Accelerated research to determine how and why a root rot fungus destroys an otherwise 

 thrifty young stand of Douglas-fir will provide measures to prevent losses like this. 



and handling; tree nursery operations; planting, thinning, and 

 pruning; and final harvesting, sorting, and transporting a variety 

 of timber products. Problems of the small woodland owner will 

 receive emphasis. 



2. Design and evaluate new and improved logging equipment espe- 

 cially adapted to protecting watershed values, such as overhead 

 cable systems that will permit extension of harvesting opera- 

 tions into steep mountainous country where soils may be highly 

 erodible. 



3. Develop and evaluate unique systems such as logging, pest con- 

 trol, or fire suppression by helicopter or other new principles 

 and devices that may benefit future timber production and 

 utilization. 



Forest Resource Economics and Marketing Research 



At every step in the complex process of producing, protecting, 

 and utilizing forest resources, the landowner or manager must con- 

 sider the costs and economic advantages of alternate methods of 

 organizing and operating his resource program. Administrators of 

 public forests must develop economically sound management policies. 

 They must have a sound basis for selecting alternative combinations of 

 resource uses that are necessarily based on sound biological principles 

 but also on favorable economic returns. Industrial foresters must 

 base their recommendations and practices on cost and return deter-
