tification of range plants, and the systematic elim- 

 ination of poisonous range plants and predatory 

 animals. 



Grazing reconnoissance is a stock taking of the 

 forage possibilities of a certain piece of range land. 

 This work is usually done by organized parties, 

 but a small amount is done also by Forest officers in 

 spare time. This study aims to collect all the im- 

 portant grazing information, such as: the area of 

 grazing lands, the kind of forage, the species of 

 forage plants, the location of streams, springs, and 

 other watering places for stock, the location of 

 stock driveways, drift fences, and cabins, the loca- 

 tion of timber lands that do and those that do not 

 contain forage, and many other matters pertaining 

 to the grazing of stock. The maps and field data 

 secured furnish the basis for range improvement 

 and more intensive range management. Up to 

 date, over 12,288,885 acres of range lands have 

 been covered in this way. 



All intensive forage and range experiments are 

 conducted at the Great Basin Experiment Station 

 on the Manti National Forest. Here intensive 

 problems are carried on under controlled condi- 

 tions and under constant and careful observation
