sherpa, cattle and elk have close to the same diet on an annual basis, with cattle utilizing more of the grasses in the winter than elk.
on an average elk use 64% grass, 20% browse, and 16% forbs on annual basis. cattle use 81% grass, 12% forbs and 7% browse. we don't go to the mountains until well after the elk have moved through with their newborn calves and went to the alpine meadows where they summer. we are out of there before they move back down in the late fall
we use proper range management practices that benefit all wildlife along with the regulated numbers we put on open range.
"open range" is a misleading term where i live. because of land grants given before washington became a state, our land is a checkerboard of private, railroad, federal and state land. typically every other section is owned by a different entity.
i write checks to three family's, burlington northern railroad, boise cascade lumber co., and the federal gov't. for the graze i use. i also own 14,600 acres right in the center of where i run cattle that is open for use by everybody and all animals.
might be different in the mountain states.
