-1 y-1, respectively. There was no significant difference between accessions in term of seed yield but there was a significant difference (P ≤ 0.01) between years. The average seed production in the studied ecotypes was 95.33 kg ha-1. Consequently, superior accessions of this species with great potential for foliage production can be used in the process of restoration and development of semi- steppe rangelands in alpine region.

The effects of planting method and planting time on seed and forage production of Astragalus brachyodontus was investigated in the natural rangelands of Meshgin-Shahr from 2013 to 2016. The bioassay was conducted in a completely randomized split-plot design with three replications. The factor A was different planting times (autumn and spring), while the factor B was different planting methods (Seedling, row cropping and dry farming methods in the natural rangelands). Forage and seed yield were measured after growing and seedling establishment. All data were analyzed by SAS statistical software and means statistical comparison was done using duncan multiple range test. The results showed significant effect of planting time on seed and forage yield (p<0.01). Comparison of means showed that autumn planting was better than spring one. Planting method also had significant effect on seed yield (p<0.05). The highest amount of seed yield was related to row cultivation in the second year. Accordingly, planting of Astragalus brachyodontus in autumn at 1500-m height from the see level is recommended to achieve better results. In order to saving the seeds used in cultivation and creating a uniform distribution, row cultivation with a certain depth (2.5-3 cm) were recommended.

The ecological characteristics of Festuca sulcata Beck were studied in this research to examine its potential application in rangeland improvement. Five sites were selected for sampling using vegetation map, field visit based on the species distribution. In each sampling site, three 100-m transects and 10 plots (1m×1m) along the transects were selected using systematic-randomized method. The factors related to canopy cover, bush height, species frequency forage, and seed production were measured on the transects in the plots. Also some qualitative characteristics such as root system, phenology, seed quality, regeneration, preference value, and chemical composition of the plant were studied. The results showed that Festuca sulcata is distributed from 2200 to 3800 m from the sea level on acidic and alkaline clay-loam textured soils in the study area. The growth time was begun from May to the end of June and the time of ripened and seed dissemination was started from July to mid-August. In early flowering stage, the palatability was in grade I and the best grazing time was in seed ripened stage. In the post-seeding stage, the plant became woody and livestock grazing preference was reduced. Forage production yield was 528.58 kg dry matter ha-1, while seed production was 95.33 kg ha-1. Due to the resistance to cold and frost conditions, this species is suitable for restoration and improvement of rangelands with more than 350 mm rainfall.

Today, forest reserves in protecting biological diversity (plant and animal diversity) and preventing the extinction of many important plant and animal species have been of great interest. In this regard, Fandaghlou Forest reserve with an area of 913 hectares is the largest forest reserve of common hazel in the country, located in the north-east of Ardebil and around of Namin. This forest is considered as the spatial, climatic and habitat conditions, an ecotone forest from Hyrcanin to Arasbaran forests. For this reason, it is rich in vegetation diversity and composition. The common hazel (Corylus avellana L.) is the main species in Fandoghlou. The common hazel distribution in the study area is generally located at a range of 1320-1540 m.a.s.l. it occurs in both pure and mixed stands. Therefore, with increasing elevation, the number and density of hazelnut are decreased and form forest types with beech, hornbeam and oak species. There are five main forests types including mixed Corylus, Corylus – Fagus, Fagus – Corylus with Carpinus, Corylus–Qurecus with Carpinus and mixed broadleaves. The impacts of human-induced disturbances on forest ecosystem including logging, in recent years, forest conversion to other land uses, grazing, and fires have caused the destruction of the Fandoghlou Forest. Therefore, in order to achieve favorite situation, the responsible organizations must pay more attention to the conservation and protection of hazelnut habitats. Considering the national and global value of forest stands, implementation of development plans and investments to attract and dispatch tourists to the region, regardless to the forest conservation value, should be excluded, otherwise, this habitat will face irreparable damage in the future.

Preference evaluation of four species of perennial forage grasses including Alopecurus textilis L., Festuca ovina L. and F. sulcata L. and Agropyron trichophorum. In order to use for improvement and restoration of rangelands, seeds of species were collected from of Ardebil province. After seed germination test and preparing of seed bed. This eyperiment was done based on Randomized completely block design with 3 replicates in dryland conditions from 2010 -2014 in Ardabil station. After plants establishment and end of growing, crown cover Total height, seedling vigority, forage and seed production. Analysis variance of data was done using SAS software and the mean comparison with Duncan method at 5% level. The results showed that, the species in term of studied traits, had significant difference exept survival, The highest height, crown cover and forage production. Be longes to Agropyron trichophorum, The highest seedling vigority belodes to Agropyron trichophorum and Festuca sulcata finally, Therefore these con be used in improvement and developmend procces of pasture in arid and semi arid region.

Vegetation changes rangelands, that usually occurs in the composition and structure of vegetation over time. On the other hand, human factors, especially rangeland management, play an important role in maintaining stability or degradation. The purpose of this study was to investigate the dynamics of vegetation under the local management was carried out from 2008 to 1391. To do this, main vegetative stepic regions of the factors related to crown cover, density and abundance were determined by multi-year and group species, during the three transects 500 m in 30 plots (5/1 × 5/1 meter) as well as soil moisture and organic carbon were measured. The results showed that a four-year period, In the vegetation of perennial grasses, such as Festuca ovina, Alopecurus aucheri, Bromus tomentellus and Koeleria caucasica their variation was due to rainfall in the growing season, there was no significant difference between study years. In shrub cover such as Onobrychis cornuta and Astragalus aureus were significantly different between years of study due to annual precipitation fluctuations and soil moisture moisture content. In perennial forbodies, such as Scorzonera radicosa, Polygonum alpetre and Veronica orientalis were affected by precipitation seasonal and there was a significant difference between years. Changes in soil organic carbon and the process is slow. Therefore the results of the survey year to year changes in vegetation,climate changes and soil moisture also how the soil erosion condition can as an appropriate guide for the correct current methods used for management of rangeland ecosystems.

The major portion of our rangelands are located in arid and semi-arid regions. In this climate, variability of vegetation under climate change impact of balanced energy flow in ecosystems ranges vegetation is that the generally composition and structure of vegetation typically occurs over time. on the other hand, human factors and grassland management, especially crucial in maintaining its stability or degradation plays. Accordinglymonitoring vegetation winter pasture areas was conducted in Ardabil Province from 1387 to 1391. In each community a key area was determined to establish a permanent site, In each key area of the canopy cover, density and abundance during the three transects 500 m in 30 plots (1/20 × 1/20 meter) as well as soil moisture and organic carbon were measured. The results showed that a four-year period, proportional to changes in rainfall and temperature, Under local management conditions, In Moqan sites of Artemisia fragrans with absolute dominance and renewed growth. In direct response to the seasonal and annual rainfall and vegetation cover has a decisive role the results of the survey year to year changes in vegetation,climate changes from year to year and soil moisture also how the soil erosion condition can as an appropriate guide to the correct current methods used for management of rangeland ecosystems.

Rangeland vegetation dynamics can be affected by various natural and unnatural factors over time. The purpose of this study was to investigate the dynamics of vegetation under the climatic conditions and soil properties. Accordingly, data collection for evaluating vegetation dynamics in rangeland ecosystems of Ardabil province was conducted at three research sites including Moqan winter rangeland, and Nour and Aqdagh Khalkhal summer rangelands in 2009 followed for four years. Vegetation variables were measured using transects and sampling plots. Meanwhile, at the location of each plot, soil moisture was measured at two or three depths of 0-15, 15-30 and 30-45 cm using a Time-Domain Reflectometer (TDR). According to the results, in the Nour site, the changes recorded for shrubs such as Onobrychis cornuta L. and forbs were significant (P

The purpose of this study was to investigate the relationship between rangeland plants production based on total production and life forms of grasses, forbs, and shrubs with topographic factors (altitude, slope, and aspects) in Sabalan rangelands, Ardabil province. To determine the annual total production, the amount of production was estimated using harvesting method in one square meter plots (totally of 216 plots) under the altitude range of 1200 to 2900 meters a.s.l. Using topographic maps, the digital elevation model was derived and classified maps of elevation, slope, and aspect were derived. Then, in each plot, information such as elevation, slope, and aspect was extracted. The correlation between life forms and topographic factors was analyzed using multivariate regression method. The results showed that there was a significant relationship between the production of life forms such as grasses (P0.05). The production of grasses, forbs and total production had direct relationship with slope; however, the production of shrubs decreased with the increase of slope. The production of grasses increased with altitude, and in the east-faced slopes, it was estimated more than the other aspects. The production of forbs decreased with the increase of altitude and was higher in the east aspect in comparison with the other aspects. The production of shrubs and total production in the middle altitude and in north –faced slopes were more than the other classes and aspects according to the suitable ecological condition and low degradation. Although it is obvious that elevation, slope, and aspect can change and affect the production, this effect is unknown, especially in the connection with life forms and the process of change. Overall, it can be concluded that these results could be used in the management of these rangelands, particularly in the improvement and rehabilitation practices.

The current study aims to ordinate ecological groups in the wetlands of northern and eastern slopes of the Sabalan mountain and investigate their relationship with environmental variables. The location of wetlands was found using field surveys and satellite images. In total، 32 wetland sites were identified for the sampling purpose. 320 sample plots (relevé) were selected using the systematic-rondom method and their plants were classified using the TWINSPAN method. The study of vegetation cover was undertaken using the Braun-Blanquet method. The results showed that five main groups of vegetation could be distinguished، which include (i) halophyte ecological groups، (ii) mire ecological groups، (iii) wet meadows ecological groups، (iv) grass- legume ecological groups and (v) aquatic and heliophyte ecological groups. The statistical analysis showed that there were significant differences between plant groups and altitude، canopy cover percentage، pH، OC% and geophytes plant percentage at 1 and 5 percent significance level. The results of ordination (DCA) also showed that main environmental factors affecting plant groups were soil characteristics (EC، pH، dependent cations)، land form، humidity and altitude.

Excessive exploitation of pastures and intensity of grazing factors that undermine and destroy vegetation is pasture. This study aimed to determine the effects of different grazing intensity on vegetation and soil moisture in Arshaq area over four years (1386 to 1389) under three levels of grazing intensity (without it, moderate grazing and heavy grazing) Homogeneous ecological conditions of the pastures were the required components of plant and soil include: Percentage of vegetation cover, litter, bare soil and soil moisture in two root deeps of 15-0 and 30-15 cm in the adjacent plot was done within 30 transects. The results showed that total vegetation cover in the absence of grazing conditions was 36.95%, which the plants of class I, II and III had 3.54%, 18.47% and 14.94% of the total value, respectively. The average grazing conditions were 28.64% which the plants of class I, II and III had 3.16%, 10.5% and 14.98% of the total value, respectively. Intense grazing in the 28.51% Average total vegetation with the minor changes in values of the plant class I (1.58%), II (1.35%) and III (25.58%). Grazing intensity had significant effect on different plant groups (I, II, III and total) in terms of plant canopy (p<0.01). The results showed are two distinct classes of A (without Grazing) and Class B (moderate grazing and heavy grazing) between grazing intensity different. Besides, two separate group of A (plant Class I and II), B (pasturable plants of class III) and C (of vegetation) was found between the plant species.

In the northern and the eastern slopes of Sabalan mountains which has a semi-aria climate. There were several pools، and wetlands and the study of the flora in these areas is important. Identification of plants provide useful guidelines for environmental and ecological management. In this study، flora، life form and chorology the species were studied and introduced. During vegetation growth، from 2008 to 2009 we collected and identified plant species in the region، and floristic list was provided. The results showed that totally، there were 216 plant species that belonged to 128 genera and 36 families in the studied area. The flora of these regions included 216 plant species that belonged to 128 genera and 36 families. Poaceae family including 25 genera and 46 species، Astraceae family with 11 genera and 19 species، Fabaceae family with 9 genera and 18 species and Brassicaceae family with 12 genera and 15 species، had the highest number of species. Also according to the classification Raunkiaer system (Raunkiaer، 1934) there were 22%. Therophytes، 30% Cryptophytes، 46% Hemicryptophytes، and 2% Chamaephytes. From view point of plant chorology، were formed in: 44. 44% Pluriregional، 20. 83% Europa-Siberian، Irano-Turanian and Mediterranean، 15. 74% Europa-Siberian، Irano-Turanian، 3. 7% Europa-Siberian، 2. 32% Irano-Turanian and Mediterranean، 5. 56% Indemic for Iran and 7. 41% of species were not identified. Considering that the region climate affected by Siberian، Hyrkaniane and Mediterranean climate therefore the most vegetative elements in this study region belonged to Europa-Siberian and Europa-Siberian، Irano-Turanian، respectively.
