Grasslands can grade into savannas where rainfall is sufficient to support woody shrubs or trees, or they grade into deserts where rainfall is insufficient to support extensive plant life. The two types of temperate grasslands are steppes and prairies. The three most important features of temperate grasslands are their climate, soil and flora and fauna. Lupines are mostly found in habitats or grassland areas where they can be a dominant species living among many other types of plant life.

The dust retention content was determined by an electronic analytical balance and a . Many grasses are also specially adapted to handle heat and droughts without much water. Tropical grasslands also have very large grazing and herd animals, like elephants, antelope and wildebeasts. Changes to precipitation pattern have also been increasing globally. With all this beauty, it also a strong plant, that can stand severe cold by going dormant.
