In 1953, the annual loss of merchantable timber This annual loss amounts to 2.4 percent of the 



from fire, wind, insects, disease, and miscellaneous growing stock and 1.5 percent of the .sawtimber 



natural cau.ses was estimated to be 194 million volume. It is 45 percent as large as the annual 



board-feet of sawtimber and 173 million cubic feet growth for all growing stock and about 25 percent 



of all growing stock: of the sawtimber growth (fig. 22).
