For the past 200 years the forest area has become twice as less. In 8-9th century the present area of Azerbaijan was covered with 35 percent of forests. At present forests of Azerbaijan constitute 1290 thousand ha or 11% of the territory. This indicator constitutes 41% in Russian Federation, 38% in Latvia, 37% in Georgia. 48,8 percent or 592 thousand ha falls in the share of the Great Caucasus region, 14,5 percent or 176 thousand ha belongs to the Lesser Caucasus region, 2,5 percent or 30 thousand ha pertains to the Kura-Araz lowland, 0,5 percent or 6 thousand ha refers to Nakhichevan Autonomic Republic.
The forest density ratio in Azerbaijan is 0,12 ha per capita. It should be pointed out that 261 thousand ha of forest area refer to the territory which has been occupied by Armenia. Armenians who have slovenly intents present very rare flora species, trees and bushes of the Garabagh land, and even Shusha's Kharibulbul flower as belonging to them at exhibitions in European countries. There is a particular significance of forests that have been handed to us by the destiny in the prevention of fertile soils from washing off, reducing torrents to the minimum, the protection of plains from winds and drought.
Forests play a kind of a role of humidity accumulator and gives origin to a multiple number of mountain rivers and regulate the allocation of water over lowlands and plains.
In addition forests prevent from landslips and avalanches in mountainous regions. At the same time forests possess phytonsit abilities; they secrete phytonsits that kill harmful microorganisms. Forests also protect from harmful effects plants, soil, water reservoirs, roads, human settlements, memorials, and natural factors, change microclimate, reduces the effect of dry, hot, and severe winds. Forests reinforce valleys, ravines, and shifting sands, facilitate an even distribution of snow cover and its gradual melting, reduce evaporation and lower the level of ground waters.
In addition to all the aforementioned the foremost role of forests in the environment is that they as a powerful pump are capable of drawing in 10 to 20 tons carbon gas per one hectare per year and releasing oxygen in return. One hectare of forest area absorbs 8 kg of carbon gas per hour and that is equal to the amount of carbon gas breathed out by 200 people per hour.
Forests protect soil from erosion, prevent from the decline of water resources and purifies air from sanitary hygienic viewpoint, and play an indispensable role in particles exchange and biological turnover of energy.
By enumerating all this our intention is to help comprehend how crucial the issue of forest protection and reforestation are.
Northern-eastern slopes of the mountain chain of the Great Caucasus are deemed to be vast forest areas of Azerbaijan. These forests start from the Azerbaijanian territory and stretch up to the border of Dagestan. In northern eastern part of Azerbaijan forest encompasses the administrative regions of Guba, Gusar, Davachi, Siyazan and Khizi towards southwest. From the Khizi region towards southwest forest tracts gradually decline and are completely replaced by drought areas. In the macro slope of the Great Caucasus within the territory of the Shamakhi region forest tracts emerge again and form continuous cover along the slopes up to the border of the Republic of Georgia. Here forests mainly cover the area pertaining to the mountainous part of the Ismailly, Gabala, Oghuz, Shaki, Gakh, Zagatala and Balakan regions. The forest tract stretches uninterruptedly by the southern slope towards west up to the border of Georgia.
One of the vast forest areas are also the slopes of the Lesser Caucasus mountainous chain. Forests cover the northern, northern-eastern, and eastern slopes of main foothills in the shape of single tracts here. Only in the area of the Southern Garabagh the forest tract is interrupted and does not reach the Iranian border. Besides, forests can be met in the form of small islands on the slopes of Kukudag of the Shahbuz region in the Nakhichevan Autonomic Republic. One of the vast forest tracts also cover slopes of Talish mountain. Here forests are spread over the areas of the Astara, Lenkoran, Lerik, Masalli, Yardimli, Jalilabad and partially Bilasuvar regions. A lesser part of forests stretches along the Kura and Araz rivers and occupies a belt-shaped area in the form of Tugay tract.
Azerbaijan has gained a world-wide fame for its amazing beauty, rich natural resources, flora and fauna diversity. 4500 species of higher plants incorporated under 125 orders and 930 taxa are spread here. Of them 450 species of trees and bushes related to 48 orders and 135 taxa occur in forests of Azerbaijan. This constitutes 11 plant species in the flora of the Republic. 70 regional endemic species can be found in the dendroflora of Azerbaijan. This is meant to be 16% of all tree and bush species of plant.
Despite such a richness of dendroflora of Azerbaijan main forest generating species are in decline. Azerbaijan forests are composed of mainly broadleaf species. Coniferous forests that occupy a lesser area of the Great and Lesser Caucasus mainly consist of Garmagvari pine (Pinus hamata). It is sometimes called Koh (P. Kochioana) or Sosnovski (P. Sosnovi) and can be found in the Lesser Caucasus in forests around Shamlig and Boyuk Gishlag villages in the area of the Tovuz region in Gey Gel and in the Great Caucasus in the Gusar region.
At the Eldar Oyughu mountain in an area of 400 ha one can find Eldar pine (Pinus eldaricas) growing in kserofit conditions mainly in new and humid pistachio forests consisting of Garachohra (Taxus bacaata) in combination with broadleaf species or in the form of small forests. Such small forests are found in the Great Caucasus in the Hamzali cemetery of the Gabala region, in forests of the Piriguli and Oghuz region, in Khizi, and forests named Dahar foothills; in the Lesser Caucasus they can be met in Gey-Gol, Gadabay forests, Talish Mountains, and in forests around Hamazat village of the Lerik region.
Of the coniferous forests the most widely spread are Juniper forests. In the Azerbaijan forests Gazakh juniper (Juniperus Salina), Elongated juniper (C. oblonqa), jirtdan juniper (C. puqmaca), Small juniper (C. depressa), Red juniper (C. policarpos) and other species of juniper grow. The vastest area of juniper is in Bozdagh, in Nakhchivan forests there are sparse juniper forests the areas of which are not so wide.
Coniferous forests (juniper and pine) constitutes 1,6 percent of the territory covered with forests. There no evergreen broadleaf forests in Azerbaijan. Such species are only found in parks and gardens of settlements in Baku, Ganja, Sheki, Sumgayit and other big cities and communities. Forests of the Republic are mainly composed of deciduous broadleaf forests. Forest areas categorized with regard to prevalent species are distributed approximately as follows: Pine- 0,3, juniper - 1,3, pistachio - 31,9, oak - 31,5, hornbeam - 22,4, goyrush - 0,9, aghjagayin - 0,3, bushes - 2,2, birch - 0,14, govag - 0,81, gizilaghaj - 0,82, lime-tree - 0,10, other species - 8,06. Despite the forests being very diverse in composition broadleaf forests are generated mainly by pistachio, oak and hornbeam. These three species constitute 85,8 percent of the territory covered with forests.
The allocation of forests with regard to age is also various. Thus, young forests comprise 11,2 percent of the territory covered with forests, middle aged forests constitute 63,3 percent and premature forests constitute 13,4 percent and mature and old forests make up 12,1 percent. According to the information of 1996 mature and old forests constituted 35,4 percent of the territory covered with forests while in 1998 this figure become 12,1 percent. As regards middle aged forests 21,6 percent of 1996 reached 63,3 percent in 1998. This demonstrates the process of gradual rejuvenation of forests. Most of the forests of Azerbaijan by being located on steep mountain slopes are very significant in terms of soil reinforcement, water purification and climate betterment.
The allocation of forests with regard to location is also various. Thus, forests of the southern slope of the Great Caucasus occupies an area of 142,18 thousand ha, forests of the northern-eastern slope of the Great Caucasus cover an area of 352,69 thousand ha, Talish mountains ossupy 108,22 thousand ha, Garabagh forests encompass 230,04 thousand ha, the macro-slope of the Lesser Caucasus constitutes 110,22 thousand ha, the Kura-Araz lowland covers 44,04 thousand ha and Nakhichevan occupies an area of 1,93 thousand ha.
Wood capacity in pistachio forests is 59,73 million cubic meters, oak forests is 27,97 million cubic meters and hornbeam forests is 26,22 million cubic meters. The overall wood capacity of mountain forests is 110,92 million cubic meters or 81,4 percent.
The allocation of forests with regard to their density is also various. 13,7 percent of forests in the Republic refer to ones of low density (0,3-0,4), 2,62 percent refer to ones of middle density (0,5-0,6), 18,3 percent are of normal density (0,7-0,8) and 2,62 percent refer to forests with high density (0,9-1,0). The average density of forests has been defined as 0,56.
The allocation of forests with regard to Bonitet classification is also various. Forests with high I-II bonitet level constitute 14,9 percent of the area covered with forests, 42,3 percent are forests with III bonitet level, 27,4 percent are forests with IV bonitet level and forests with low V bonitet level make up 15,4 percent.
The average annual growth level of forests is 1,74 cubic meters. This growth accounts for 1,77 cubic meters in hard leaf taxa (pistachio, oak, hornbeam, etc.) and 2,12 cubic meters in soft leaf taxa (govag, yalangoz, gizilaghaj).
Based on the above said we can conclude that high productivity trees (I-II bonitet) in our forests constitutes the minority (14,9 percent). Middle productivity trees (III bonitet) comprise 42,3 percent and low productivity trees (IV-V bonitet) make up 42,8 percent. These indicators are the evidence of unsustainable approach of forestry measures relating to forest protection and the enhancement of their productivity for the past years.
Azerbaijan forests are also famous for its non-wood resources. In our forests there 150 species of wild fruit plants relating to 35 taxa. These plants produce thousand tons of wild fruits (walnut, apple, peer, zogal, sour plum, azgil, persimmon, chestnut, hazelnut, blackberries). 30 percent of these fruits are of consumption significance.
There also favorable conditions for the development of bee farming in our forests. At present there more than 1000 bee families that are bred in our forestry units. Bees help with the pollination of plants, provide good harvest of seeds and the extraction of honey.
There are also specific natural features of forests with regard to the altitude of their location. Thus, on slopes stretching towards north oak-hornbeam forests prevail. There are low productive oak, garaaghaj, demirgara forests at a low mountain altitude, relatively higher productive oak-hornbeam forests at a middle mountain altitude, and high productive oak-pistachio-hornbeam forests at a high mountain altitude. In the place where forest upper border adjoins the sub-alpine altitude low productive birch forests and short pistachio forests having curved stems are found.
Such natural features pertains to Talish mountains, mountains of the Great and Lesser Caucasus.
