 usable crops of wood; (b) economically available now 

 or prospectively; and (c) not withdrawn from tunber 

 utilization.

 mercial timber use through statute, ordinance, or 

 administrative order. 



Tree Groups 



Softw^oods. — Pine, principally loblolly (Pinus 

 taeda) , shortleaf (P. echinata) , longleaf (P. palustris) , 

 and slash pine (P. caribaea) . Also baldcypress, or 

 "cypress" of the trade, {Taxodium distichum and 

 T. ascendens) and redcedar {Juniperus virginiana) . 



Hardwoods. — Broad-leaved species, of which the 

 most numerous groups or species are the white oaks 

 {Q,uercus, subgen. Lepidobalanus spp.), red oaks 

 {Quercus, subgen. Erythrobalanus spp.), hickories 

 {Carya spp.), sweetgum {Liquidambar styraciflua) , 

 and black and tupelo gums {Nyssa spp.) . 



Forest Type 



Forest type is determined only from dominant and 

 codominant growing stock and dominant and codomi- 

 nant smaller sound trees of good form. 



54 



LoBLOLLY-SHORTLEAF PINE. — Stands in which pines 

 comprise at least 25 percent of the trees, and at least 

 half of the pines are loblolly and shortleaf pines. 



LoNGLEAF-SLASH PINE. — Stands in which pines 

 comprise at least 25 percent of the trees, and at least 

 half of the pines are longleaf and slash pines. 



Cedar. — Stands in which eastern redcedar com- 

 prises at least 25 percent of the trees. 



Bottom-land h.ardwood. — Stands in which bot- 

 tom-land hardwoods and cypress comprise 76 percent 

 or more of the trees. 



Upland hardwood. — Stands in which upland hard- 

 woods comprise 76 percent or more of the trees, and 

 no pine is present. 



Upland hardwood-pine. — Stands in ^vhich upland 

 hardwoods comprise 76 percent or more of the trees, 

 and some pine is present. 



Class of Timber 



Growing stock. — Sawlog gro\\ing stock is the saw- 

 log portion of sawlog trees. Total gro\\ing stock in- 

 cludes sawlog gro\ving stock, and upper stems of soft- 

 wood sawlog trees and entire stems of cordwood trees 

 to a minimum top diameter of 4 inches inside bark. 



Saw^log tree. — A live, merchantable softwood 9.0 

 inches d. b. h. or larger, or a live, merchantable hard- 

 wood 11.0 inches d. b. h. or larger. To be merchant- 

 able, the tree must have at least a merchantable 12-foot 

 butt log or 50 percent of its gross volume in merchant- 

 able logs. 



Cordwood tree. — A live tree 5.0 inches d. b. h. or 

 larger, which, though now smaller than sawlog size, 

 would become a sawlog tree if it should grow to sawlog 

 size. 



Cull tree. — A live tree 5.0 inches d. b. h.. or larger 

 which, because of decay or sound defect, fails to meet 

 the specifications for a cordwood or sawlog tree.
