Prairies

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 Russia and Central Asia.

The Western Gulf coastal grasslands are a subtropical grassland ecoregion of the southern United States and northeastern Mexico. It is known in Texas as "Coastal Prairie". The ecoregion covers an area of 77425 km2, extending along the shore of the Gulf of Mexico from southeastern Louisiana through Texas and into the Mexican state of Tamaulipas, where it is known as the Tamaulipan pastizal. Less than 1% of the ecoregion remains in pristine condition, almost entirely in Texas.
