RESEARCH 



The Government's forest work does not end with the administration 

 of the national forests. Among other things, the Forest Service con- 

 ducts many investigations designed to promote the best use of the for- 

 ests of the United States, whether in public or private ownership. 

 Some of these investigations concern the growth, management, and 

 protection of forests, and others the utilization of their products. 

 Studies of economic problems involved in forestry, and of manage- 

 ment of range lands for livestock grazing, are also made. 



Through the 12 regional forest and range experiment stations main- 

 tained by the Forest Service, intensive studies are made of such things 

 as the rates of growth and yields of the different tree species; what 

 methods of cutting under varying conditions will be followed by 

 the best reproduction of the most desirable kinds of trees; the best 

 methods of nursery practice and of tree planting; and how best to 

 protect the forests from fire and other damaging agencies. The re- 

 lation of forests to climate, stream flow, and erosion is also investi- 

 gated, and studies are made of range conditions and management. In 

 this work the stations cooperate closely with the national-forest or- 

 ganization, with other Government bureaus, State foresters, and 

 agricultural colleges, experiment stations, and universities.
