Armenia is an ancient country. The ancestors of modern Armenians lived on the Armenian plateau over a vast territory, between Asia Minor and the Iranian upland. Human footprints detected in the area go back to the Old Stone Age. During the Palaeolithic period there was primitive farming on the plateau, and in the Neolithic and the early Bronze Age, animal husbandry developed. Armenia is one of the ancient centres of metal culture/industry; already in the 5^th - 4^th centuries BC there was copper working in Armenia. Between the 3^rd and 2^nd centuries BC stock-rearing became a major occupation. The tribes of the Armenian plateau unified to create unions like Uruatri, Nairi, Dayani, and others. Based on these unions the state of Urartu was created, which at the end of ninth – eighth centuries BC considerably expanded its boundaries. In the seventh – sixth centuries BC, in the valleys of the Armenian mountain ranges, crop production and viticulture were largely developed. On a Babylonian world map (fifth century BC) Armenia was included and in the second half of the second century the Armenian nationality was finally shaped.

Being between the greatest conflicting powers of East and West (Persia, Rome, Arabic Caliphate, Byzantium and others) Armenia became an arena of incessant war-fare. It strove for independence for many centuries. In the fourth century BC the basis of the Armenian state was strengthened. Later Christianity was declared the state religion and Armenian national culture flourished. With the emergence of the Dynasty of Bagratids (tenth century) and the Armenian State of Kilikia (eleventh century) medieval society prospered, and the full flowering of its national attributes occurred. In the 12^th century Armenia was divided between Turkey and Iran. In the course of the three succeeding centuries Armenians were involved in a liberation movement against the Turkish-Persian powers.

At the beginning of the nineteenth century Eastern Armenia joined Russia. However a large part of its territory remained under the sovereignty/control of Turkey. On November 29, 1920 Armenia was declared a Soviet Socialist Republic. After the collapse of the Soviet Union in 1991 Armenia regained its independence.

The majority of the population are Armenians. In addition there are Russians, Yezidis, Azeris, Georgians, Kurds, Greeks, Assyrians, Ukrainians, Jews and others. According to the World Factbook the July 2006 population was estimated at 2,976,372 with a growth rate of -0.19%.

Geographical location Armenia is in the south of the Caucasus, latitude 38⁰ 51´ to 41^o18´ North and longitude 43^o29´ to 46^o37´ East. It occupies the south-eastern part of the Armenian mountain range and the central part of the Small Caucasus. To the north it is bordered by the Republic of Georgia, to the east and south-west by the Republic of Azerbaijan, to the west by Turkey and to the south by Iran. The territory is divided into 37 regions, which after gaining independence in 1991, were regrouped into 10 regions, the so-called "marzes": Aragatsotn, Ararat, Armavir, Gegharkunik, Lori, Kotayk, Shirak, Syunik, Tavush and Vayots Dzor. The capital of the country is Yerevan.

The total land area is 297, 000 sq km and it is 270 km wide and 279 km long. The total area of agricultural land is 1,391,377 ha, 494,689 ha of which are arable, 63,766 are perennial plantations, 138,907 ha are grasslands and 694,015 ha are pastures.

Livestock. The total number of cattle in 2001 was 497,300 (Table 2) of which 264,900 were cows; also there were 540,000 small ruminants, 68,900 pigs and 11,400 horses. In 1998 some 462,000 tons of milk, about 86,000 tons of meat and 1,922 tons of wool were produced. This production was not sufficient for domestic needs and some products were imported from abroad (Iran, Turkey, India, United Arab Emirates, etc.). By 2004 livestock numbers were 565,800 cattle (including nearly 300,000 cows), 628,500 small ruminants, 85,400 pigs and 12,500 horses; production was 535,831 mt of fresh milk, 54,027 mt of meat and 1,200 mt of wool. Imports of meat and milk in 2004 had increased to 31,051.2 mt (total meat) and 53,962.5 mt (milk equivalents) respectively (Table 3).

For full details of livestock numbers and imports see section 4. and Tables 2 and 3.

Topography. Armenia is the most mountainous of the Caucasian republics (see Figure 1). It is distinguished by its complex relief and varied natural conditions. The average altitude is 1,800 m. More than 90 percent is above 1,000 m. The highest point, the top of mount Aragats, is 4,095 m while the lowest point is at 380 m in the north-east where the River Araks flows out of Margi gorge.

Figure 1 – Map of Armenia

The diverse shapes and types of mountainous relief are conditioned by the complexity of geological structure as well as by physical and geographical conditions. The prevalence of volcanic relief is a characteristic feature. It is represented by mountain ranges (Kharabakh, Javakhet), shield-shaped ridges (Gegam, Vardenis) and large isolated cone and dome-shaped ridges (mountains Aragats and Arayee). A substantial area is occupied by folded ridges: Pambak, Areguni, Murkhuz, Zangezur, having different directions and extensions. Low mountains and foot-hills are fragmented by a dense network of ravines and gorges and mudflow creeks. On the whole the relief of the republic is complex and fragmented, and with many landslides and active erosion processes, tillage and agricultural activity is hampered.

Soils. Soil cover is very varied. Here all kinds of zonal soil types, shaped in mountainous districts of the Great Caucasus, can be encountered. Throughout the territory there are 5 classes, 15 genetic types, 33 pseudo/sub-types, several hundred appearance/form types of soil as well as soils of 135 origins. Zonal expansion is characteristic of 8 (types) out of the identified 15 genetic types. They occupy 91 percent of the territory. The remainder is covered by intra-zonal and azonal soils.

The most common of the zonal types are: mountain-meadow, mountain-meadow-steppe, mountain brown forest-soil, mountain chernozem, mountain chestnut and mountain-brown soils. In the areas where zonal types of soil were formed, the intrazonal types are also spread: fluvial-swamp, fluvial-grassland, irrigated meadow-brown, meadow-chernozem, turf-carbonated soils. Despite apparent vertical zonality being characteristic of soil cover, all soil types depend on the altitude of the district.

The vegetation is represented by many types, from steppe and semi-steppe to alpine. The diversity of species covers two extremely different floristic provinces: Ponto-Girkanic mesophyl and Iranian xerophyll. The vegetation of the lower zone is semi-steppe with expanded halophyte vegetation in steppe areas with the prevalence of Artemisia in semi-desert areas.

In the foot-hills of the Ararat valley frigonoid vegetation with a predominance of thorny shrubs that form hummocks, (Astragalus, Acantholimon), as well as xerophythe undergrowth perennials from the family of labiates are commonest.

Higher up, where the mountain-steppe zone starts, the vegetation is Stipa and Festuca. In some of the more arid parts xerophyll- mixed grass vegetation is mixed with tragacanth (Ferula) steppes.

Most of the north-east and south-east region is forest, which explains the comparatively regular climatic conditions. Together with shrubs, forests comprise 12 percent of the territory. The altitude of forests in the north-east reaches 1,900-2,100 m, in Zangezur – up to 2,400 m and comprises mainly eastern beech, oak, and hornbeam. Xerophyll sparse woods, juniper and deciduous forests are widespread.

Above the tree line, sub-alpine, alpine and nival vegetation is common. Mountain-meadow steppes, sub-alpine and alpine meadows serve as summer pastures. High mountains and the tops of the mountains are tundra. On stony talus and alluvia, sparse cushion-vegetation grows. There are some glaciers.

Water resources are rivers, lakes and underground water (see Figure 2). Annually rivers bring in six billion m³ of water. An appropriate use of this amount would suffice to irrigate the low and foothill regions. The northern river network drains to the Caspian sea and includes about 450 rivers and streams extending for more than 10 km. Rivers of Southern Armenia drain to the basin of the River Araks (about 74 percent of the river net).

Figure 2 – Water resources of Armenia

Maximum floods occur in May, by September they become less. Most rivers in their lower stretches are subject to mudflows, and sudden and intense floods especially in spring. These are accompanied by the washing down of a huge amount of mud and stones. Because of the fast flow rivers do not freeze. Seasonal distribution of river flow is uneven. Thus, the flow in the cold half of the year from September to February is only 25 percent of the total, while that in the warmer half is 75 percent. The flow in the warm season is distinguished by a substantial variability.

The biggest and deepest river is the boundary River Araks which stretches through Armenia for only 200 km. Its major tributaries in Armenia are the Akhuryan, Hrazdan, Azat, Vedi, Vorotan, Vokhchi, Megri, etc. The River Sevjur is remarkable for being mainly fed by underground water. The rivers of the Koor basin have their source in the northern, damper part of the country and are consequently deeper. One of the largest tributaries of the River Koor in the Republic is the River Debed formed by the joining of two rivers, Dsoraget and Pambak.

There are more than 100 minor mountain lakes, most of them above 2,000 m, that typically are used for watering pastures. Lake Sevan is of national significance (about 35 billion m³), its water being intensively used for irrigation and energy generation. Among minor lakes, the following: Arpa, Akna, Lori, and Cars have been used recently not only for irrigation but also for fish farming.

Swamp and marshlands are mainly in the north-west of the Lori plateau, Shurabad basin, Masrin and Ararat valleys; most have already been drained and are used for agriculture. In the north of Armenia swampiness is favoured by high rainfall, a flat land surface and the presence of underground water, while in the south it is favoured by the ancient river-beds of the River Araks.

Armenia is on the northern edge of the sub-tropical zone, in latitudes characterized by a manifestly arid and continental climate. Due to a complex mountainous relief the climate is very varied. For example, the Ararat valley has an arid continental climate, however only 10 km to the north – on the mountain of Aragats – mountain tundra with glacial formationscan be observed.

Solar radiation, the most important climate factor, is very intense. At noon in the Ararat valley, each cm² of the surface receives on average 1.46 calories of heat per minute. The intensity of solar energy increases in line with the increase in altitude. At 3,000 m it increases to 1.54 cal/cm². The annual duration of sunlight in the Ararat valley and Sevan basin reaches about 3000 hours; in the mid-mountainous forest areas of the north – about 2000 hours.

High fluctuations in annual and daily temperatures are characteristic of the climate. In July-August in the lowlands, air temperature is about 22-26° C, in mid-mountainous country – 16-20° C, in the highland zone it does not pass 10° C; the absolute maximal temperature ranges from 42° to 20°. In January, depending on the altitude of the territory and the peculiarities of the relief, the mean daily temperature ranges between +1° and -13°, absolute minima range from –20⁰ to –45⁰ C. Large daily temperature fluctuations occur in summer in the Ararat valley where the air temperature rises to +42^o C in day-time, and falls to +20^o C at night.

The relief greatly affects the duration and the features of the seasons. The frost free period in the lowlands and the foothills is more than 220 days, in mid-mountainous areas about 150 days, and in highland zones 60 days. The longest season in lowland regions is summer (4-5 months), in mid-mountains the seasons coincide with calendar seasons, while in the highlands winter lasts for six months.

The highest precipitation is between May and June. The annual precipitation fluctuates over a wide scale: from 250 mm, in arid regions, to 1,000 mm in the highlands. The distribution of snow cover is also unequal. In the foothill zone of the Ararat valley a stable snow cover is not observed every year and its height does not exceed 10 cm, whereas in the highlands the duration of stable snow cover is 5-6 months and its height reaches 2 m.

Changes in the direction of air flows are conditioned by the very rugged relief, so the republic is distinguished by diverse wind speeds and direction. The strongest winds are in the highlands in winter. In summer, mountain-valley winds appear in the valleys and hollows. To sum up, Armenia has a vertical zonality and diversity of climate.

The republic is subject to vertical zonality, the latter being very varied. Abrupt changes of natural zones go in line with altitude changes. The following agro-economic natural zones can be defined (see Figure 3):

Semi desert zone. The semi-desert zone occupies the Ararat valley and the lowlands adjacent to the foothills. It also occurs in small tracts in the south-east at altitudes between 600 to 1,300 m. A major characteristic of the semi-desert zone is low precipitation, not above 250 mm, and high air temperature. Limited precipitation coupled with the influence of high temperatures creates xerothermic conditions.

Figure 3 – Natural zones of Armenia

The hot summer and dryness of the air result in rapid evaporation of soil moisture, which in turn leads to salt accumulation in the soil upper levels. Semi-desert soil cover varies according to its composition, salt level, physical characteristics, steepness, etc. Semi-desert is extensive within the complex relief. Absolutely flat land, as well as slopes of different steepness and exposures can be found. In semi-steppes all changes in vegetation are conditioned by relief changes.

Since the climate is continental there is no dense and lush natural cover. The vegetation is mainly represented by two extremely different eco-types – xerophytes (Hordeum crinitum, Kochia, Euphorbia marschalliana, Astragalus, Bromus inermis, Androsace, Festuca sulcata, etc.) and ephemerals (Bromus tectorum, Bromus squarrosum, Androsace, Geranium tuberosum, Hordeum crinitum, etc.) and ephemeroids (Poa bulbosa, Chenopodium humile, Carex stenophilla). In areas of intense salinisation – solonetz or alkali soil – the vegetation is Salsola.

The basic vegetation is Artemisia, turf grasses (Bromus tectorum, Bromus squarrosum, Hordeum crinitum, Festuca sulcata), ephemerals (Bromus tectorum, Bromus squarrosum, Androsace, Geranium tuberosum, Hordeum crinitum, etc.) and ephemeroids (Poa bulbosa, Chenopodium humile, Carex stenophilla). Semi-deserts mostly serve as pastures for cattle and small ruminants.

Natural environmental conditions: heat, light and ground salt, favour the development of horticulture and fruit growing in this area which suits cultivation of excellent types of grape, apricot, peach, etc., which cannot be grown in other zones. Farming is all irrigated.

The steppe. Occupies a substantial territory at an altitude of between 1,000-2,200 m. The relief is extremely complex. Here all kinds of transitions can be found: from mountain plateau to plain, from slight and flat slopes to steep and abrupt ones. In some parts the relief is complicated by uneven landscape with multiple minor ridges of various size and shape.

The climate is mainly dry and warm. In terms of temperature effects, two sub-zones can be identified: the upper or moderately warm sub-zone, situated at an altitude above 1,800 m and the lower or warm sub-zone, characterized by a higher temperature in summer and by a longer duration of the growing period. The annual precipitation is 450 mm to 600 mm. Annual distribution of precipitation is uneven. The maximum precipitation level is in spring and the beginning of summer. July and especially August are very dry. The continental climate is conditioned by comparatively high temperatures in summer and low temperatures in winter. The soil cover is particularly varied with frequent transitions from light chestnut to chernozem.

Among steppe vegetation groups dry-steppe and genuine steppe vegetation can be identified. Turf grasses prevail within the vegetation cover of dry steppe. Typically the grass is not high; it is sparse, and of pasture type. Steppe plant groupings are characterized by a well-developed turf-forming processes and intense growth of mixed forbs, grass, Achillea, Circium, Euphorbia, Alchemilla, Taraxacum, etc., and legumes (Vicia, Trifolium repens, Lathyrus, etc.); in the spring ephemerals are more abundant. Nevertheless turf grasses predominate among steppe vegetation. They determine the character of steppes at the end of summer and the beginning of autumn.

The steppe zone is typically agricultural. Major crops are grains – wheat, barley, and oats. Here livestock-raising and fruit-growing is also well developed. Crops are both irrigated and rain fed: in the lower sub-zone it is irrigated, in the upper sub-zone field crops can be cultivated without any irrigation. Steep land is used for fodder production and pastures; pastures prevail.

Steppe-meadow zone. At certain altitudes steppes change into steppe-meadows. They form a transition between the steppes and meadows and are characterized by features that are common to both steppe and meadow phytocenoses. Steppe meadows occupy a considerable territory at a range of 1,500 – 1,800 m above sea level, in some parts the altitude reaches 2,000 – 2,300 m. They are remarkable on account of extremely diverse vegetation. The correlation between steppe and meadow vegetation varies, depending on the type of the steppe-meadow. In lower parts, steppe plants (sheep’s fescue – Festuca sulcata, Phleum phleoides, Agropyron, Bromus, etc.) are predominant, while in higher parts, meadow vegetation (Phleum pratense, Dactylis glomerata, Festuca pratensis, etc.) prevails. The grass cover is dense.

The climate differs from the climate in steppe areas by a damper and warmer summer in the case of a comparatively even distribution of precipitation during the vegetation period. In the lower sub-zone the unevenness of precipitation levels is rather apparent. The annual precipitation level exceeds 600 mm, in the upper zone it reaches up to 700 mm. In summer, thunderstorms accompanied by hail are frequent. The frost-free period continues for up to 4 – 4.5 months. Frosts start from September and last till the end of May.

Soil types are varied. There are various mountain chernozem and mountain meadow soils. On the plains and lesser slopes melkozem soils are distinguished by a high production level. Rarely, rocks of original types, like crags, cliffs and alluvial deposits are encountered. Steppe-meadow zones, as well as the steppe zones are mainly agricultural. Because of a damper climate, crops are rainfed. The main crops grown are cereals, potato, perennial and annual grass etc. Uncultivated land is used for grazing and fodder. Steeper and stonier slopes are used only for grazing.

The forest zone. Armenia is less well endowed with forest than the other republics of the Caucasus. Its forest area comprises 411,000 ha, about 288,000 ha of which are actually covered by forests. Forests are unevenly distributed: they mainly occur in two regions. The first is the larger, situated in the north-east. In other regions forests can also be encountered in the form of small islands. The central part of the country is almost without forest. The composition of forests is diverse and rich. Among the most common trees the following should be mentioned: Quercus, Fagus, Carpinus, Tilia, Acer, Ulmus, Fraxinus, Carpinus orientalis, Betula, Pinus, Juniperus. The major forest trees are Fagus, Quercus and Carpinus. Forests are typically in the mountains and valleys. In the lowlands, plains, and plateaus there are none at all. The steepness of forest slopes ranges from 20-25° to 30-35° and above.

Being mostly in mid mountains and foothills, forest regions occupy a moderately cold, climatically-speaking, mountain strip. The climate is characterized by comparatively small annual fluctuations: 22-24° C; mean annual temperature ranging from 4 to 9° C and mean precipitation level – from 400 to 800 mm. Winter is very gentle; the mean temperature in January being 1-2°.C. The climate of southern Armenia is especially arid, since the upper forest border is of significantly high altitude. The mountains are at an altitude of 500 to 2300 m. However, in some regions forests are situated at an altitude of 2600 m and above.

Cleared forest zone. Incorrect forest felling in the past and the overuse of forest have radically reduced forest area. Cleared forest lands are either abandoned or used as grasslands and pastures. The incidence of cleared forest zones is directly linked to the incidence of forest itself throughout the country. An especially large area of cleared forest occurs in northern Armenia. A small expansion of the zone within the southern part of the country is explained by climatic and relief peculiarities of this part. The climate here is arid, the relief is highly rugged, forest slopes are steep and abrupt. The combination of these characteristics leads to the fact that after de-forestation these areas are converted into steppes and mountain xerophytes but not into meadows.

The cleared forest zone mostly occurs on comparatively gentle reliefs, on mild slopes; the reason for this being the fact that more available (in terms of relief) forests have been logged by the population. In regions with rugged landscape, cleared forest extends over very different relief conditions and is often on steep slopes.

Sub-alpine zone. At an altitude of 2,300 to 2,800 m a distinctly definable zone is situated on all significant mountain ridges and tracts. The borders here referred to are rather vague. They merely identify the region where there is the maximum development of sub-alpine meadows. Sometimes in damper regions, along northern slopes, it descends to an altitude of 1,900 m; in dry regions of central and especially southern Armenia on the southern slopes of certain mountain tracts distinctly defined sub-alpine meadows are encountered only at an altitude of 2,700-2,800 m. The grass Phleum pratense, Dactylis glomerata, Festuca pratensis, etc. is tallish, the natural cover is dense with a high level of turf formation. Geological stages are apparent. The high location results in climate severity. Summer here is moderately cold and brief; already at the end of August there are frosts. Annual precipitation levels exceed 650 –700 mm. Moderate slopes and plains are rare. The sub-alpine zone, situated on Zangezur ridge and its spurs is especially remarkable for its rugged relief and steep slopes.

The soil of the sub-alpine zone resembles the mountain-meadow type and is distinguished by a greater capacity and considerably high level of humus and dead roots. As a result of severe climate and sparse vegetation, seasonal farming and cultivation of field crops are excluded. Sub-alpine meadows are mainly for mowing. Only areas on very steep and stony slopes are used as pastures.

The alpine zone occupies a vast territory and is pronounced on all more or less significant mountains. It is found at an altitude of 2,700 to 3,500 m. On northern slopes it may descend to 2,500 meters, whereas on southern slopes it can ascend above 2,900 m. Environmental conditions of the alpine zone are unique. The relief is diverse. Along with broad plains, situated on high plateaus, multiple steep slopes of various ridges and cones can be encountered. There are many parent rocks and outcrops here. A considerable territory on major mountain slopes is occupied by rubble scarps and embankments (talus), fixed and in motion.

The climate is distinguished by its severity. Short growing period, rarefied air, abrupt variations of temperature between day and night (in summer), considerably high level of (atmospheric) precipitation, and winds are the basic characteristics of the alpine climate.

Alpine meadow soil is characterized by a substantial level of humidity, especially in spring and autumn. Large sheets of snow, melting throughout the whole summer, nourish rivers and streams. In northern high areas and sheltered depressions, large sheets of snow remain from the previous autumn. On many mountain ridges the rugged relief does not allow the melt to flow down to the lower zones. The stagnation of these waters in higher parts for a long period of time results in the emergence of rather large lakes. The highland zone Aragats is especially rich in lakes. Here one can encounter not only sheets of eternal snow but also huge glaciers. Severe thunderstorms accompanied by massive hail are very common during the vegetation growing period. Night frosts can occur in any summer month. Even in July and August, in the higher alpine zone, cases of snow falls (melting instantly) have been observed.

Farming in the alpine zone is impossible, since no field crop could grow in such severe environmental conditions. Mowing of most vegetation is not possible either because of the short vegetation height. Thus, alpine meadows with pasture characteristics serve as an important natural fodder base for livestock-breeding in summer.

Considering the natural and economic conditions, as well as production specialization, nine agricultural zones can be identified. Generally, an agricultural zone represents a production-area combination, specialized in certain types of agricultural production, distinguished by a specific combination of agricultural activities and land use.

The zone of Ararat valley is specialized in wine production, vegetable and fruit-growing, plus well-developed dairy and meat production, and poultry keeping on an industrial basis. A considerable part of the zone is considered to be a suburb of Yerevan which affects the distribution and specialization of agricultural production. The major part of the zone is characterized by homogeneous climatic conditions. It represents a plain at an altitude of 800-1000 m surrounded by mountains on most sides. This is a zone of irrigated crop husbandry, with highly developed agricultural production, remarkable for its high productivity per hectare.

The foothills of the Ararat Valley are a zone of viticulture and fruit growing with developed dairy and bovine meat production, pig-breeding and poultry-keeping on an industrial basis. The population living high in the mountains is involved in sheep-breeding, cereal crops and tobacco cultivation. The central zone has a developed dairy and beef industry and sheep breeding. Depending on its climate the zone is divided into: dry-steppe (1,400 – 1,800 m) and mountain-steppe (more than 1,800 m above sea level). Field husbandry is typically rainfed; animal-husbandry produces 55 percent of the total agricultural production of the zone.

The Sevan basin is a zone of stock-breeding and potato growing. The leading occupation among stock-breeding activities is dairy and beef production and meat-wool-dairy sheep-breeding. In the lower part of the zone at 1,400 – 2,100 m field husbandry is mostly irrigated. At 1,400 – 2,500 m rainfed field husbandry prevails. At an altitude above 2,500 m there are open grazing lands.

In the north-eastern zone tobacco cultivation, cattle breeding and fruit growing prevail with developed viticulture and pig-breeding. The zone is represented by two sub-zones: woodless plain, situated up to 900 m and mountain-forest – more than 900 m.

Lori-Pambak is a dairy and livestock-breeding zone with developed potato-cultivation. There are two sub-zones in Lori-Pambak: mountain-forest (up to 1,500 m) and mountain-steppe (more than 1,500 m). This is mostly a zone of rainfed farming.

Shirak is a zone of dairy and beef production and meat-wool-dairy sheep-breeding with developed grain growing. Shirak occupies the north-western part of the republic. The zone is divided into two sub-zones: dry-steppe and mountain-steppe, situated at an altitude of 1,800 m and more than 1,800 m respectively. In the first sub-zone farming is mostly irrigated, in the second sub-zone it is rainfed.

Daralagyaz is a zone with developed viticulture and fruit-growing.

Zangezur is a zone of cattle-breeding and sheep-breeding with developed tobacco cultivation and viticulture. Zangezur occupies the south-western edge of the republic. The zone is divided into three sub-zones: lowland, (up to 1,400 m), wooded steppe (1,400-2,000 m) and mountain-steppe (more than 2,000 m).

The total grazing land area is 832,922 ha (see Table 4), of which grass lands occupy 138,904 ha and pastures 694,015 hectares. All the grasslands are of the mountain type. A great diversity of climatic conditions has created vertical transition of the vegetation. Pastures and grass lands are zonally allocated in semi-desert, steppe, steppe-meadow, post-forest, sub-alpine and alpine zones. Within each zone there are also azonal grazing lands (such as swamps with excessive moisture), their total area being about 8,700 ha.

Predominant zonal types of grasslands are sub-alpine ones. They comprise about 37 percent of total grass land. Then come post-forest– 23 percent, steppe-meadow – 22 percent, etc.

Predominant zonal types of pastures are again sub-alpine meadows. They occupy about 33 percent of the total pasture area. These are followed by steppe-meadows – 20 percent, alpine – 18 percent, post-forest – 14 percent, steppe – 11 percent and semi-desert – 5 percent.

The typological composition of grass lands and pastures is extremely diverse. It is conditioned by vertical zonality. The formation of natural mountain grasslands and their vertical location is influenced by the relief, the altitude and slope steepness, shape and exposure. A significant impact on changes in highland vegetation is caused by human interference: grazing, mowing, fodder production, irrigation and other practices have altered the nature of grassland and pasture vegetation to such an extent that currently there is no way to tell indigenous types from secondary ones. Numerous highland bio-climatic factors creating a vertical zonality for vegetation develop a great diversity of natural types of grass lands and pastures.

Semi-desert range lands occupy the Ararat valley and the enclosed foothill plains. They can be encountered on a small scale in other regions as well at an altitude of 500 – 1,300 m. This zone is characterized by an insignificant precipitation level (200 – 300 mm), an uneven seasonal distribution of the latter, high temperatures in summer and low in winter; thus preventing the vegetation from fully exploiting the potential soil fertility. This results in the fact that semi-desert vegetation is not dense. The vegetation is represented by two major divergent ecological types: xerophytes (Chondrilla, Hordeum crinitum, Kochia, Euphorbia marschalliana, Astragalus, Bromus inermis, Androsace, Festuca sulcata, etc.) and ephemerals (Bromus tectorum, Bromus squarrosum). In areas, where highly saline soils – solonetz and solonchak – are formed, the vegetation is represented by halophytes.

The basic vegetation is Artemisia, turf grasses (Bromus tectorum, Bromus squarrosum, Hordeum crinitum, Festuca sulcata), and ephemeroids (Poa bulbosa, Chenopodium humile, Carex stenophilla). Semi-deserts are mainly used for grazing and serve as spring-autumn and winter pastures for sheep. The total area is over 36,000 ha.

Steppe lands occupy a substantial territory at altitudes between 1,000 to 1,500 m and sometimes up to 1,800 m. The relief of this zone is extremely varied: gentle slopes, plateaus, valleys, as well as steep and abrupt slopes can be encountered. The climate is typically dry and warm.

Among steppe groups dry-steppe lands and genuine steppe can be identified. Turf grasses are predominant in the vegetation of dry steppes. Abundance of ephemerals in spring grass cover is a characteristic feature of dry-steppe groupings. The grass is typically low, sparse, of pasture type. As a rule the soil is very stony and compacted, less melkozem with low capacity, brown or chestnut. The total area of dry-steppe groupings comprises 22,100 ha.

Grazing lands on indigenous steppes occupy extended territories at an altitude of 1,200 to 1,500 m sometimes up to 1,800 m. They appear on plateaux with well developed and high capacity melkozem soil, also on steep and slight slopes; this resulting in diverse and vari-coloured vegetation types. Steppe groupings are characterized by highly developed turf-formation processes, and extensive development of mixed grass and legumes; in spring, ephemerals are more or less abundant. Nevertheless turf grasses predominate, affecting the appearance of steppes at the end of summer and the beginning of winter. The total area of steppe groupings comprises about 77,100 ha.

Steppe-meadows occupy considerable areas at altitudes between 1,500 – 1,800 m sometimes up to 2,200 m and more. The climate of this zone is distinguished by a comparatively damp and less warm summer, and more equal distribution of precipitation levels in the vegetation period. In summer there is frequent hail. The frostfree period lasts for 4-4.5 months. Steppe-meadow vegetation creates a clearly defined zone in almost all mountainous terrains. It is more vivid in southern-facing slopes but it can also be encountered on slopes with other exposures. Steppe meadows are particularly developed on slighter slopes, sometimes they emerge on plateaus with almost flat relief. The total area of steppe-meadow groupings is about 169,300 ha.

Cleared-forest grazing lands are encountered predominantly under gentle relief, on flat and gently sloping areas, in regions distinguished by intersecting relief and often on large steep slopes. The grass cover is dense, with different tiers, comprising both meadow species (Rumex acetosa, Cephalaria tatarica, Agrostis vulgaris, Trifolium pratense, Trifolium ambiguum, Poa pratensis, Koeleria gracilis, Dactylis glomerata, Phleum pratense, etc.) and forest species (Vicia balansae, Deschampsia caespitosa, Arrhenatherum elatius, Agrostis planifolia, Agropyron caninum, Festuca gigantea, etc.). Meadow species are typically predominant. Sometimes meadow species are mixed with forest shrubs or grass. Forest trees: Quercus, Fagus, Carpinus, Tilia, Acer, Ulmus, Fraxinus, Carpinus orientalis, birch – Betula, Pinus, Juniperus etc. Nevertheless, beech, oak and hornbeam can be met in almost all types of cleared -forest grasslands. The total area comprises 128,400 ha.

Sub-alpine grazing lands occupy a considerable territory and are the major lands in the country used as grasslands and pastures. Both are used in all seasons except winter. It should be mentioned that the tall vegetation (Phleum pratense, Dactylis glomerata, Festuca pratensis, etc.), are used in summer for hay, while the short ones (Festuca ovina, Bromus inermis, Koeleria, Taraxacum, etc.) are used from spring till autumn for grazing.

The sub-alpine zone represents a clearly defined zone at an altitude of 2,200 – 2,800 m. The relief of this zone is diverse: slight and steep slopes, often abrupt ones can be encountered. The climate is montane, the average annual temperature fluctuates from 5⁰ to 2⁰ and below. Annual precipitation level is 800 – 900 mm. The highest leve
