Located in northern Iran along the Caspian Sea coast, the Hyrcanian Forests represent a unique temperate forest ecosystem that has persisted for millions of years. This natural site encompasses dense, lush woodlands characterized by a diverse canopy structure with multiple layers of vegetation, evergreen and deciduous trees, and a rich understory of shrubs and herbaceous plants. The forests occupy a narrow band of mountainous terrain between the sea and the Alborz Mountains, creating a distinctive microclimate shaped by proximity to the Caspian waters. The site's ecological significance stems from its exceptional biodiversity, including numerous endemic plant and animal species found nowhere else on Earth, and its role as a refuge for species that have survived since ancient geological periods. The Hyrcanian Forests are notable for their pristine condition in many areas, maintaining ecological processes that have operated largely unchanged for millennia. This exceptional natural heritage justifies recognition as a site of outstanding universal value for the conservation of a relict forest ecosystem of global importance.
