The authors acknowledge with appreciation the work of K. N. Boe, 

 R. K. LeBarron, A. L. Roe, A. E. Squillace, and D. Tackle for 

 designing and establishing these studies and collecting much of the 

 field data. We are indebted to the Bitterroot, Kootenai, and Lolo 

 National Forests; St. Regis Paper Company; and the Anaconda 

 Forest Products for their cooperation and use of their lands. On 

 areas used for study of natural regeneration, R. D. Pfister de- 

 scribed the plant communities and assigned habitat types and R. C. 

 McConnell determined the general geology and soils information.
