APPENDIX 



The following table lists 237 range forage species tested in experimental plots for useful- 

 ness in seeding rangelands in southern Idaho. Plantings were made at one or more locations 

 each year during the period 1936 to 1955--by personnel of the Intermountain Forest and Range 

 Experiment Station prior to 1954, and by the Agricultural Research Service subsequently. 



Symbols in the table show a comparative rating of adaptability of these species for use on 

 six classes of sites commonly found in this area. Ratings should be regarded as indicative 

 rather than precise because of the variety of growing conditions within sites, the varied lengths 

 of testing periods , and the different methods of seeding used throughout the 2 decades of the 

 testing. 



We have rated adaptation of individual species to environmental conditions on a scale of 

 1 to 3 as follows: 



1 Adapted to the site and generally useful for range seeding in southern Idaho. 



2 Either (a) adapted to the site and useful for special conditions , (b) adapted , 

 but of little value for seeding southern Idaho rangelands, or (c) promising, 

 but not yet adequately tested. 



3 Failed to survive where tested, and presumed not to be adapted. 



Not tested for this site. 



* Recommended in this publication for range seeding. (Some species carry 

 this symbol in addition to either 1 or 2.)
