Knowra East Siberian taiga East Siberian taiga A vast boreal forest region of eastern Siberia, shaped by severe continental climates and permafrost. Its forests are dominated by deciduous larches adapted to extreme cold.
Permafrost : Ground that remains at or below 0 °C for at least two consecutive years. Permafrost restricts drainage and roots, shaping the region’s soils and vegetation.
Active layer : The surface ground layer above permafrost that thaws during the warm season and refreezes in winter. Its seasonal depth controls rooting space and the movement of meltwater.
Boreal forest carbon cycle : The exchanges and storage of carbon among boreal forests, soils, and the atmosphere. Larch forests and frozen soils store carbon whose balance can shift with warming and fire.
Central Siberian taiga : The boreal forest region of central Siberia, west of the East Siberian taiga. Its position to the west helps distinguish adjacent Siberian taiga regions.
Siberian larch : A deciduous conifer native to Siberia that sheds its needles each autumn. Its cold tolerance and deciduous habit make it the region’s characteristic tree.
Wildfire in Siberia : Vegetation fires occurring across Siberian forests and other ecosystems. Fire periodically removes forest cover and creates conditions for larch regeneration.
Arctic amplification : The phenomenon in which the Arctic warms faster than the global average. Rapid northern warming alters permafrost, fire regimes, and forest boundaries in Siberia.
Far Eastern taiga : The boreal and temperate forests of Russia’s Far East, influenced by Pacific climates. Stronger maritime and monsoon influences distinguish the Far East from the colder continental interior.
Subarctic climate : A climate with long, very cold winters and short, cool summers, commonly found at high northern latitudes. This broad climate category captures the region’s short growing season and severe winters.
Larch forest : A forest dominated by larch trees, which lose their needles in winter. This forest type is the characteristic vegetation across much of eastern Siberia.
