MANAGEMENT OF SHEEP ON THE RANGE. 



CONTROL. 



Control over the number and distribution of stock is a fundamental 

 requirement of effective range management. Control of the number 

 of sheep entering a National Forest or any large range unit of the 

 Forest is comparatively simple. The sheep are under a herder and 

 can be counted in at the Forest boundary and be driven to a range 

 unit in a given time over an established route. On the unfenced 

 sheep ranges of the public domain such control is lacking ; and, as a 

 consequence, these ranges are run down and in many places are still 

 deteriorating. 



On ranges of the National Forests the problems in sheep manage- 

 ment are: (1) To establish range sheep units; (2) to get the sheep 

 on these units with the least damage to the range ; (3) to prevent tres- 

 pass from one range unit to another; and (4) to see that the sheep are 

 so handled as to secure uniform distribution of grazing and full 

 utilization of the forage. 



ESTABLISHING SHEEP EANGE UNITS. 



In general, the practice on ranges within the National Forests has 

 been to divide the sheep range into units which will furnish sufficient 

 forage for a band of sheep during the established grazing period. In 

 some cases the range unit, or allotment, includes range for several 

 bands of sheep owned by one permittee. 



The assignment of an individual range to each band places respon- 

 sibility for proper use of the range squarely upon the individuals
