Wet prairies may form in low-lying areas with poor drainage; dry prairie can be found on uplands or slopes. Dry prairie is the dominant habitat type in the Southern Canadian agricultural and climatic region which is known as Palliser's Triangle. It was once thought to be completely unarable, but is now one of the most important agricultural ...
The habitat type is known as prairie in North America, pampas in South America, veld in Southern Africa and steppe in Asia. Generally speaking, these regions are devoid of trees, except for riparian or gallery forests associated with streams and rivers. [1] Steppes/shortgrass prairies are short grasslands that occur in semi-arid climates ...
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.

The shortgrass prairie is an ecosystem located in the Great Plains of North America.The two most dominant grasses in the shortgrass prairie are blue grama (Bouteloua gracilis) and buffalograss (Bouteloua dactyloides), the two less dominant grasses in the prairie are greasegrass (Tridens flavus) and sideoats grama (Bouteloua curtipendula).
The Texas Blackland Prairies are a temperate grassland ecoregion located in Texas that runs roughly 300 miles (480 km) from the Red River in North Texas to San Antonio in the south. The prairie was named after its rich, dark soil. [3] Less than 1% of the original Blackland prairie vegetation remains, scattered across Texas in parcels. [4]
