The various type groups in the old-growth 

 condition occupy about 1 million acres, or 16 

 percent of the total forest area, divided into long- 

 leaf pine, 2; shortleaf-loblolly-hardwoods. 4: 

 and hardwoods, 10 percent. Most of the old- 

 growth uncut longleaf pine is found in large 

 tracts, some of which are several thousand acres 

 in extent. Partly cut stands more often exist as 

 small acreages of residual trees, scattered through- 

 out the second-growth stands. Old-growth stands 

 of shortleaf-loblolly-hardwoods usually occur in 

 scattered patches of a few acres each; continuous 

 bodies are rarely found. The old-growth hard- 

 woods prevail in large, unbroken areas along the 

 main stream bottoms. 



The second-growth condition includes all ages 

 of second-growth stands, from reproduction through

Figure 3. — Forest area in the various type groups and forest conditions 



the sapling stage up to and including saw timber 

 (fig. 1). These stands occupy about 81 percent of 

 the forest area, totaling over 5 million acres (table 

 4). By forest type groups, in terms of proportion 

 of the total forest area, this condition is classified as 

 longleaf pine, 9 percent; shortleaf-loblolly-hard- 



woods, 56 percent; hardwoods. 16 percent. Sec- 

 ond-growth stands occur throughout the unit in 

 areas ranging from a few acres to blocks of thousands 

 of acres. These second-growth stands, forming an 

 almost continuous cover over a great part of the 

 unit, characterize the forests of east Texas.
