Grasslands, also known as prairies or savannas, are ecosystems dominated by grasses and other herbaceous plants, with few or no trees. They can be found on every continent except Antarctica and are typically located in the interiors of continents, away from the moderating influence of large bodies of water.
There are two main types of grasslands: tropical and temperate.
Grasslands are characterized by a semi-arid climate, with low to moderate rainfall and periodic droughts. The temperature range can be quite extreme, with hot summers and cold winters.
Grasslands typically have deep, fertile soils that are well-suited for the growth of grasses. The roots of the grasses help to hold the soil in place, preventing erosion.
Plants in grasslands have adaptations to survive the frequent fires that occur in these ecosystems, such as deep roots that can regrow after a fire. Animals in grasslands have also evolved adaptations to the open landscape, including speed and agility to escape predators.
Grasslands around the world are being threatened by human activities such as agriculture, urbanization, and the introduction of non-native species. Conservation efforts are important to protect the biodiversity of these ecosystems.
Key concepts to understand about grasslands include:
