Grazing Investigations on Our National Forests 15 



It is fairly drought resistant and yet it can be depended upon 

 to make a good stand in moist meadows. 



Judging from the experiments, the most promising cultivated 

 species for range reseeding on the lands studied, naming them 

 in order of their importance, are timothy, Hungarian brome, 

 Italian rye, red top, Kentucky bluegrass, alsike and white 

 clover, orchard grass, tall meadow oat grass, Canadian blue- 

 grass and hard or sheep fescue. In all cases, except in parts 

 of the Southwest, as on the Coconino National Forest, fall seed- 

 ing has given much better results than sowing in the spring. 



Since the inauguration in 1909 of carefully planned ex- 

 periments in forage reseeding on the National Forests, not 

 including the recently initiated experiments in 1911, 329 re- 

 seeding plats have been established and reported upon. Of 

 this number 111 or 33.8 per cent have been successes or partial 

 successes and 123 or 37.4 per cent have failed. The remain- 

 ing experiments have either not been reported or the results 

 are still uncertain. 



The causes of failure are shown in the following table : 



NATURAL HEVEGETATION OF THE RANGE. 



The very term "revegetation" when used in connection 

 with range lands presupposes a reduction in their former 

 productiveness. It is natural to presume that during the initial
