Palatability and Tolerance to Grazing 



Palatability is important where there are two or more species in the same grazing area. 

 Unless they are similar in palatability, the more palatable will suffer from heavy use (fig. 6). 

 If stock are forced to eat only a moderate amount of the less palatable, the more palatable 

 species is weakened. 



Some species are better adapted to surv'ive heavy grazing than others, but productivity of 

 any species is reduced by continued heavy use. 



SPECIES FOR SOUTHERN IDAHO RANGES 



From more than 250 species and strains tested on a variety of sites in southern Idaho, 

 enough have been found to fit almost all kinds of sites needing revegetation from the low- 

 rainfall areas to the high mountains. Recommended species are listed in table 3. A complete 

 list of species tested in southern Idaho is in the Appendix. Further information about species 

 characteristics is given by Hafenrichter et al. 1949; Plummer et al. 1955; Stark et al. 1950; 

 and Weintraub 1953.
