Section 3.7-7 Hardwood Land. 



Primary or best hardwood producing land 

 normally consists of river bottoms, creek or 

 branch bottoms and hammocks. Such land is 

 usually characterized by a clay or silt soil, 



which is relatively well drained but subject 

 to periodic flooding. Species which occur nat- 

 urally are gums, oaks, bays, magnolia, ash, and 

 bald cypress. The following table indicates land 

 values where hardwood trees are predominant :
