Grassland ecosystems are biomes characterized by large expanses of grasses, herbs, and other non-woody plants, with few or no trees. These ecosystems are found on every continent except Antarctica and vary in size and diversity. Grasslands play a crucial role in maintaining biodiversity, supporting a wide range of plant and animal species. Grasslands are also important for carbon sequestration, water filtration, and soil conservation. They are highly productive ecosystems, supporting grazing animals like bison, antelope, and cattle. Grasslands are also home to a variety of birds, insects, and small mammals. However, grasslands are under threat from land conversion for agriculture, urban development, and overgrazing. Conservation efforts are focused on preserving and restoring grassland ecosystems to protect their important ecological functions and the species that depend on them. Research in the field of grassland ecosystems includes studying the effects of grazing, fire, climate change, and land management practices on ecosystem health and biodiversity.
