TL;DR: In this article, the authors showed that the present (anthropogenic) upper border of the forest in the mountain regions of our republic averagely passes from 1600-2000 m above sea level.
Abstract: Vegetation cover, particularly the forest being a vital component of the natural environment shows a sensitive reaction to all changes going on there and reflects in itself the situation of changed environment taken place as a result of human influence The basic reasons of negative transformation of the forest ecosystems are - destruction of forests and formation instead of their places agrocenoses, lawlessly felling of trees, speedily development of cattlebreeding (over grazing the cattle in the forest), soil melioration, use of fertilizers and chemical substances, fire accidents, extraction of mineral resources, etc The transformation of forest ecosystems in separate zones of Azerbaijan has taken place differently depending on the physical-geographical conditions, then intensity and direction of anthropogenic influence as well Our researches showed that the present (anthropogenic) upper border of the forest in the mountain regions of our republic averagely passes from 1600-2000 m above sea level, ie the upper border of the forest (UBF) was descended 500-1000 m down The biological varieties of thin groves of the subalpine type crooked trunk, low shapely birch (Betula pendula), service-tree (Sorbus) and eastern oak (Quercus macranthera) degradaded and in their places appeared anthropogenic type meadows, steppes and bushes as a result of descending of UBF Because of anthropogenic influence the beech forests existed in the middle mountain forest belt became thin, then their productivity decreased and they were replaced by hornbeam (Carpinus caucasia) groves and bush groups (juniper (Juniperus), hazelnut (Corylus) and different bushes) The pure oak (Q iberica) and oak − hornbeam forests in the lower mountain-forest belt (Georgian oak belt) of Major and Minor Caucasus being thinned became underwood origin groves and replaced by oriental hornbeam (Carpinus orientalis) generated from lower productive shoots and xerophil type shibliaks (Christ's thorn, Spiraea, juniper bushes, etc) In many parts of Minor Caucasus the biological diversity of the forest was completely annihilated and replaced by agricultural areas, seliteb landseapes and wormwood semi- deserts The plain forests are met in Ganykh-Eyrichay valley, Samur-Devechi and Lenkaran plains and alongside areas of Kur-Araz rivers in our republic The forest landscape has mainly dominated in Ganykh-Eyrichay valley and Lenkaran plain up to the near past Only separate small areas of these forests are preserved They have been substituted by different direction spheres of man's economic activity and gardens Once, untill the middle of the XVIII century the tugay forests stretching 900 km distance alongside of the Kur river up to the Caspian Sea occupied a wide strip in the territory of our republic Now they are preserved as small tracts shape separately from each other

TL;DR: In this paper, the authors pointed out that the problems of desertification and degradation in relation to climate warming and due to the increased anthropogenic impact on biomes and ecosystems can lead to a large number of ecological problems and disasters.
Abstract: The main ecosystems and biomes of CA are of global significance, and include deserts, steppes, montane temperate forests, montane coniferous forests, alpine and sub-alpine meadows, river deltas and riparian forests, flooded Tugay type of forests and freshwater wetlands. The region is rich in biodiversity since it extends in the core of Eurasia continent with natural crossroads of species migrating in different directions depending on natural obstacles and corridors. Particularly rich in biodiversity are the mountains of CA. As to the forested landscapes, the region during 1990–2015 experienced the smallest gain/reduction in the forested land area; however, forested area monitoring is conducted with some disturbances. The illegal cutting of trees and fuelwood harvesting as well as conversion of forest land to agricultural farming all led towards decrease in the forested areas of the CA region. On the other hand, the anthropogenic factor and its different activities are becoming more and more important in CA countries: long-term land use under agriculture, irrigation or intensive grazing supported the increase in soil salinization, contamination and the drastic changes towards the worsening of biodiversity of natural ecosystems there. These negative tendencies are evident in nearly half of all natural pastures in whole arid zone. The attempts to protect endangered species and entire ecosystems have been evident during the last years in the CA region. Tajikistan is distinguished by the highest percentage of total protected areas. The problems of desertification and degradation in relation to climate warming and due to the increased anthropogenic impact on biomes and ecosystems can lead to a large number of ecological problems and disasters in CA countries. The Aral Sea area and its surroundings are one of these hotspots.
