In studying the damage cone to reproduction snail 

 plots of 1/5 acre caoli were ta"-:on in average stands ana. all 

 the trees tallioc. ""07 species, according to the coinage re- 

 ceived ~ Irille?., injured or uninjured - and according to 

 size classed ~ 6" high to 5 1 high, 5 T high to 4 n D.B.H., 

 4" D.3.E. to 12" D.3.H. 



The f oil owing results wore obtained: 



840 acres completely destroyed 31,600,000 ft. 



25,400 a. surface fires, 5.3$ destroyed 40,386,000 ft. 



Total stand 40,967 ft. 



52$ g 2.125 ft. injured for the first time 

 47,3$ = 19;3G7 ft. injury increased 



6.3$ ~ 2,161 ft. totally destroyed 

 4.E$ ~ 17,294 t'c . uninjured. 



This shows that during each fire a little over 5$ 

 of the stand receives its first injury, 47^ has former -in*-.. ., 

 ji'rios increased and 5'/j lias former injuries increased to the 

 o:rbent that the tree fal?s, since of the 6*3/3 of the stand 

 v ~re "burned throiTgh at the outt and ,6$ wore 



standing dead trees. 



It was also found that 6/5 of the stand of sugar 



pine wcis Irilloc, 11* 5; j of ;;ho stand of yellow pine, 16$ 



f 

 of the stand of white fir and 5.1$ of the stand of incense 



co. cr, showing that the yellow pine with its pitchy "butts 



to 

 receives the most injury. The tallies ta::on/show the damage 



to reproduction show that 75$ of all the reproduction was 

 hilled, 2.8$ was Injured and 22.2$ escapee injury.
