Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type.
Temperate Grasslands. Temperate prairies in the U.S. are lively with burrowing creatures such as prairie dogs and black footed ferrets, bison, deer, elk, pronghorns, coyotes, badgers and swift ...

[1] Steppes/shortgrass prairies are short grasslands that occur in semi-arid climates ...

A reflection of the planet’s increasingly volatile climate and the enduring influence of industrial interests, North American grasslands find themselves at the epicenter of one of the most ...
The Northern Tallgrass Prairie has a humid continental climate with moderate precipitation, usually between 450-700mm. Winters here are very cold, with a mean winter temperature of −12.5 °C (9.5 °F), and summers are warm, with a mean temperature of 16 °C (61 °F). The ecoregion's mean annual temperature is 2.5 °C (36 °F). [2]
Prairie dogs are named for their habitat and warning call, which sounds similar to a dog's bark. The name was in use at least as early as 1774. [5] The 1804 journals of the Lewis and Clark Expedition note that in September 1804, they "discovered a Village of an animal the French Call the Prairie Dog". [6]
