Colorado Revised Statutes Title 35. Agriculture § 35-45-101. Determination of grazing rights

To prevent dissension and breach of the peace, the question as to the kind of livestock, whether cattle or sheep, that shall have the preferred or better right to graze upon any particular portion of the public domain within this state shall be determined according to the use made thereof during the last grazing season, whether such use was as cattle or sheep range and whether the same was used as a spring, summer, fall, winter, or other kind of range; but a single instance of grazing or herding certain kind of livestock on any such range over the protest of others in prior use and occupancy thereof, who graze a different kind of livestock, will not confer a better right.
