On large fields there are likely sites heavily, moderately, or lightly grazed - and even ungrazed. This creates a wide range of homes for a great variety of species. Some birds and animals like small overgrazed sites. Good examples of this are the burrowing owl and most birds of prey. These birds like to be able to see around them.
Antelope also appreciate the sage that comes in on overgrazed areas.
Birds such as the western meadowlark and long billed curlew, and ruffed grouse benefit from modern grazing, as do deer. Deer are attracted to patches of grazed grass in early sprung, a time when they require a higher level of forage nutrition. Waterfowl, sage grouse, sharp-tailed grouse and some of the smaller sparrows prefer light grazing regimes. It is believed that moose do best in situations where no livestock grazing occurs. Today, cattle do not compete with any native prairie ungulate species to any great extent.
