Why were some pieces of land more coveted than others? life on the plains

When horses arrived on the Plains along with the Spanish colonizers, or conquistadores, they disrupted agricultural norms and intensified hunting competition between Native American groups.

The Plains were very sparsely populated until about 1100 CE, when Native American groups including Pawnees, Mandans, Omahas, Wichitas, Cheyennes and other groups started to inhabit the area. The climate supported limited farming closer to the major waterways, but ultimately became most fruitful for hunting large and small game.
