The southern region of the dry puna encompasses an even drier puna known as the desert puna. In the desert puna the average rainfall ranges from only 51–406 mm. The desert puna is dominated by the huge salt lakes and is known for the scattered halophytes around and in the depressions. [3] These salt lakes are home to the endemic Andean flamingo.
The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Tropical grasslands are mainly found between 5 degrees and 20 degrees in both North and south of the Equator. [2]
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.
The grass grows from a large rhizome that anchors it into shifting and unstable sands. When there are many plants on a dune, their rhizomes form a network that helps to stabilize it, preventing erosion. The network becomes "the skeleton of the foredune." [6] This makes the grass a valuable species for landscape rehabilitation in native beach ...
The rainfall level for that grassland type is between 90 and 150 centimeters per year. Grasses and scattered trees are common for that ecoregion, as well as large mammals, such as wildebeest (Connochaetes taurinus) and zebra (Equus zebra). Notable tropical and subtropical grasslands include the Llanos grasslands of South America. [57]
Most of this ecoregion is occupied by farms and ranches, and cattle grazing has affected 75% of the Western short grasslands, particularly the southern portion. This overgrazing has led to an invasion of desert scrub plants from the southwest, such as mesquite. Despite this, 40% of the ecoregion is considered to be intact.

St. Augustine is a dark green grass with broad, flat blades. It spreads by aboveground stolons, commonly known as "runners", and forms a dense layer. The grass occurs on both sides of the Atlantic Ocean, [1] including much of the southeastern United States, Texas, [2] [3] Mexico, and Central and South America. [1]
