Decision 43 COM 8B.4
Hyrcanian Forests (Islamic Republic of Iran)

The World Heritage Committee,

  1. Having examined Documents WHC/19/43.COM/8B and WHC/19/43.COM/INF.8B2,
  2. Recalling Decision 30 COM 8B.24 adopted at its 30th session (Vilnius, 2006),
  3. Inscribes the Hyrcanian Forests, Islamic Republic of Iran, on the World Heritage List on the basis of criterion (ix);
  4. Adopts the following Statement of Outstanding Universal Value:

    Brief synthesis

    The Hyrcanian Forests form a green arc of forest, separated from the Caucasus to the west and from semi-desert areas to the east: a unique forested massif that extends from south-eastern Azerbaijan eastwards to the Golestan Province, in Iran. The Hyrcanian Forests World Heritage property is situated in Iran, within the Caspian Hyrcanian mixed forests ecoregion.  It stretches 850 km along the southern coast of the Caspian Sea and covers around 7 % of the remaining Hyrcanian forests in Iran.

    The property is a serial site with 15 component parts shared across three Provinces (Gilan, Mazandaran and Golestan) and represents examples of the various stages and features of Hyrcanian forest ecosystems. Most of the ecological characteristics which characterize the Caspian Hyrcanian mixed forests are represented in the property. A considerable part of the property is in inaccessible steep terrain. The property contains exceptional and ancient broad-leaved forests which were formerly much more extensive however, retreated during periods of glaciation and later expanded under milder climatic conditions. Due to this isolation, the property hosts many relict, endangered, and regionally and locally endemic species of flora, contributing to the high ecological value of the property and the Hyrcanian region in general.

    Criterion (ix): The property represents a remarkable series of sites conserving the natural forest ecosystems of the Hyrcanian Region. Its component parts contain exceptional broad-leaved forests with a history dating back 25 - 50 million years ago, when such forests covered most parts of the Northern Temperate region. These huge ancient forest areas retreated during Quaternary glaciations and later, during milder climate periods, expanded again from these refugia. The property covers most environmental features and ecological values of the Hyrcanian region and represents the most important and key environmental processes illustrating the genesis of those forests, including succession, evolution and speciation.

    The floristic biodiversity of the Hyrcanian region is remarkable at the global level with over 3,200 vascular plants documented. Due to its isolation, the property hosts many relict, endangered, and regionally and locally endemic plant species, contributing to the ecological significance of the property, and the Hyrcanian region in general. Approximately 280 taxa are endemic and sub-endemic for the Hyrcanian region and about 500 plant species are Iranian endemics.

    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, Semicollared Flycatcher and Caspian Tit. Some 58 mammal species have been recorded across the region, including the iconic Persian Leopard and the threatened Wild Goat.


    The component parts of the property are functionally linked through the shared evolutionary history of the Caspian Hyrcanian mixed forest ecoregion and most have good ecological connectivity through the almost continuous forest belt in the whole Hyrcanian forest region. Khoshk-e-Daran, is the only component that is isolated, however it still benefits from a high level of intactness and contributes to the overall value of the series. Each component part contributes distinctively to the property’s Outstanding Universal Value and the components together sustain the long-term viability of the key species and ecosystems represented across the Hyrcanian region, as well as the evolutionary processes which continue to shape these forests over time.

    Several component parts have suffered in the past from lack of legal protection, and continue to be negatively impacted to some extent by seasonal grazing and wood collection. The sustainable management of these uses is a critical issue for the long-term preservation of the site’s integrity and it will require strong ongoing attention by the State Party.

    Protection and management requirements

    All component parts of the property are state owned and strictly protected by national legislation. In the case of protected areas through the Nature Conservation Law and for areas outside of the protected areas by Iran’s Heritage Law. It will be important to align the boundaries of the existing protected areas to those of the property following inscription on the World Heritage List so as to harmonize and streamline the management and protection regime across the site as a whole.

    The management of the property’s components is under the responsibility of three national agencies, the Iranian Forests, Range, Watershed and Management Organization (FRWO), Department of Environment (DoE) and the Cultural Heritage, Handicrafts and Tourism Organization (ICHHTO). A National Steering Committee is in place to ensure coordination across the series as a whole. This mechanism will need to be maintained in order to guarantee comprehensive management of the site into the future, based on a common vision and supported by adequate funding. Each component part has a management plan however, a “Master Management Plan” for the whole property is also a long term requirement. The national and component specific plans should be maintained, developed and updated regularly together by the responsible management institutions, in cooperation with ministries, universities and NGOs.

    Public access and use of the area is legally regulated and logging, grazing, hunting and most other uses that may potentially impact the property are strictly prohibited within all component parts. Vehicle access and other uses and activities that may potentially impact the property are also either forbidden or strictly regulated. However, enforcement of access and use regulations is not always effective and requires strengthening. Particular attention is required to maintain and enhance where possible, ecological connectivity between components and to ensure effective regulation of seasonal grazing and wood collection.

  5. Takes note of the potential for this property to also meet criterion (x), and recommends the State Party to undertake significant further work to complete species inventories and confirm species composition and population conservation status within each of the components, and to consider submitting a re-nomination of the property if the further studies confirm the relevant values are sufficient to meet criterion (x);
  6. Requests the State Party to align the boundaries of the existing protected areas to those of the World Heritage property in the near future in order to harmonize and streamline the management and protection regime across the site as a whole;
  7. Also requests the State Party to adopt fully the Master Management Plan for the property as a whole by 2022, and to assure adequate funding is provided, and that comprehensive and detailed measures are in place to:
    1. Foster collaborative and participatory approaches to managing the property which respect rights, traditional practices and customs,
    2. Work collaboratively with local people to sustainably regulate grazing activities and seasonal/permanent settlements within all component parts, and minimize discernible negative impacts from grazing within the buffer zones,
    3. Develop a comprehensive plan on sustainable tourism for the property as a whole, especially in the Golestan National Park, including options to improve access as a means to develop ecologically sustainable tourism,
    4. Rationalize the forest road access system within all components to strictly limit vehicular access to site management activities, research and emergency responses;
  8. Further requests the State Party to prepare an Environmental Impact Assessment (EIA), consistent with the guidance of the IUCN Advice Note on World Heritage Environmental Assessment, on the proposed upgrading of the existing road in the Golestan National Park with a view to replacing the existing highway, and to provide a copy of this EIA for review by the World Heritage Centre and IUCN on completion, and prior to any decision to proceed with road upgrading;
  9. Encourages the States Parties of the Islamic Republic of Iran and the Republic of Azerbaijan to consider options for further serial and transboundary extension of the property to include other areas in Azerbaijan of internationally significant conservation value, taking into account Decision 30 COM 8B.24.
