North American ranching did not evolve as a solution to the ecological contradictions of pastoralism. This has been the conventional view from an institutional perspective, but from a perspective of interspecies relations, the reverse is more plausible. Rather than invest in careful husbandry, early colonists released livestock to fend for themselves and henceforth partook in the eradication of predators. This estrangement of livestock from the domestic sphere and the persecution of predators have lasted beyond the open range era and persist on private ranches. Range science tailored its prescriptions to the free-roaming livestock practices of ranching. But stocking rate guidelines are not sufficient to prevent the degradation of rangelands. Trophic cascade ecology has since demonstrated that the sound distribution of grazing activities takes place on a landscape of fear where nonlethal predation effects prevent the overutilization of key sites. In order to replicate these effects without undue losses, now that predators are protected, ranchers are compelled to reformulate their interspecies relations of estrangement and persecution. Technologies are a poor substitute for human presence, and ranchers are faced with adopting pastoralist practices of herding in order to improve rangelands and maintain surveillance to prevent predation. Thus by turning to pastoralist interspecies relations and practices, ranching might resolve its ecological contradictions.
