Forests of Iran

Last updated November 16, 2024

Iran's forests are part of Iran's natural resources. Most of the country's forests are located in the northern regions, on the southern shores of the Caspian Sea. These forests have a temperate humid climate and are extended from the east of Ardabil province to North Khorasan province.^[1]^{[ clarification needed ]} They also spread and cover the three provinces of Gilan, Mazandaran, and Golestan. The Alborz mountain range, which is the highest mountain range in the Middle East, stands like a wall against the moisture of the Caspian Sea and prevents the moisture coming into the central regions of Iran; therefore, these clouds are forced to rain in the northern areas of the country leaving the central areas dry and barren.^[2]

There are 3.4 million hectares (13,000 sq mi) of forests on the northern slopes of the Alborz Mountains and the coastal provinces of the Caspian Sea. Other parts of the country have forests up to 3 million hectares (12,000 sq mi). Of these forests, only 1.3 million hectares (5,000 sq mi) can be used for industrial exploitation, the rest of the forests are not exploited due to lack of proper maintenance or natural damage. According to the records, Iran had many and varied forests from ancient times to the beginning of the eighteenth century. During the Achaemenid period, the expanse of forests in Iran with the current borders reached more than 16 million hectares (62,000 sq mi). Deforestation in Iran began after the Mongol invasion and reached its highest point in the last three centuries. During the Qajar dynasty, about 130,000 t (130,000 long tons; 140,000 short tons) of charcoal were produced and exported abroad by cutting down the forest trees.^[3]

Nationalization of forests and fields

The government’s program included the nationalization of the forests, fields, waters, and natural resources.

On January 26, 1963, forests were declared national according to the framework of the White Revolution. In accordance with the second principle of the White Revolution, about 120 million hectares (460,000 sq mi) of forests and fields which were also known as green gold mines, were given to the government for national exploitation.^[3]

Trees and soil erosion

Trees, shrubs, and vegetation in general have an effective role in maintaining the stability of the soil and increasing their permeability. The surface soil that can be used by humans is not more than a few centimetres, so its preservation is vital. In barren areas, wind erosion is the main cause of soil degradation and in windy areas, trees are an effective factor in soil stabilization.^[4]^[5] In dry areas, wind erosion has been the main cause of soil degradation, and in windy areas, trees are considered to be a factor in soil stabilization.^[6]

Warning About the Destruction of Iran's Forests

According to government statistics, over 1.5 million square metres (16×10^⁶ sq ft) of wood were harvested from the forests of northern Iran during the years 2010 and 2011. The head of the Forestry Association reported that this figure represents the official data in this area, and, without a doubt, illegal logging has also been occurring alongside these legal extractions, contributing further to the overall forest loss. Forest specialists have stated that the northern forests of Iran have suffered such damage that they cannot withstand this extensive level of logging. It is predicted that, if this trend continues, the forests of northern Iran will face the same fate as the forests in the west of the country and will be eradicated. Currently, biodiversity and wildlife in the northern forests have already been significantly reduced. Additionally, experts have identified the destruction of vegetation cover and tree cutting in the region as one of the causes of devastating floods in northern Iran.^[7]

The head of Iran's Environmental Protection Organization has also stated that over the past five decades, Iran's forested area has decreased from 18 million hectares (69,000 sq mi) to 14 million hectares (54,000 sq mi). The deforested land has subsequently turned into desert.^[8]

It is estimated that 63,000 hectares (240 sq mi) of the Zagros and northern forests of Iran are destroyed annually, driven by human greed rather than necessity.^[9]

The Food and Agriculture Organization (FAO) has reported that Iran is one of 70 developing countries worldwide with limited forest cover, and this scarce forest cover is being destroyed at a faster rate than in other regions globally.^[10]

The climate in the forests

Some forests (for example, evergreen forests) are less affected by climate change; But others (for example, temperate deciduous forests) are severely affected, losing all their leaves each fall.

The growth of the trees in the forests depends on several factors, mainly sunlight, type of soil and water, temperature, and the genetic potential of trees. Most of these factors are directly or indirectly related to the weather^[11]

In summer, the temperature inside the forest is usually between 6–8 °F (−14 – −13 °C) lower than the temperature outside the forest, but in winter the temperature in the forest is very close to the outdoor temperature and sometimes a few degrees warmer. The outdoor soil temperature on a summer day may reach to 90 °F (32 °C), while soil temperature in a nearby forest lines to 20 °F (−7 °C).

During winter, in a coniferous forest, because of insulation such as sunshade and litter on the forest floor, the forest soil freezes and in spring, the soil warms up.

Forest regions of Iran

Iran's forests can be divided into five vegetation regions:

1. Hyrcanian region (Caspian) which forms the green belt of the north side of the country.

2. The region of Iran and Turan, which are mainly scattered in the center of Iran.

3. Zagros region, which mainly contains oak forests in the west of the country.

4. The Persian Gulf region, which is scattered in the southern coastal belt.

5. Arasbarani region, which contains rare and unique species.

Iran’s forests are classified in five regions and the country ranks 45th among 56 countries with forests in the world.^[12]

Caspian Sea Region

The forests in the north part of the country, which are known as the forests of the Hyrcanian or Caspian vegetation zone, wet forests, and industrial forests of the north, such as the green strip of the southern Caspian Sea and the northern profile of the Alborz mountain range from Astara to Glidaghi, approximately 800 km (500 mi) long, 20 to 70 km (12 to 43 mi) wide, and an altitude of 2,800 metres (9,200 ft) meters above sea level.

So far, 80 species of trees (mainly broadleaf), four species of native conifers, and 50 species of shrubs have been identified in these forests, most of which are mixed species of beech, hornbeam, oak, maple, and alder.

These forests are remnants of the third geological period. But the reason for the scarcity of conifers in the Hyrcanian forests is the lack of progress and expansion of glaciers in the late third and early fourth geological period in these areas.

This area in the north is the green belt of the country in Gilan, Mazandaran, and Golestan. The Hyrcanian region has a humid climate and is affected by the Caspian Sea.

<span class="mw-page-title-main">Elburz Range forest steppe</span> Region of Iran and Azerbaijan

The Elburz Range forest steppe ecoregion is an arid, mountainous 1,000-kilometer arc south of the Caspian Sea, stretching across northern Iran from the Azerbaijan border to near the Turkmenistan border. It covers 63,300 square kilometres (24,400 sq mi) and encompasses the southern and eastern slopes of the Alborz Mountains as well as their summits. The Caspian Hyrcanian mixed forests ecoregion's lush green mountainsides and plains receive moisture from the Caspian Sea from this ecoregion's northern border. The vast Central Persian desert basins ecoregion forms its southern border.

The Hyrcanian forests are a zone of lush lowland and montane forests covering about 55,000 square kilometres (21,000 sq mi) near the shores of the Caspian Sea in Iran and Azerbaijan. The forest is named after the ancient region of Hyrcania. The World Wide Fund for Nature refers to the ecoregion as the Caspian Hyrcanian mixed forests. Since 5 July 2019, the Hyrcanian Forests have been designated a UNESCO World Heritage Site. In September 2023, the heritage site expanded to incorporate portions of the forest located in Azerbaijan.

The Alborz range, also spelled as Alburz, Elburz or Elborz, is a mountain range in northern Iran that stretches from the border of Azerbaijan along the western and entire southern coast of the Caspian Sea and finally runs northeast and merges into the smaller Aladagh Mountains and borders in the northeast on the parallel mountain ridge Kopet Dag in the northern parts of Khorasan. All these mountains are part of the much larger Alpide belt. The Alborz range is divided into the Western, Central, and Eastern Alborz Mountains. The Western Alborz Range runs south-southeastward almost along the western coast of the Caspian Sea. The Central Alborz runs from west to east along the entire southern coast of the Caspian Sea, while the Eastern Alborz Range runs in a northeasterly direction, toward the northern parts of the Khorasan region, southeast of the Caspian Sea. Mount Damavand, the highest mountain in Iran measuring 5,610.0 m, is located in the Central Alborz Mountains. Mount Damavand is the 12th most prominent peak in the world and the second most prominent in Asia after Mount Everest.

Havar is a village in Almeh Rural District, Samalqan District, Maneh and Samalqan County, North Khorasan Province, Iran. At the 2006 census, its population was 228 inhabitants, distributed amongst 56 families. Havar is noteworthy for marking the Easternmost extremity of the highly biodiverse Caspian Hyrcanian mixed forests – most of which are to be found fringing the Caspian Sea. The spur – almost 'Island' – of forest which Havar shares with the villages of Jowzak, Darkesh and Kashanak owes its extension into the more arid regions to the East of the Caspian sea to the trapping of moisture from that sea by the Aladagh Mountains, which form an extension, of lower altitude, of the Alborz mountains to the West. This forested area lies within the Khorasani Kurdish region of Northeastern Iran and Southwestern Turkmenistan. The only settlement of any size close to Havar and its neighbouring villages is Bojnord the capital of North Khorasan Province.

Alamut or Rudbar is a region in Iran including western and eastern parts on the western edge of the Alborz (Elburz) range, between the dry and barren plain of Qazvin in the south and the densely forested slopes of the Mazandaran province in the north. Starting from Qazvin toward Alamut, passing through the first range of hills, curvatures, forms, are significant themes in nature's composition of this area. The famous Ismaili castle of Alamut and numerous others are in this area, which served as the heartland of the state founded by Hassan-i Sabbah.

The total forest area of Azerbaijan is 1,021,880 ha or 11.8% of the country's area. The forest biomes consist of temperate deciduous forests, temperate broadleaf and mixed forests, temperate coniferous forests and riparian forests. Specialists estimate that in the 8th-9th centuries the forest cover was around 30-35%, most of it situated in mountainous areas.

The wildlife of Turkmenistan is the flora and fauna of Turkmenistan, and the natural habitats in which they live. Turkmenistan is a country in Central Asia to the east of the Caspian Sea. Two thirds of the country is hot dry plains and desert, and the rest is more mountainous. Very little rain falls in summer and the chief precipitation occurs in the southern part of the country in the winter and spring. The Caspian coast has milder winters.

The Kopet Dag semi-desert ecoregion is a small ecoregion that crosses the border of southwestern Turkmenistan into northeastern Iran. It covers a transition zone between the deserts to the north and west, and the foothill steppes and woodlands in the higher Kopet Dag mountains to the east and the Alborz Mountains to the south. The terrain is mostly barren semi-desert and widespread 'takir', a type of seasonal salt flat or dried clay deposit in an interdune depression.

Miqan Wetland is a wetland located in Markazi province, Iran. In years with good rainfall, the wetland has significant water level and in the years with less rain, the surface of the wetland generally dries and becomes a desert. The height of the wetland is 1,700 meters (5,600 ft) above sea level and the water inside of it varies in different seasons. Miqan is supplied from different water sources such as rainfall, water of three rivers known as Qarah Kahriz (Koohrood) River, Farahan River, Shahrab River, and Arak's wastewater treatment sewage. The area of the wetland is about 25,000 hectares (97 sq mi), which includes a lake with three islands in the middle and the surrounding plains. Archaeologically, the wetland's formation dates back to the Paleocene, which was due to the movement of the surrounding tectonic plates of the earth.

Tatoid dilalects are dialects of the Tati language spoken in the Iranian provinces of Gilan, Qazvin and Alborz. Tatoid two Tati like ofshoots: Rudbari, Taleghani and Alamuti. Tatoid includes the Rudbari, Taleghani and Alamuti dialects. According to Stilo, this special status for this recent type is that these two varieties were originally Tatic which, under the intense influences of Caspian and Persian, have lost all their Tatic grammatical structures.

The Clouds Forest is located on the slopes of the Alborz Mountains in Iran. It includes a sea of clouds that pass through it throughout the year. The forest encompasses an area of 530,000 hectares, extending from Semnan Province to Golestan Province in the north. It constitutes one of the most impressive areas of Shahroud city in Semnan Province, situated east of Tehran's capital. This forest represents a significant remnant of the ancient Hyrcanian forests during the Tertiary period. It extends along the southern shores of the Caspian Sea in the form of a verdant band across Semnan Province.
