Ecoregions of Russia Russia spans an immense array of Eurasiaan biogeographic provinces, producing ecoregions that link the Barents Sea to the Bering Sea, the Caucasus to the Arctic Ocean, and the Pacific Ocean to the Ural Mountains. These landscapes underpin biodiversity associated with institutions and places such as the Kronotsky Nature Reserve, Siberian Federal University, Russian Academy of Sciences, Far East Federal University, and research programs tied to UNESCO and the IUCN. Historical expeditions like those of Vitus Bering, Semyon Dezhnev, Georg Wilhelm Steller, Nikolay Przhevalsky, and modern surveys by teams from Saint Petersburg State University and Lomonosov Moscow State University map patterns linking species distributions to paleoclimatic shifts recorded in archives such as the Pleistocene and events like the Last Glacial Maximum.

Overview

Russia’s ecoregions fall within major global realms recognized by organizations including the World Wildlife Fund and the Global Environment Facility, reflecting transitions among the Palearctic realm, the Arctic tundra belt, and the temperate zones associated with the Central Asian steppe. Key geographic anchors include the Ural Mountains, West Siberian Plain, Central Siberian Plateau, Yakutia (Sakha Republic), Kamchatka Peninsula, and the Caucasus Mountains, which interact with oceanic systems of the Arctic Ocean, Pacific Ocean, Black Sea, and the Sea of Okhotsk. Research institutions such as the Russian Geographical Society and initiatives like the Global Biodiversity Information Facility synthesize distributional data linking flagship taxa—Siberian tiger, Amur leopard, polar bear, Saiga antelope, European bison—to ecoregional boundaries.

Classification and Biogeographic Provinces

Russian ecoregions are organized into biomes and provinces used by the Commission for the Conservation of Antarctic Marine Living Resources frameworks adapted for northern latitudes, and informed by biogeographers from Zoological Museum of the Moscow State University and the Institute of Geography (Russian Academy of Sciences). Major provinces include the Arctic tundra province, the Boreal taiga province, the Temperate broadleaf and mixed forests province of European Russia and the Far East, the Steppe province of the Pontic–Caspian steppe, and the Montane province represented by the Caucasus and Altai Mountains. These provinces intersect with ecoregion schemes used in assessments by the Ramsar Convention and national policy instruments coordinated by the Ministry of Natural Resources and Environment (Russia).

Major Terrestrial Ecoregions

Terrestrial ecoregions include the Taimyr tundra, Yamal–Gydan lowland tundra, and the Chukchi Peninsula tundra in the far north, regions explored historically during voyages by Baron Eduard von Toll and later monitored by the Arctic and Antarctic Research Institute. Boreal ecoregions encompass the West Siberian taiga, East Siberian taiga, and the Sakhalin taiga, which host mammals recorded by collectors at the Zoological Museum of the Academy of Sciences and protected in reserves like Tigirek Nature Reserve. Temperate broadleaf ecoregions include the Sarmatic mixed forests of European Russia and the Amur mixed forests of the Russian Far East, where local projects by Russian Academy of Agricultural Sciences intersect with conservation of species such as the Amur tiger. Steppe ecoregions—Pontic steppe and Kazakh Steppe—are notable for grassland biodiversity and issues reported by the Convention on Biological Diversity and scholars at Novosibirsk State University. Montane ecoregions in the Caucasus and Altai harbor endemic flora documented by teams associated with Botanical Garden, Komarov Institute and fauna monitored in Golden Mountains of Altai UNESCO sites.

Freshwater and Marine Ecoregions

Freshwater systems include the Volga River basin, Ob River basin, Yenisei River basin, Lena River basin, and the freshwater ecoregions of Lake Baikal, a UNESCO World Heritage Site extensively studied by the Limnological Institute (Irkutsk), Russian Academy of Sciences, and international partners documenting endemic clades such as the omul (Coregonus autumnalis) and endemic amphipods. Marine ecoregions include the Barents Sea Shelf, White Sea, Sea of Azov, Black Sea, Baltic Sea (Russian coast), Sea of Okhotsk, Bering Sea and the productive Pacific salmon corridors utilized by fisheries managed through protocols involving the North Pacific Anadromous Fish Commission and fisheries institutes like the Russian Federal Fisheries Agency.

Threats and Conservation Status

Threats arise from extractive activities led by companies operating in regions overlapping with protected areas and indigenous lands represented by organizations communicating with forums such as the Arctic Council, BRICS environmental dialogues, and national regulators like the Federal Service for Supervision of Natural Resource Usage (Rosprirodnadzor). Drivers include oil and gas development in the Yamal Peninsula and Kara Sea, logging in the taiga affecting carbon budgets studied by Intergovernmental Panel on Climate Change contributors, agricultural conversion across the Volga and Southern Federal District, invasive species movements reported by Centre for Russian Nature Conservation, and climate-induced tundra thaw discussed at conferences at Lomonosov Moscow State University. Conservation response includes Russian federal reserves (zapovedniks) such as Wrangel Island Reserve, transboundary protected areas linked with Mongolia and China, and international designations via Ramsar Convention and UNESCO World Heritage listings.

Regional Case Studies and Notable Protected Areas

Case studies highlight Lake Baikal for freshwater endemism, Kronotsky Nature Reserve for volcanic and marine productivity, Putorana Plateau for intact plateaus with boreal endemics, Khingan–Amur–Lower Ussuri corridors for Amur tiger conservation coordinated with NGOs and agencies including WWF Russia, and Caucasus Nature Reserve for high endemism and interactions with Georgia and Azerbaijan biodiversity programs. Important protected areas include Beringia National Park, Magadan Nature Reserve, Stolby Nature Reserve, Bashkiria National Park, Zabaykalsky National Park, and others managed under legislation such as acts administered by the Ministry of Natural Resources and Environment (Russia) and monitored by research teams from Far Eastern Federal University and the Russian Academy of Sciences.
