BETTER RANGE MANAGEMENT. 



This bulletin presents the results of experiments which bear 

 directly on the problem of how to produce more and better cattle 

 on western range lands, a matter of pressing importance in view of 

 the present need for increasing the Nation's food supply. 



It is generally conceded that the carrying capacity of the remaining 

 areas of public range is at least 25 per cent less than it was originally, 

 the result of grazing stock at improper seasons and overstocking. 

 It is also a fact that the productiveness of many privately owned 

 ranges, both fenced and unfenced, has been reduced through faulty 

 management. To work out a system of range management and 

 improvement practicable for large grazing units, which will build 

 up the depleted areas and insure the maintenance of the whole range 

 in good condition, is one of the important objects of grazing studies
