What has replaced the wild grass bison and pronghorn in the Great Plains?

In the Great Plains, the wild grasslands that once supported bison and pronghorn have often been replaced by agricultural development, including cropland and pasture for livestock. This transformation has led to habitat loss and fragmentation, impacting native species and altering the ecosystem. In some areas, invasive plant species have also taken hold, further displacing the native grasses that supported these animals. As a result, the biodiversity of the region has been significantly diminished.
