percent of the total by 2020. On these publicly 

 owned forests production of timber is only one of 

 several management objectives. With the growing 

 concern over the appearance and quality of the 

 outdoor environment throughout the country, 

 the public may call for further modifications in the 

 management of these lands that would be in- 

 consistent with the assumptions used in these 

 projections. Also, a large proportion of the surplus 

 growth on southern National Forests occurs in 

 hardwood stands in the rugged southern Appalach- 

 ians on sites of relatively low quality. Hence, 

 projections of products output based on the 

 assumption that removals will equal growth by 

 2000, may be overstated. 



Roundwood harvests per acre. — Production of 

 roundwood varied widely by ownership in 1970. 

 Output from forest industry lands averaged 37 

 cubic feet per acre, compared to 28 cubic feet for 

 farm and miscellaneous private holdings, and 12 

 cubic feet for National Forests (table 46) . 



Roundwood production for all owners combined 

 is projected to increase from an average of 28 

 cubic feet per acre in 1970 to 50 cubic feet by 2020 

 under the assumption of 1970 management. 

 Forest industry and National Forest lands are 

 expected to support the largest available harvests 

 per acre — approximately 56 cubic feet by 2020, 

 compared to 47 cubic feet for farm and miscel- 

 laneous private ownerships.
