Quantitative description of forest stands in terms of the composition and species diversity is used as one of the most important tools in forest management. This research investigates the composition and species diversity of the coppice with standard stands of Arasbaran forests. In order to carry out this research, 24 rectangular sample plots with an area of ​​half a hectare (with dimensions of 50 meters by 100 meters) were randomly surveyed in the study area. Inside these samples, the structural characteristics of the stands, including the species, Coppice shoots, the diameter and the height of the sprout-clump, were measured using the 100% statistical method. Shannon-Wiener diversity index, Margalf richness and Pylo's uniformity were used to check biodiversity. The results showed that Carpinus betulus L. (63.8 percent) was the dominant species and Quercus macranthera (26.7 percent) and Acer campestre (4.5 percent) were among the species with the highest abundance. The average height and DBH were 6.45 meters and 12.14 cm, respectively. The highest and lowest values ​​of the biodiversity index are related to the Pylo index (1.01) and the Margalef index (0.71). The research showed that the diagonal distribution of the stand indicates that the stand is of the same age and young, and the bell shape of the height distribution also indicates the accumulation of the most searches in the middle altitude classes.

This research was conducted in 2020 in order to investigating the species diversity and abundance of oribatid mites in the oak and hornbeam forests of Arasbaran (Ahar and Kaleibar) in East Azerbaijan Province. Soil sampling was carried out in May and June. Oribatid mites present in soil samples were separated using Berlese funnels and clarified in relative solution, followed by preparation of microscope slides. After identification, counting, diversity and evenness indices (Shannon and Simpson), as well as species richness were calculated using Ecological Methodology 6.0 software. In general, 29 species of Oribatid mites from 27 genera and 23 families were identified in this study: Cosmochthonius lanatus Michael, Sphaerochthonius splendidus Berlese, Steganacarus (Tropacarus) carinatus Koch, Papillacarus pseudoaciculatus Mahunka, Rhysotritia ardua Koch, Nothrus biciliatus Koch, Hermanniella septentrionalis Berlese, Plesiodamaeus ornatus Pérez-Íñígo, Belba sp., Xenillus setosus Grobler, Ozman & Cobanoglu, Fosseremus quadripertitus Grandjean, Rhinoppia obsoleta Paoli, Ramusella (Ramusella) puertomonttensis Hammer, Ramusella (R.) sengbuschi Tokyoensis, Ramusella (R.) sengbuschi Str., Graptoppia (G.) sundensis acuta Ayyildiz, Rectoppia sp., Suctobelella sp., Austrocarabodes (Austrocarabodes) foliaceisetus Murvanidze & Weigmann, Tectocepheus velaus Michael, Eupelops acromios Haman, Berlesezetes aegypticus Balogh & Mahunka, Oribatula (O.) tibialis allifera Subías, Protoribates (P.) paracapucinus Mahunka, Scheloribates fimbriatus Thor., Ceratozetes conjunctus Mihelčič, Punctoribates angulatus Bayartogtokh, Grobler & Cobanoglu, Galumna sp., Pilogalumna sp. The highest abundance of mites in Ahar and Kaleibar belonged to Scheloribtes fimbriatus and Oribaiula tibilis, respectively. The calculated species diversity indices in the Kaleibar region during June were higher than those in May. The diversity and species richness of oribatid mites were higher in Kaleibar with oak vegetation, which could be due to the higher humidity and acidity of the soil compared to Ahar.

Plant endophytic fungi play an important role in the physiological and biochemical interactions of plants in response to environmental conditions and by producing specific secondary metabolites. In addition to preserving the host plant, they also gain economic importance. In this regard, the identification of endophytic fungi of Arasbaran Cotoneaster integerrimus shrub was targeted. Leaf and stem samples were isolated from the plant and, after surface disinfection, were cultured in a PDA medium containing Streptomycin. After growing fungal hyphae and culturing them, the PDB medium was used to continue the work. To identify the grown fungal, DNA extraction was performed and Polymerase Chain Reaction was performed using Internal Transcribed Spacer (ITS) primers. PCR results showed that out of 15 isolated isolates, the ITS fragment was amplified in 9 isolates. As 3 isolates in Penicillium sizovae, three isolates in Alternaria alternate, two isolates in Penicillium and the last isolate were not named due to the low similarity of its ITS sequence with the database data and it is probably a new species and needs further studies. Phylogenetic analysis identified the four species in two completely distinct clades, so that the lowest genetic distance observed between the two Penicillium species and the maximum distance observed between the Penicillium sp and Fungal sp. The present study is the first report on Cotoneaster integerrimus endophytic fungi and shows that this plant hosts a small number and range of endophytic fungi.

Knowing the habitat conditions of forest species is one of the primary principles for understanding forest ecosystems. This research aims to study the quantitative and qualitative characteristics of wild cherry (Cerasus avium L.) in ‎different aspects and elevations, and determine the most important ecological factors affecting ‎these characteristics. The study area is Kalibar Chay and Ilgenhe Chai of Arasbaran forests in ‎Kalibar county. According to the physiographic conditions of these regions in two elevation classes, ‎‎1000-1500 and 1500-2000 m.a.s.l., and in three main geographical aspects (north, east and west), 30 ‎circle sample plots with 500 m2 were selected in wild cherry habitats. Characteristics of wild cherry such ‎as physiographic features, diameter at breast height (DBH), origin, trunk quality and canopy diameter with a diameter ‎of more than 6 cm were recorded in each sample plot. Also, soil samples were taken ‎to determine some soil properties. Results showed that the DBH of trees in the altitude range of ‎‎1000-1500 m.a.s.l. is significantly higher than the altitude range of 1500-2000 ‎m.a.s.l. It can be concluded ‎that wild cherry stems have higher growth potential in terms of elevation class at low altitudes ‎and in terms of soil conditions in deep soils and high drainage with medium moisture retention ‎capacity. It was also found that the mean of both DBH and crown diameter and the density of wild cherry in the northern ‎and eastern aspects are higher than in the western aspect. Generally, wild cherry in this region prefers the northern and eastern slopes.‎Analysis of Relevance and Redundancy (RDA), Arasbaran, elevation, geographical aspect.

Rowan or mountain ash (Sorbus aucuparia) has been studied less in terms of biological and silvicultural characteristics. Given the little information about the rowan species and the high ecological importance of this species and the lack of information about the habitats of this species in Arasbaran and the quantitative characteristics of this species, this study aims to address the lack of information required about this species to provide management solutions and improve the habitat of this species.

In the study area, 18 half-hectare sample plots with dimensions (50 × 100 meters) and a total of nine hectares were selected and surveyed. The selection of sample pieces was systematic randomized so that the first sample pieces were randomly and the next sample plots were selected at a distance of 800 m from each other in the eastern direction. All trees in the sample plot were surveyed in order to determine the percentage of rowan species compared to other species in the sample plots.

Results showed that there were 20 species in the sample plots. Quercus macranthera (1018 stems per hectare), Viburnum lantana (290 stems per hectare) and Carpinus orientlais (226 stems per hectare) were the three most important species in terms of abundance in the study area. Sorbus aucuparia species was observed along with the mentioned species in the region and showed the fourth rank in terms of average density per hectare (142 stems per hectare). The average diameter at the breast height (DBH) and height of the measured tees stems were 9.8 (±6) cm and 4.4 (±1.8) meters, respectively. The highest number per hectare was observed on slopes less than 40% and at altitudes above 2200 meters above sea level. There was a significant statistically difference in the values ​​of DBH with slope classes. There was no significant difference between the height of trees and the frequency per hectare with the slope of the land.

According to the results, considering the role of rowan in the stability of sloping areas and reducing erosion, by increasing the conservation period and exclosure of valuable forest species, including various species of Sorbus sp, long-term results will be accessible in the protection of Arasbaran plant ecosystem.

Tourism development by planning the principles of access roads can help the management and development of villages in natural and protected areas. This study aimed at planning and developing the access roads to achieve the tourism and rural areas as the recreational attractions in Arasbaran protected area. For this purpose, the road network options were designed for three different scenarios to access the recreational and rural areas in GIS environment and evaluated in terms of technical, environmental and socio-economic aspects. In the next stage, the existing road network was modified according to the optimal-designed road options. Finally, the modified versions of the existing road network were proposed for tourism development and management in the region. Thus, the variants of the existing road network, the optimal-designed road network and the modified-road network were evaluated and compared. Moreover, among the designed options, the 10th option in three different scenarios to access the recreational areas and the minimum, medium, and maximum villages with densities of 4.17, 4.93, and 5.86 mha-1, respectively, was chosen as the optimal option to modify the existing road network. Finally, the modified road networks with densities of 3.98, 4.66, and 5.55 mha-1 and accessibilities of 72.7, 76.19, and 78.33 percent were proposed for these three scenarios. According to assessment and comparison of the variants, the optimal-designed road networks and the modified road networks were identified as the better alternatives compared to the existing road network. Tourism management and development in Arasbaran by principled planning and development of access roads can lead to prosperity of economic activities and improve the rural development in this area.

Woody debris as an important part of forest ecosystems plays a vital role in ecological performance. The quantitative and qualitative status of wood waste in forest areas is affected by various factors, one of the most important of which is the effects of human communities and the history of wood waste exploitation. So far, a study on the status of wood debris as an important and vital element in forest ecosystems and also the role of changing the pattern of fuel consumption as the most important factor affecting the status of wood waste, which is one of the most important sources of fuel needs in Arasbaran is counted, it has not been done. Since proper evaluation of the these programs can be helpful in the proper planning and management of forest resources, this study aims to investigate the effects of fossil fuel providing on the woody debris component as fuel wood in terms of the quantitative and qualitative charactristics in Arasbaran forests.

Two villages including Makidi and Kalasur were selected as using fossilfuel and fuelwood areas, respectively. In so doing, three one-hectare sample plots in the square form and a total of six hectares were implemented in each area. Some characteristics including species type, diameter, height, and decay class of woody debris (standing, fallen and stumped) were measured in each sample plot.

The results of Mann-Whitney test showed the amount of woody debris in the fossilfuel and fuelwood areas are significantly different (p < 0.05). The amount of density and volume of woody debris was estimated to be 418 numbers per hectare and 3.42 cubic meters per hectare in the no harvesting fuel wood area and 50 numbers per hectare and 0.22 cubic meters per hectare in the harvesting fuel wood area.

The results of this research indicate the success of the fuel consumption pattern changing of forest dwellers in preserving woody debris in Arasbaran forests.

 

The Arasbaran vegetation community is an important source of biodiversity and one of the biosphere reserves in the northwest of Iran, which is influenced by different climates and special importance due to variations in altitude. Since an altitude is an environmental characteristic that affects the habitat of plant species, this study aimed to investigate the ecological role of altitude on the quantitative characteristics of caucasian oak trees (Q. macranthera Fisch. & C.A.Mey. ex Hohen.) and determine the best range for the natural growth of this species in Arasbaran forests. Three oak stands were selected in three altitude ranges including low (1200-1400 m a.s.l.), middle (1400-1600 m a.s.l.) and high (1600-1800 m a.s.l.) altitude. At each altitude, three plots were sampled with one-hectare area, and the quantitative characteristics of all trees, including diameter at breast height, basal area and trees canopy diameter were measured. Normality of data was verified by the Kolmogorov-Smirnov test, and the comparison of the mean of the characteristics was done using one-way ANOVA at a probability level of 0.05 and Duncanchr('39')s test. The results showed that there was a significant difference in diameter of the trees, the height of the trees and basal area per hectare among the three altitudes, but density per hectare had a significant difference between the first and second altitudes.  In addition, the canopy coverage had no significant difference among the three altitude ranges. The middle altitude was more favorable condition stand in terms of its quantitative characteristics. Therefore, the results of this study indicated that the middle altitude (1400-1600 m a.s.l.) is a more suitable habitat for caucasian oak species in Arasbaran forests, and doing more protection of the stands in this altitude can be created a seed bank for the production of high quality seedlings and forest plantations in the region.

The main objective of this research is to study the production of Ribes biberistentii (reddish blackberry) and its role in rural household`s economies of the Arasbaran region. This research was carried out using library references and field surveys in the summer of 2018 in the Arasbaran forests. A questionnaire was used to collect data on socio-economic from 32 harvesters of Kalasur village in Ilgeneh chay watershed of Arasbaran. The collected data were about fruit price, type and method of processing, amount of harvest and consumption of raw and processed fruit, sales and marketing, and medicinal uses. Pearson correlation analysis was performed between different tree characteristics and fruit production. The results showed that the weight of 1000 fruit of reddish blackberry was 240 grams. Fruit production of this species had the highest and positive correlation with the average crown diameter (0.767) at 0.01 significant level. The results showed that its fruit had medicinal uses to treat high blood pressure by local peoples. Concerning the price of raw fruit and the amount of harvest, the economic value of fruit harvested for the entire households was 192 million rials at 2017. The average annual economic value of harvesting and selling of reddish blackberry for each household was about 6078 thousand rials.

The aim of this study was to investigate morphological diversity and canonical correlation analysis between four environmental variables (altitude, slope, latitude, longitude) and 10 plant characteristics (collar diameter, number of sprouts, diameter at breast height, main stem height, large crown diameter, small crown diameter, leaf length, leaf width, leaflet length) in sumac (Rhus coriaria L.). Plant samples were selected from five geographical locations with unique features in two provinces of East and West Azarbaijan. According to the results of descriptive statistics, the highest coefficients of variations were observed for diameter at breast height (61%), number of sprouts (52%), collar diameter (40%) and the lowest one was observed for leaf width (21%). The highest sprout was found in the plants sampled from Nizhdarreh that can be due to its bad growth conditions. Canonical correlation analysis revealed that with increasing the amounts of latitude and reducing the amounts of slope and longitude, the length of leaves increases.

This research was carried out for investigating the effect of environmental factors on plant types in Arasbaran forests. To do so, for considering of the different conditions, sampling was carried out based on the landform units, and the size of a squared sample plots, 400 m2 was determined by the minimum surface area method. According to the landform units of the study area, 27 plots were established and after recording the existing data in each plots, the soil samples were collected. Then, using PC-ORD software and Cluster analysis, vegetation of study area were classified and after that, Principle Component Analysis and XLSTAT software were used to analysis relationship between vegetation and environmental factors and determine the most important factors. Regarding to Cluster analysis, six plant types were identified and some species such as Quercus macranthera Fisch. & C. A. Mey., Carpinus betulus L., Pyrus glabra Boiss., Berberis vulgaris L., Prunus cerasifera Ehrh., Palliurus spina-chiristi Mill., and Mespilusgermanica L. were dominant species of plant types. Also, the results of the PCA analysis showed that silt, potassium, porosity, bulk density, phosphorus and clay are the most effective factors on distribution of plant types in the study area. Considering that use of plant species in restoration of a region needs data on their habitat demands, so results of this research could be use in restoration of same regions.

Juniper (JuniperusfoetidissimaWilld.) is classified as a Least Concern (LC) species of the International Union for Conservation of Nature (IUCN), but its distribution has decreased as a flagship and longevous species in East Azarbaijan province during last decades, and hence it is important to protect its habitats. In this research, the habitat suitability of Juniper in Arasbaran biosphere reserve, as the only habitat of this species in Iran, was considered. For the habitat suitability modeling of this species, Ecological Niche Factor Analysis (ENFA) method and ENFA software were used. Results showed that this species has narrow ecological niche and is sensitive to habitat changes. Information layers determined as affecting variables on this species include slope, aspect, elevation, land form, Geology and climate. Results showed that 27.17% of Arasbaran biosphere reserve were suitable for Juniper. The suitable habitats were recognized to be in areas with elevation range of 330 to 1500 meters above sea level, 10 to 60 percent of slope, hillsides, mediterranean and semi-arid climates. The results of this research is suitable for sustainable management of forest ecosystems, reclamation and land protection.

Arasbaran Biosphere Reserve is the ninth Biosphere Reserve in Iran with a total area of 78759 hectares in northwest of Iran. Most of it is forest, pasture and agricultural lands. The difference between the height of 265 m and 2868 m above sea level, the presence of physiographic, soil and microclimates have created different habitats that have made its unique flora richness. Vegetation of lowlands of this area was carried out using Braun-Blanqet method. Data analysis (releves and plant species) was performed based on the Corrospondence factorial analysis (AFC) method in anaphyto software. In the lowlands of the Arasbaran Biosphere Reserve, Five associations and four subassociations including 176 taxa have been identified, of which 7.9% are phanerophytes, 8.5% chamaephytes, 25% hemicryptophytes, 4.5% geophytes and 54% terophytes. Considering the global importance of this Biosphere Reserve for flora, vegetation and fauna, its further conservation is recommended as a natural heritage for the future.

Getting informed about of land uses patterns and knowing the changes of each land use, during the time is the one of the prerequisites for the correct uses of land. During the last decades many methods of this regard have been developed. One of these methods is the use of landscape metrics. Landscape metrics are quantitative indices that describe compositional and spatial aspects of landscape. The most important impose on these studies is that changes into landscape patterns strongly affected landscape function. Due to the special ecological position of the Arasbaran biosphere, and some destructive factors such as over-grazing, high acreage of agricultural fields and encroachment of human-made structures into natural ecosystems, the area has witnessed a noticeable rate of land degradation during the last decades. For this reason the main objective of this study was analysis of land use and land cover changes using ecological landscape metrics. At first, the multi temporal Landsat images dated 1990, 2002 and 2014 were provided. Based on former knowledge from study area and study aim, satellite images were classified in seven classes including high forest, low forest, agriculture, grassland, barren land, water and urban area. For quantitative landscape metrics for each land use map, we used Fragstate software. Selected metrics included CA, PLAND, NP, LPI, MN_SHAPE, ENN, IJI, DIVISION and SHDI. The result of calculating CA, PLAND and NP metrics showed that forests were degraded and urban area and barren land were extended. Decreasing the index of the largest patch (LPI) and increasing indexes of contagion-interspersion (IJI), ENN and DIVISION for forest area indicates the destruction and disintegration of these lands. In landscape level the number of patches has increased over the time, which represents the intensity of negative and defamatory change during the study. Also, the increasing of Shannon's diversity index confirms the increasing diversity of patches in the regions as a result of increasing patch numbers and changes in landscape. Contribution of each category in altering other LULC categories was also calculated to provide an improved understanding regarding current LULC change processes in the area. Grassland is the most invasive category against low-density forest such that it occupies this category for 815 and 1,219 hectares during both time intervals, respectively. The result of calculating metrics and change detection showed the changes in the second period (2002-2014) were more intense than the first period (1990-2002). Based on the results can be mentioned that during of study the landscape in Arasbaran region completely fragmented. Also consider spatial diversity and dispersion of land uses, there is a possibility of degradation and land use change in the future. Accordingly, there is a need to develop a suitable program to prevent unwanted changes in the landscape and maintain its spatial continuity. Development in the future should be programmed based on sustainable development principles and attention be pay to protection, maintenance and ecosystem management.

Analysis of the structure of tree species provides a complete information on species diversity, composition, spatial distribution in mixed natural forests. It helps to better understanding of many ecological and silvicultural issues in order to optimal management of the ecosystem. The main objective of this research is to investigate the differences and similarities of sites with different conservation history (Kalale and Vaygan Sites with a long-term conservation history and Kuran Sites with a short-term conservation history) in terms of diversity and composition of the tree structure in Arasbaran forests. For this purpose, nine hectares with one-hectare sample plot were inventoried with full-callipering method. The measured characteristics were type of species, distance and azimuth of each tree from the last tree, diameter at breast height (DBH), tree height. The spatial pattern of trees was determined by the modified K-Ripley function. Based on the results, 14 species were observed in the three study areas. Four species of hornbeam (68 %), maple (8 %), yew (7 %) and persian oak (2.5 %) composed of about 88% of the total density of trees. Kalale site (15.29 m2) and Kuran (0.26 m2) had the highest and lowest basal-area per hectare, respectively. Kalale and Vaygan sites had a wide range of diameter classes in comparison with the Kuran site. L function showed that almost all species had cluster distribution and only hornbeam had a random distribution in Kuran site. Therefore, every intervention in order to tending reclamation andenrichment of the studied stands should be based on making species mixture and keeping clustered spatial pattern and also it should be avoided pure species reforestation to ensureboth biodiversity and sustainability of stands

Sumac (Rhus coriaria L.) is a multi-purpose indicator species in Arasbaran region, especially in Horand County and a remarkable amount of its fruits is traditionally exploited every year. This research was focused on the quantitative evaluation of production and the economic importance of sumac in the household's economy of Aghboraz Village of Horand County. The data were collected in two parts, including the quantitative evaluation of fruit production via random-systematic sampling strategy and socio-economic analysis about harvesting, selling and processing of sumac via semi-open questionnaire. Based on the results, the average number of sumac stem per hectares was 3928 and its average yield was estimated 428.16 kg per ha. Sum and average of harvested sumac by rural household was 8455 kg and 422.75 kg, respectively. The average annual harvest value of households was 46500 thousand Rials. The average annual household income from raw and processed sumac was estimated 7740 and 46480 thousand Rials, respectively. The average share of household income from the sumac harvesting was 44% of total household income varied from 0.9% to 100% among different households. The average added value created by processing was 332500 Rials. According to the results, it can be concluded that sumac species can be effective in improving the economic situation of the villagers.

Knowledge on silvicultural characteristics of forest stands is prior to any forest management practice. The objectives of this study were to determine the forest types and to explore some quantitative and qualitative characteristics of Arasbaran forest protected area along an altitudinal gradient. Therefore, circular plots of 400 m2 at 50-meter elevation intervals were established along five altitudinal transects, 100 meters apart, from the lowest (1100 m a.s.l) to the highest (1725 m a.s.l) forest limit. In each plot, the physiographic conditions including slope gradient, altitude and geographic coordinates were determined. Woody species were identified and the diameter at breast height (dbh) of all trees above 7.5 cm dbh, as well as origin, health status, number of stems and tree leaning were measured. In addition, the regeneration frequency of each individual tree taller than 1.30 m in three diameter classes (0-2.5, 2.5-5 and 5-7.5 cm dbh) and shorter than 1.3 m in three height classes (0-10, 10-50 and 50-130 cm) were examined within 100 m2 regeneration plots. Four forest types including Carpinus betulus - Quercus petraea (1100-1400 m a.s.l), C. betulus - Q. petraea - Acer campestre- Fraxinus excelsior (1400-1500 m a.s.l), C. betulus - Q. petraea - A. campestre (1500-1650 m a.s.l) and C. betulus - Q. macranthera (1650-1725 m a.s.l) were distinguished along the altitudinal gradient. The highest number of stems per ha (mature and regeneration stands) and average basal area were observed in C. betulus - Q. macranthera type, whereas the highest average dbh was recorded in C. betulus - Q. petraea forest type. Finally, seed regeneration was most common in C. betulus - Q. petraea - A. campestre forest type.

Arasbaran forest is one of the most important and valuable economic and tourism region. Ecotourism development in these forests requires comprehensive and detailed plans to consider all aspects of ecotourism development and maintain the sustainability of the ecosystem to be managed. This project aimed at considering all these merits needed for an appropriate method. In order to achieve a pre-defined process, the analytic network process method was used. The results of rating the control criteria showed that economic benefits with weight 0.26 are the most important criterion in the development of ecotourism in the study area followed by the economic opportunities and environmental costs with weights 0.205 and 0.142, respectively. The benefits of socio-cultural, environmental risks, opportunities, socio-cultural, environmental opportunities, and economic risks, the risks of socio-cultural, environmental benefits, environmental benefits, economic costs and expenses socio-cultural with weight of 0.088, 0.078, 0.069, 0.064, 0.025, 0.0194, 0.0189, 0.016, and 0.0126 were the subsequent priorities. The results of a comprehensive review of the development of ecotourism showed that ecotourism development can have significant environmental costs and opportunities in Arasbaran region that should be considered in its development management.

Today, tourism plays an important role in the global economy. Among the different types of tourism, community-based ecotourism development is an appropriate strategy for preserving natural resources and cultural values. This development is possible through empowerment of local communities and causes the cultural, the social and the environmental stability. In the present study, group decision making approach was used in order to rank the strategic criteria affecting the development of community-based ecotourism in Arasbaran. According to the judgments of experts, strategic criteria affecting the development of community-based ecotourism determined and they were weighted using pairwise comparison analysis. The results showed that most of the identified strategic criteria were related to the weaknesses of laws and management, the strengths of natural resources, social strengths and threats of natural resources respectively with 9, 8, 7 and 6 criteria. The number and weight of strategic criteria related to the social strengths and opportunities revealed in Arasbaran region there are much good potential in the field of community-based ecotourism development.

Cornelian cherry grows naturally in Arasbaran forests and a plenty amount of its fruit have annually been exploited in traditional manner. This study aimed to determine the cornelian cherry fruit production and the relationship between vegetative characteristics and amount of fruit production for three consecutive years. For this purpose, as cornelian cherry habitat, the forest stand by 50 hectares in Kalaleh village in North West of Iran (Arasbaran region) was selected. To determine cornelian cherry fruit production per hectare, the number of cornelian cherry stems per hectare was determined along 15 transects with distance of 100 m apart from each other. To estimate fruit product, a number of 45 individuals of cornelian cherry were selected and then marked along transects with randomized systematic method. Then, for three years, similar vegetative characteristics: total height (m), crown height (m), crown diameter (m), diameter at breast height (mm), diameter at collar (mm), number of coppice shoots and fruit product (gr) were measured annually. Mathematical model regression to determine relationship between the measured vegetative characteristics and fruit production per stem were established. Then Fruit product per hectare was calculated given the number of stems per hectares. According to survey results, the mean number of Cornelian cherry was calculated 530 individuals per hectare. Average fruit production in three consecutive years, respectively 446.97, 318.69 and 253.37grams for each trees. Also was found that three characteristics: canopy diameter, diameter at collar of the main stem and number of coppice shoots were significantly correlated with the fruits product. These three characteristics can be used as crucial factors in the management and silviculture operations of the forest in order to increase the fruit production.
