THE REVISED DESIGN 

 FOR SAMPLING COMPARTMENTS 



In an effort to correct these deficiencies, we developed a different inventory 

 system for trial use beginning in 1970 on two National Forests, the Coeur d'Alene in 

 north Idaho, and the Lewis and Clark in west central Montana. Development of the 

 system was a joint endeavor of the Northern Region and the Intermountain Forest 

 and Range Experiment Station. While this system is new to the Northern Region, other 

 National Forest Regions or other forest owners or managers have probably used some of 

 the same principles or techniques. 



Objectives 



To support the timber management planning purpose of "providing orderly and sus- 

 tained guidance for developing the timber growing capacity of working circles," we set 

 the following specific objectives for the revised inventory design: 



1. To provide "in place" data, on timber management opportunities that can be 

 stratified by land use zones, size of stand, accessibility, land stability, produc- 

 tivity, and by restrictions imposed by competing uses. 



2. To provide "in place" data for immediate use in program development and 

 execution. 



3. To complete a timber land record system that augments the existing stand 

 examination so as to account for all the forested acres. 



4. To provide empirical information for the ecological classification of the 

 forest into habitat types (Daubenmire and Daubenmire 1968). 



5. To provide information on a stand basis that permits stands to be projected 

 into the future, at varying intensities of management, for both inventory and manage- 

 ment planning purposes. 



6. To meet the requirements of nationwide Forest Survey and to provide inventory 

 data compatible with other timber inventories.
