INTRODUCTION 



Repeated requests from field officers of the Forest Service for an accurate 

 publication, readily consumable under field conditions, in as simple language 

 as possible, which could be assembled as desired, and be easily revised, were 

 the genesis of this loose-leaf range-plant handbook. Its intended audience 

 is primarily busy field administrative men who are not specialists in botany; 

 its chief purpose is twofold: (l)To evaluate for such persons, in as succinct, 

 understandable, complete, and useful form as possible, the relative importance 

 of some 300 or more of the outstanding "key" plants of western ranges as 

 regards grazing, watershed protective cover, recreational, and other uses ; and 

 (2) to enable the ready field identification of these plants in order to insure 

 the correlation of the proper management data with each species.

 L. Pomeroy. 



2 It will be noted that there are certain gaps in the symbols for the write-ups of 

 individual genera and species included in this handbook. These gaps are explained in 

 the introduction which follows.
