In physical geography, tundra is a type of biome where the tree growth is hindered by low. In tundra, the vegetation is composed of dwarf shrubs, sedges and grasses.
In physical geography, a steppe is an ecoregion, in the montane grasslands and shrublands. Precipitation level alone is not what defines a steppe climate; potential evapotranspiration a similar association of plants that can be found in the driest areas with a Mediterranean-like climate; it usually has a short wet period.
