ABSTRACT 



Considerations guiding the design of a forest inventory for pro- 

 viding "in place" data for planning and programing timber manage- 

 ment are discussed. A design is described for an inventory intended 

 to be transitory between previous inventories that provided estimates 

 only of forest totals and later inventories that could use a complete 

 forest record of "in place" data. This inventory procedure uses field 

 examination of stands in sample subcompartments augmented by 

 aerial photo interpretation of conditions in compartments and sub- 

 compartments not examined on the ground. The data are compiled to 

 provide timber information that can be stratified with respect to land 

 use zones, size of stand, accessibility, land stability, productivity, 

 and by restrictions imposed by competing uses. Estimation formulae 

 for totals, means, and their variances are provided for the design 

 being discussed.
