Counties. The scrub-hardwood type is a mixture 

 of stunted, low-quality hardwoods of little com- 

 mercial value, occurring where soil or moisture 

 conditions do not favor rapid tree growth. Such 

 stands are found in western Houston and Walker 

 Counties as well as in the eastern part of Liberty 

 County. A transitory form of this type also oc- 



curs on some of the clear-cut longleaf land, 

 particularly in the northern part of Tyler County. 

 Less than 200,000 acres were typed as scrub 

 hardwoods.

 types by topographic situations and also the

Table 3 presents the composition of the forest 

 type groups and the percentage of the net cubic 

 volume of the type group in each species. 



Forest Conditions 



On the basis of stand, age, and cutting history, 

 the forests fall into three broad conditions — old 

 growth, second growth, and clear-cut, as already 

 defined. For precision in classification these con- 

 ditions are subdivided in the following manner: 



(1) Old-growth uncut and old-growth partly cut; 



(2) second-growth sawlog-size uncut and partly 

 cut, second-growth under-sawlog-size uncut and 

 partly cut, and reproduction; and (3) clear-cut. 

 The respective areas falling in the three type groups 

 are given in table 4.
