It stretches through Hungary , Bulgaria , Romania , Moldova , Ukraine , southern Russia , Kazakhstan , Xinjiang , Mongolia and Manchuria , with one major exclave , the Pannonian ...
It is the transition ecoregion from the Great Plains prairie and steppe temperate grasslands in the south to the Taiga biome forests in the north. In central Asia the forest steppe ecotone is found in ecoregions in the mountains of the Iranian Plateau , in Iran , Afghanistan , and Balochistan .
The Alpine-steppe is a high altitude natural alpine grassland, which is a part of the Montane grasslands and shrublands biome. Alpine-steppes are unique ecosystems found throughout the world, especially in Asia , where they make up 38.9% of the total Tibetan plateau grassland's area.
At higher elevations on the plateau, different types of steppe vegetation dominate depending on soil conditions, for example in the slopes and foothills of the Atlas Mountains there is a steppe dominated by Stipa tenacissima whereas Artemisia herba-alba dominates in where there are silty slopes and depressions; Lygeum spartum steppe grows in ...
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.
The dominant vegetation of this ecoregion is sagebrush (Artemisia tridentata), often associated with various Agropyron species or fescue grass.At its upper altitudinal limit, the shrub steppe grades into the bordering mountain ecoregions, namely the South Central Rockies forests, the Colorado Rockies forests and the Wasatch and Uinta montane forests.
The North Saharan steppe and woodlands is a desert ecoregion, in the deserts and xeric shrublands biome, that forms the northern edge of the Sahara.It extends east and west across Northern Africa, south of the Mediterranean dry woodlands and steppe ecoregion of the Maghreb and Cyrenaica, which is part of the Mediterranean forests, woodlands, and scrub biome.
