boled, produced lumber of dense grain and high quality. 

 The original pine forests of the southeast were essentially 

 similar, except that slash pine often occurred in associa- 

 tion with longleaf pine. 



The longieat-slash pine types still characterize more 

 than 2^2 million acres of the upland forest area but are 

 gradually losing ground. They are being replaced by 

 loblolly pine, which produces seed more frequently and 

 abundantly than longleaf pine and germinates better under 

 existing seedbed conditions. This extension of loblolly 

 pine is particularly evident in Natchitoches and Sabine 

 Parishes in the southwest pine unit, and is common also 

 in the southeast pine unit. 



Ol the present longleat-slash pine forest area only 3 

 percent supports uncut old growth. Most of this is in 

 Rapides and \'ernon Parishes and is held by large com- 

 panies. Partly cut old-growth stands occupy 5 percent 

 of the area. Second-growth stands have reached sawlog 

 size on 11 percent of it, and second-growth stands under 

 sawlog size occur on 32 percent. The remaining 49 per- 

 cent of the type-group area, mostly in Vernon, Beaure- 

 gard, Rapides, Allen, and Calcasieu Parishes, has been 

 clear cut and so seriously damaged by fire and grazing 

 that practically no reseeding has taken place. 



Occasionally the clear-cut areas occur as large barren 

 blocks with practically no seed trees or reproduction 

 (fig. 8). More commonly, they contain a few scattered 

 seed trees or potential seed trees (fig. 9). In southwest
