Hyrcanian Forest

According to UNESCO, Hyrcanian Forest form a unique forested massif that stretches 850 km along the southern coast of the Caspian Sea. The history of these broad-leaved forests dates back 25 to 50 million years, when they covered most of this Northern Temperate region. These ancient forest areas retreated during the Quaternary glaciations and then expanded again as the climate became milder. Their floristic biodiversity is remarkable: 44% of the vascular plants known in Iran are found in the Hyrcanian region, which only covers 7% of the country. Hyrcanian Forest (also known as Caspian Forest), extends from the south of Azerbaijan to about 900 km to the east to the Iranian northern provinces of Gilan, Mazandaran and Golestan. This forest forms the outermost boundary of the west-Eurasian memorial deciduous forests to alpine thorn cushion corridors and forest-free dry vegetation of the Iranian highlands and Central Asia.

The Hyrcanian Forest cover the northern slope of the Alborz Mountain in Iran at the southern edge of the Caspian Sea and it contains very rich ecosystems due to the particular orographic and climatic situation. Hyrcanian forest contain the most important and significant natural habitats for conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science or conservation. It also contains superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance. It is outstanding examples in the record of significant on-going geological processes in the development of landforms and significant geomorphic or physiographic features. It is also outstanding example representing significant ongoing ecological and biological processes in the evolution and development of terrestrial, ecosystems and communities of plants.

To date, 180 species of birds typical of broad-leaved temperate forests and 58 mammal species have been recorded, including the iconic Persian Leopard. The ecosystems of the property support populations of many forest birds and mammals of the Hyrcanian region which are significant on national, regional and global scales. To date, 180 species of birds typical of broadleaved temperate forests have been recorded in the Hyrcanian region including Steppe Eagle, European Turtle Dove, Eastern Imperial Eagle, European Roller, Semi-collared Flycatcher and Caspian Tit. Some 58 mammal species have been recorded across the region, including the iconic Persian Leopard and the threatened Wild Goat.

Persian leopard

The Persian leopard is the last remaining Panthera species in Iran after the extinction of the Asiatic lion Panthera leo persica and the Caspian tiger Panthera tigris virgata. The leopard has therefore a unique importance for the ecological health of wide areas of natural ecosystems in the country and for the cultural heritage of Iran. The Persian leopard has been widely distributed in West, South and Central Asia since the times of the Pleistocene, but became extinct in some areas. Iran’s mountainous north is home to the greatest concentration of Persian leopards left on earth. Larger than their African cousins, Persian leopards once roamed far into the Caucasus Mountains in central Asia, including parts of Armenia, Azerbaijan and Georgia. Now, only scattered populations of these big cats remain in those countries, often in isolated patches far removed from others of their kind. Iran is leopards’ best chance for survival. Expanding villages, encroaching livestock and busy highways destroy habitat and create hazards for such a wide-ranging predator. In recent years, a new indirect threat has emerged as well: economic sanctions.

 Although Iran has an impressive number of parks and protected areas, herders sometimes graze their livestock in prohibited zones. When leopards occasionally kill vulnerable cows or sheep, the herders poison the carcasses to get rid of the offending predator. Cubs are born with their eyes closed, eventually opening after 4-5 days. Their fur is thicker than that of adult Persian leopards. Weaning occurs at 3 months, by which time they start following their mothers on hunting trips. They make it out of their juvenile year only around 50% of the time, as out of a litter of four, only two reach adulthood. Being obligate carnivores, they eat ungulates like roe deer, goitered gazelle, West Caucasian tur, mouflon, wild boar, and onager. However, they can adapt to changes in their diet, depending on food availability. They spend a solitary life, except during the mating season and when a female is raising her cubs. Individuals have well-pronounced territories marked by ground scraping, tree scratching, and urine spraying. These leopards roar and growl threateningly, a trait that they share with tigers, lions and jaguars. It is because a part of their voice box, is actually replaced with a ligament, enabling them to stretch it to have a bigger sound passage, resulting in a wider pitch range.
