' Includes roundwood harvested from growing stock and other sources such as salvable dead trees, rough and rotten trees; and trees on forest land other 
than timberland, in fence rows, and in urban areas. 
? Includes removals in the form of roundwood products, logging residues, the volumes of timber removed in cultural operations such as noncommercial 
thinning, and inventory losses resulting from the diversion of timberland to other uses such as cropland, pastureland, parks, and urban uses. 
3 All projections at equilibrium prices, i.e., the stumpage prices at which projected timber demands and supplies are equal (see appendix table 4.1). Data 
are averages for 5 years centered on the projection year. 
4 Data for 1952 and 1962 are as of December 31. Data for 1970 and all projection years are as of January 1. Data for 1976 and 1984 are as of January 1, 
1977, and January 1, 1985. 
Note: Data may not add to totals because of rounding.
