Temperate grasslands, savannas, and shrublands are terrestrial biomes defined by the World Wide Fund for Nature. [1] The predominant vegetation in these biomes consists of grass and/or shrubs. The climate is temperate and ranges from semi-arid to semi-humid. The habitat type differs from tropical grasslands in the annual temperature regime and ...
Flowering big bluestem, a characteristic tallgrass prairie plant. The tallgrass prairie is an ecosystem native to central North America.Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination.
Grassland existing as a result of human activity (mowing or livestock grazing), where environmental conditions and the species pool are maintained by natural processes. [6] They can also be described as the following: "Semi-natural grasslands are one of the world's most biodiverse habitats on a small spatial scales." [7]
Prairies are considered part of the temperate grasslands, savannas and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, and the steppes of Eurasia.
In a temperate grassland, grasses and other plants are the primary producers at the bottom of the pyramid. Then come the primary consumers, such as grasshoppers, voles and bison, followed by the secondary consumers, shrews, hawks and small cats. Finally the tertiary consumers, large cats and wolves.
The mean annual rainfall ranges from 280–600 mm (11–24 in) across the community with a rainfall peak in winter. The distribution of the Iron-grass Natural Temperate Grassland is located within various Aboriginal Nations, including lands of the Ngarrindjeri, Peramangk, Kaurna, Narrunga, Nukunu and Ngadjuri people.

The Eastern Temperate Forests is a Level I ecoregion of North America designated by the Commission for Environmental Cooperation (CEC) in its North American Environmental Atlas. The region covers much of the Eastern and Midwestern United States , the U.S. Interior Highlands , and parts of Ontario , Quebec , and the Maritimes .
