The vast grasslands that once covered the heart of North America have largely disappeared beneath the plow, making the remaining prairie fragments precious sanctuaries for wildlife that have evolved over millennia in these expansive ecosystems. These protected havens preserve not just rare plants and animals, but entire ecological communities that demonstrate how the Great Plains functioned before European settlement transformed the landscape. The surviving prairies support an astonishing diversity of species, from tiny native bees to massive bison herds, all adapted to life in the wind-swept grasslands.
Visiting these wildlife refuges and preserves offers opportunities to witness authentic prairie ecosystems while observing species that have become increasingly rare as their habitat shrinks. Here is a list of 20 prairie wildlife havens across the Great Plains where visitors can experience the natural heritage of America’s grassland region.
