In 1993, a few bison were introduced to America's dying grasslands. Now, thousands of those beasts, once hunted to near extinction, are helping bring the prairie ecosystem back to life

Oklahoma's Tallgrass Prairie Preserve is restoring bison populations and their habitat. Bison grazing and wallowing create favorable conditions for diverse plant and animal life. Controlled burns also remain essential for prairie recovery and renewal. These efforts help rebuild ecological relationships within the ecosystem. The preserve demonstrates successful species restoration alongside modern land use.
