FORAGE PLANTS: COLLECTION, IDENTIFICATION, AND NOTES. 



Familiarity with the Tegetation which produces the forage crop 

 on range lands is essential to their efficient management. Xearly 

 ever}^ phase of range management is intimately associated with a 

 knowledge of the range plants, their forage value for different classes 

 of stock, and their requirements. 



In determining the class of stock to which a range is best suited, 

 character of forage is the first factor to be considered. In other 

 words, the administrator of a range must have an accurate working 

 knowledge of the plants on that range before he is in a position to 

 decide the class or classes of stock to which the range is best suited. 



The permanent welfare of the range is the fundamental principle 

 in deciding the grazing period. At the same time it is important, so 

 far as is consistent with normal utilization of the whole range and 

 perpetuation of the desirable species, to utilize the plants at the 

 periods of their highest palatability and nutritiveness, the latter
