Grazing Investigations on Our National Forests 23 



It is understood that the character of the injuries and 

 the species in question were recorded in all cases. This 

 can not be shown without elaborate tabulations. It may be 

 said, however, that Sugar Pine and Western Yellow Pine are 

 the most palatable and consequently are more frequently in- 

 jured than any other species. Incense Cedar is only browsed 

 by goats, which, it should be added, are by far the most de- 

 structive class of stock to forest reproduction. As an example 

 of preference for species it may be mentioned that in the au- 

 tumn (second count) 62.54 per cent of Yellow Pine saplings 

 and seedlings and 10.12 per cent of Incense Cedar were browsed 

 on the goat ranges. 



This study on the relation of grazing to> the reproduction 

 of timber species has disclosed facts to show that goats are 

 seriously destructive, but that the presence of sheep and cattle 

 is not a serious matter to the reproduction of the young timber 

 growth. In many localities where serious injury has resulted 

 from sheep and cattle grazing, the injury is rather due to 

 faulty handling such as premature grazing or overgrazing. 

 Regulated grazing and good management are not liable to 

 prevent or destroy the subsequent establishment of our for- 

 ests, but when we think of the high value of grazing as pre- 

 venting the running of fires, I am strongly inclined to think 

 that moderate grazing should be encouraged.
