Tajikistan
State of the Environment Report - 2000
Total area of the State Forest Reserves
in Tajikistan is 1,8 million hectares, including lands of local forest
authorities - 1,79 million hectares, lands of local agricultural authorities -
90,1 thousand hectares, lands of other authorities - 9,9 thousand hectares. From
this area, arboreal-scrub vegetation covers 380-400 thousand hectares, which is
23% of the State Forest Reserves. Outside of area of the State Forest Reserves,
there are fragmentary forested lands within the pastures and remote regions
totally up to 100 thousand hectares. Consequently, forests cover just 3-3,5% of
Tajikistan’s area. Total volume of timber in all forests is estimated as much as
5,7 millions m3, while annual increment makes 12-16 thousand
m3. Area of forests with tree density 0,6 and higher is just 15-20 %
from total forested area.

Forest resources of Tajikistan consist
of 200 species of trees and bushes, including rare, relict and endangered
species. Tugai forests, broad-leaved forests, birch and poplar mixed forests,
xerophytic pistachio light forests, haloxylon forests and juniper forests are
the mayor types of national forests.
Tugai forests grow in the hot flooded lowlands of
Tajikistan, alongside riverbanks and islands on the average elevation from 300
to 600 meters above sea level. Tugai forests consist of poplar Populus
pruinosa, oleaster Elaeagnus oxycarpa, tamarisk Tamarix laxa
in combination with reed grass, liana, bulrush and other plant species. Tugai
forests are well preserved in the lower reaches of Vahsh river within “Tigrovaya
balka” nature reserve as well as in Panji, Kafirnigan and Zeravshan rivers.
Tugai forests are characterized with high level of groundwater position,
periodically flooded areas during spring season, humid microclimate with high
annual surface air temperatures. Tugai forests play big water security and coast
protection functions and serve as habitats for many species of animals and
plants. Tugai forests fall to the forests of 1-th category and subject to the
strict protection.
Broad-leaved forests in Tajikistan are situated at the
altitudes from 1200 to 2500 meters above sea level and consist of temperate and
moisture-loving broad-leaved trees with predominance of walnut Juglans
regia, maple Acer turkestanicum and apple-tree Malus
sieversii.
Broad-leaved forests in Tajikistan are usually mixed with roses and
bushes. They mainly occur on the southern slopes of Gissar mountain ridge as
well as on Darvaz ridge and Peter Primus ridge, in upper reaches of Yahsu and
Kizilsu rivers. Average timber volume of Tajikistan’s broad-leaved forests is 90
m3/ha; natural increment about 0,9 m3/ha while average
tree density is 0,5. Mountain brown humidified soils, abundant precipitation
1000-1500 mm/year, mean air temperature +11° C +13° C are vital conditions for sustainable growth of
Tajikistan’s broad-leaved forests. These forests restrain avalanches, stop
erosion and flooding, prevent landslides, regulate runoff and form local
climate. They are sources of timber and raw resources. Broad-leaved forests are
extremely rich in biodiversity. More than 40 species of mammals (brown bear,
wild boar, badger, fox, wolf, ermine, jackrabbit, Siberian ibex and etc), 200
species of birds and 10 species of reptiles inhabit this area. Broad-leaved
forests fall to the forests of 1-th category and subject to the strict
protection. Just sanitary cuttings are authorized here.
Small-leaved forests grow within Tajikistan’s mountain
rivers at the altitude from 2300 to 3500 meters above sea level and consist of
trees with predominance of white willow Salix alba, Tian-Shan birch
Betula tianschanica, Tajik poplar Populus tadschikistanica and
Pamirs poplar Populus pamirica, tamarisk Tamarix laxa, black
currant, etc. Herbal cover consists of various plant species such as sedge,
clover, alfalfa, astragal, blue grass, etc. Small-leaved forests cover
Badahshan, Zeravshan, Gissar-Darvaz, and partially East Pamirs i.e. all
Tajikistan’s areas. Small-leaved forests spread within valleys of Panji, Vanch,
Yazgulem, Bartang, Gunt, Muksu, Obihingou, Zeravshan, Fandaria, and
Iskanderdaria rivers. Average timber volume of Tajikistan’s small-leaved forests
is 60-150 m3/ha; natural increment about 3-8 m3/ha while
average tree density is 0,5-0,7. The area of small-leaved forests is 10-12
thousand hectares. Small-leaved forests have important coast protection, water
security, mudflow preventing and ecological value. Small-leaved forests fall to
the forests of 1-th category and subject to the strict protection. Just sanitary
cuttings are authorized here.
Juniper forests are evergreen low productive forests and
light forests consisting of various juniper-tree species and they occupy biggest
area among all other types of forests in Tajikistan. Main tree species in those
forests are Juniperus semiglobosa, Juniperus turkestanica and
Juniperus seravschanica. In high-mountain areas on the altitude 3500-3700
meters above sea level there are rare grounded subspecies of Juniperus
turkestanica. Juniper forests accommodate honeysuckle, dogrose and other
bushes. Herbal cover consists of various plant species such as fescue, sagebrush and other
flora. Main juniper areas in Tajikistan are located on Turkestan, Zeravshan and
Gissar mountain ridges, mainly on their northern slopes. Total area of juniper
forests in Central Asia is about 600-650 thousand hectares, including 140-150
thousand hectares in Tajikistan. Average timber volume of Tajikistan’s juniper
forests is from 10 to 120 m3/ha. Bio-geographic isolation is certain
feature of Tajikistan’s juniper forests. On Turkestan mountain ridge the
Juniperus turkestanica (2300-3100 meters a.s.l.) is dominate. On
Zeravshan and Gissar mountain ridges the Juniperus seravschanica
(800-2000 meters a.s.l.) and Juniperus semiglobosa (1400-2500 meters
a.s.l.) are dominate. The highest productivity is observed in juniper forests
with tree density 0,4-0,6. At downturn, renewal process is rapidly reduced. In
view of specific biological features of junipers (slow growth, longevity) and
sever environmental conditions they are exist, changing of junipers by other
tree species practically does not happen. Immense juniper rootlets reliably
defend soil against washing out. In high dense juniper plantations the steady
grass cover is formed and it prevents any erosive processes. As junipers cover
abrupt and potentially mudflow risk slopes, they play important water
regulation, water security, soil protection and flooding preventing roles. Their
destruction results in landslides, mudflows and active erosive processes.
Juniper forests fall to the forests of 1-th category and subject to the strict
protection. Just sanitary cuttings are authorized here.
Xerophytic light forests mainly consists of dry resistant
leaf-fall tree formations with predominance of pistachio Pistacia vera,
almond Amygdalus bucharica, Punica granatum and other species of
Tajikistan’s flora. Main xerophytic light forests in Tajikistan are distributed
on the country’s south at elevation from 600 to 1700 meters above sea level. Xerophytic light forests in Tajikistan cover an area 80 thousand
hectares, while pistachio plantations contribute as much as 75% of all
xerophytic forests. Average tree density of stand pistachio forests in
Tajikistan is 0,3-0,5. Natural pistachio plantations have stage of life from 70
to 120 years old, artificial plantations from 30 to 60 years old. Average timber
volume of Tajikistan’s xerophytic light forests is 3-12 m3/ha and
natural increment about 0,3-1,2 m3/ha. Characteristic of pistachio
forests is rare tree position in contrast with entire rootlet combination.
Herbal cover consists of various ephemeral plant species. Pistachio forests are
the source of valuable fruits and timber. Average pistachio productivity in
Tajikistan makes 70-80 kg/ha, and in some areas exceed 300 kg/ha. Xerophytic
light forests, in particular pistachio forests, have enormous ecological, soil
protecting and mudflow preventing importance. Pistachio, almond and other fruits
are used for food and medicinal purposes. For these reasons forest cutting and
using of those trees for commercial purposes is forbidden. Just sanitary
cuttings are authorized here.
Saxaul trees mainly grow on the country’s south. Tree
plantations basically consist of white saxaul Haloxylon persicum and
black saxaul Haloxylon aphyllum. Largest saxaul forests in Central Asia
are in southern Kazakhstan (15 million hectares) and Turkmenistan (6 million
hectares). The area of saxaul forests in Tajikistan is about 10-12 thousand
hectares. Height of saxaul trees can reach 12 meters and age 100 years old.
Average tree density of saxaul forests in Tajikistan is 0,3-0,5, while natural
increment is about 0,3-1 m3/ha, depending on the local environmental
conditions. Saxaul forests play significant role in soil protection, sand
firmness and serve as local spring and autumn pastures. Clamping the huge masses
of sand and clay, saxaul trees protect oases, channels, roads and communications
from sand filling and raise pasture productivity.
Natural features of Tajikistan’s territory encourage pasturing development, but at once it is one of the most
essential pressures on the state of forest resources. More than 70% of total
area of the State Forest Reserves are in long-term use of agricultural
enterprises. Accordingly, forest authorities refused to provide effective
protection and reproduction of forest resources because of intensive pasturing
in many forested lands.
Forests in Tajikistan play important
water-security, erosion prevention, coast protection, sanitary-hygienic
functions as well as serve as habitats for many animals and plants. Rational
use of forest resources is a basis for sustainable development of the country .
However, as a result of intensive pressures, Tajikistan’s forests have undergone
to the essential changes for the last 70 years. In past time, before
industrialization and agricultural development, the area of former forests
exceeded today's area 2-3 times. According to the Tajik research expedition held
in 1932, the area of pistachio light forests was about 170 thousand hectares,
whereas now it does not exceed 80 thousand hectares. The reduction of both
forested area and tree density promoted to the development of natural disasters
in 1992-1999. Since 1970-s, Tajikistan’s forested area did not vary
significantly, though the average store of timber has been reducing and now it
is no more 70% compare to 1965. Artificial plantations contribute about 8% of
all forests.>more
