. Lumber grade yields from paper birch and balsam poplar logs in the Susitna River Valley, Alaska. Lumber Mensuration; Paper birch Alaska Susitna River Valley; Poplar Alaska Susitna River Valley. Lumber grade yields and overruns by log grade and scaling diameter were determined for 162 paper birch and 174 balsam poplar logs from Alaska. The information obtained will be useful for timber appraisal and, when coupled with the saw-log volume and quality informa- tion contained in the preliminary Susitna Valley Forest Survey report,5 could have impli- cations for industrial development.

This study has shown that Forest Service standard grades for hardwood logs are adaptable to birch and balsam poplar in Alaska. However, additional recovery information is required for grade I birch logs. Grading rules of the National Hardwood Lumber Association also proved to be well suited for use with these species. Those who desire to pursue further the economic aspects of a hardwood industry in Alaska are directed to a recent report from the University of Alaska's Institute of Social, Economic, and Government 5See footnote 2. 6Massie, Michael R.
