cord increment of hardwoods, as of the year of the survey, 
it is estimated that more than half was in soft-textured 
species. 
Excluding the effect of cutting in all cases, the average 
net annual increments per acre in Georgia compare favor- 
ably with those in other States. In central Georgia in 
1936, the weighted average, with reproduction and clear- 
cut areas included, was 195 board feet of saw timber (table 
20), or two-thirds of a cord including bark for all growing- 
stock trees 5.0 inches d. b. h. and larger. This is one of 
TaBLe 20.—Average net increment per acre, excluding effect of cutting \

the highest average increments ‘per acre found in a 
survey unit in the entire lower South territory. Net 1 
crements in north-central Georgia were almost as great 
in north Georgia, where the sites are poorer, they were 
about half as high; and in south Georgia, where turpen- 
tining and fire retard the growth and increase mortality, 
about a third as high. As a general rule, the greatest 
average net increment per acre occurred in the uncut 
second-growth stands of sawlog-sized timber. Bi
