How did ranchers' use of land contribute to the decline of the cattle kingdom?

Ranchers' intensive use of land for cattle grazing led to overgrazing, which degraded pastures and diminished the land's productivity. Additionally, the expansion of barbed wire Fencing restricted open range access, creating conflicts over land use and limiting cattle movement. The combination of these factors, along with severe droughts and the rise of agriculture in the Great Plains, contributed to the decline of the cattle kingdom by making large-scale cattle ranching less sustainable.
