Bison and Prairie Ecosystem Management

The video explores the restoration of the Tall Grass Prairie in Oklahoma, focusing on the reintroduction of bison and the use of fire to maintain the ecosystem. Historically, the prairie was a vast grassland home to millions of bison, but European settlement led to its decline. Today, efforts by the Nature Conservancy have restored a significant portion of the prairie, using bison as natural grazers and controlled burns to mimic historical fire patterns. The video highlights the ecological importance of these practices and suggests that similar methods could be applied globally to restore damaged grasslands.
