East European forest steppe
The East European forest steppe ecoregion (WWF ID: PA0419) is a patchwork of broadleaf forest stands and grasslands (steppe) that stretches 2,100 km across Eastern Europe from the Ural Mountains in Ural, through Povolzhye, Central Russia to the middle of Ukraine. There are isolated areas of similar character off the western end in eastern Romania, Moldova, and Bulgaria.
The region forms a transition zone between the temperate forests to the north, and the steppe to the south. The forest-steppe is an area of Russia in which precipitation and evaporation are approximately equal. The ecoregion is in the Palearctic realm, with a Humid Continental climate. According to one definition of its boundaries, it covers 727,269 km2 (280,800 sq mi).
The ecoregion forms a long band, about 2,100 km long and 600 km wide, from the western edge of Siberia at the Ural Mountains in Ural in the east, through Povolzhye, to Central Russia and Ukraine. Most of the terrain is rolling hills and some plains. Average elevations range from 150 meters (above sea level) in the lowlands to 250 meters in the hills, with some isolated ranges of low mountains on the edges of the area.
The ecoregion can be divided into sub-provinces from west to east: Dnieper Upland, Dnieper Lowland, Central Russian Upland, Oka–Don Plain, Volga Upland, and the Trans-Volga. Moisture diminishes as the ecoregion stretches to the east, as does the forest fragmentation.
The climate in most of the ecoregion is Humid continental climate, warm summer (Köppen climate classification (Dfb)). This climate has large seasonal temperature differentials. It has a warm summer, with at least four months averaging over 10 °C (50 °F), but no month averaging over 22 °C (72 °F). Seasonal temperature extremities increase eastward across the ecoregion, due to the nature of continental climate towards the center of the continent.
The natural vegetation of the forest steppe is a mosaic of woodlands and open shrublands and grasslands.
Shrublands typically include the shrubs Caragana frutex, Prunus fruticosa, and Prunus stepposa. Stipa ucrainica, and Bromus riparius are common grasses.
Typical trees of the woodlands and forests include Quercus robur, Tilia cordata, Acer platanoides, Juniperus communis, Quercus petraea, Picea abies, Abies alba, Alnus glutinosa, Fagus sylvatica, Taxus baccata, Acer pseudoplatanus, Malus sylvestris, Viburnum lantana, Fraxinus excelsior, Aesculus hippocastanum, Rhamnus cathartica, Ulmus glabra, Ulmus minor, Populus alba, Pinus sylvestris, Betula pendula, Populus tremula, Populus nigra, Salix alba, Juglans regia, and Corylus avellana.
