Hyrcanian Forests (Caspian)
A 50-million-year-old living relict: ancient broadleaf forest riding the Caspian's wall of cloud.
8 highlights · tap a pinThe Hyrcanian (Caspian) Forests are a continuous belt of ancient temperate broadleaf and mixed forest running roughly 850-1,000 km along the southern shore of the Caspian Sea, climbing the northern slopes of the Alborz from sea level to the high ridgelines. These are biological relicts of the Arcto-Tertiary forests that once blanketed much of the Northern Hemisphere 25-50 million years ago, surviving the Quaternary ice ages thanks to the Caspian's moderating moisture. Inscribed by UNESCO as a natural World Heritage Site in 2019, the forest harbors endemic and relict trees such as Persian ironwood (Parrotia persica), Caspian zelkova and Caucasian wingnut, plus flagship wildlife like the Persian leopard and brown bear. For visitors the experience ranges from the cloud-drowned ridges of Abr and Alimestan to the deep wildlife reserve of Golestan National Park.
