accurately located and described, the most practical remedy 

 is to manage the grazing so that the forage species will have 

 an opportunity to seed. This can be accomplished by short- 

 ening the grazing season, by rotating the movement of sheep 

 so that they will not graze on the areas to be protected until 

 the seed has matured. If a certain class of stock is respon- 

 sible for overgrazing, this class of stock should be shifted to 

 other allotments. Reseeding artificially should be tried and 

 promising exogenous species introduced. 



(3) How to prevent serious damage to young forest 

 growth. As soon as the special studies determine the extent 

 of damage, the class of stock mainly responsible, and the 

 conditions under which severe injury is done, steps should 

 be taken to remove the causes of serious injury. It is prob- 

 able that the measures proposed to secure the best distribu- 

 tion of stock over a range will serve largely to do away with 

 the serious damage to forest reproduction. 



(4) How to minimize the danger from poisonous plants. 

 This is a problem which deserves emphatic treatment. The 

 spread of poisonous locos, milkweeds, the pingue, and sev- 

 eral other obnoxious weeds over some of the ranges well 

 supplied with forage and water has greatly reduced the prac- 

 tical value of these ranges and threatens to become a very 

 serious menace to grazing not only upon the forests but 

 upon all the higher ranges in the state. The eradication of 

 these objectionable plants is properly a problem for the 

 Bureau of Plant Industry, but the Forest Service with de- 

 tailed information as to location, abundance, and habits of 

 these plants on the various forests will be in a position to 

 cooperate in any plan to exterminate them. Stockmen will 

 be advised as to the areas infected, the periods when the 

 different plants are apt to injure stock, the seasons when 

 the stock may safely graze infected areas, and any prevent- 

 ives and methods of handling stock whereby the danger from 

 poison may be minimized. 



Judging from the state of public opinion, which has 

 changed from one of unfriendliness to one of approval and 

 cooperation toward the grazing administration of the forests 

 in Arizona, it is reasonable to suppose that these ranges will 

 continue under government regulation. In fact, it is entirely 

 probable that the essential features of this control will be 

 extended to all public ranges within the state.
