Answer:
In the US and Canada, as well as Australia and New Zealand, cattle ranching is a extensive grazing operation where cattle are set to graze in native grassland or some forested areas. Using cattle on rangelands is a way to manage and maintain the growth of native plants through different grazing practices. This way, sustainability and conservation of native prairie and plains and forests are practiced on private rangeland, allowing native vegatation and wildlife to thrive and maintain a natural ecosystem. At the same time, you are gaining a profit from the cattle you run on your ranch by selling cull cows and calves at weaning time.
