PREFACE 



This publication summarizes available information and experience to 

 serve as a guide to range seeding. Recommendations are based primarily 

 on results of experimental seedings made since 1936 in southern Idaho. 

 More than 230 species have been planted in more than 13,000 plots at 79 

 locations. Many large-scale seedings have been observed to check the 

 soundness of recommendations for species, methods, and management 

 practices. Locations of the experimental and large-scale seedings are 

 shown on the map inside the front cover. Results of some of the research 

 have been published previously. This publication reviews published 

 information and presents additional information previously unpublished. 



The studies were planned to determine adapted species and to develop 

 effective methods of seeding southern Idaho rangelands. Many of the seed- 

 ings were grazed. They show the relative palatability and grazing tolerance 

 of individual species. The studies and large seedings have shown that 

 seeding can be a profitable investment. 



Much of the work reported here was cooperative with ranchers. 

 Cooperating agencies included the Agricultural Research Service, Soil 

 Conservation Service, and Forest Service, U.S. Department of Agriculture; 

 the Bureau of Indian Affairs, and Bureau of Land Management, U.S. 

 Department of the Interior; and the University of Idaho.
