tered singly or in small groups throughout 18 million 
acres of sapling and pole stands and poorly stocked areas.

The Timber Supply Situation in Florida 
are shown in table 7. Only 12 percent of the hard- 
wood volume is in select and Grade | logs. A third 
of it is in Grade 3A logs which will yield mainly 
poor-quality lumber, and over another third is in 
Grade 3B logs which are primarily suitable for cross 
ties and construction timbers. 
Florida’s timber supply is concentrated in the 
northern part of the State. With 63 percent of the 
commercial forest area, Northeast and Northwest 
Florida together have 80 percent of the State’s saw 
timber and 78 percent of all growing stock. 
The intensity of commodity drain on the timber 
supply likewise varies in different parts of the State. 
In 1948, it varied from 8.1 percent of the growing 
stock 5.0 inches d.b.h. and larger in Suwannee 
County to less than 1.0 percent in several counties— 
mainly in the lightly timbered counties in the south- 
ern part of Florida (fig. 12). Five counties, Suwan- 
nee, Duval, Pasco, Hillsborough, and Marion, with 8 
percent of the growing stock in the State sustained 
18 percent of the commodity drain.
