Tallgrass prairies are a type of grassland ecosystem characterized by tall grasses and few trees. They are primarily found in the central United States, particularly in states like Kansas, Nebraska, and Iowa. These prairies support a diverse range of plant and animal species, including wildflowers, birds, and mammals such as bison. Historically, tallgrass prairies covered millions of acres, but much of this land has been converted for agriculture. Today, only a small percentage remains intact, making conservation efforts crucial. Organizations work to protect these ecosystems, recognizing their importance for biodiversity and soil health.
