At least partially responsible for this decrease in 
the production of several forest products was the 
decline in timber volume which took place between 
surveys. These volume losses were confined almost 
entirely to the larger and better-quality timber. 
Practically all of the decrease in pine volume took 
place in the central and southern parts of the State, 
and, to a large extent, is attributable to clearing for- 
est land for crops and pasture. The volume of pine, 
hardwood, and cypress pole timber increased, but not 
enough to offset the decline in saw timber. All in all, 
the 1949 survey revealed a 9-percent drop in the 
volume.of all timber 5.0 inches and larger. 
The amount of young timber increased, largely 
as a result of improved forest practices. However, a 
large part of this increase took place on a relatively 
small area, much of which was already well stocked. 
At the same time, losses due to timber mortality 
dropped. Better fire protection has permitted large 
areas to restock. The smaller number of trees worked 
for gum, the virtual elimination of the practice of 
working trees under 9.0 inches, and the utilization of 
small worked-out timber for pulpwood have reduced 
pine timber mortality to 14 percent of what it was 
in 1936.
