Bottom-Land Hardwood Forests 



Louisiana has 7,627,300 acres of bottom-land hardwoods, 

 more than any other State of the lower South. Seventy- 

 six percent is in the alluvial lands of the Mississippi River 

 Delta, the remainder chiefly in the bottoms of the Red, 

 Ouachita, Calcasieu, Sabine, and Pearl Rivers and other 

 streams of the rolling uplands. 



Typically, these hardwood forests contain a dominant 

 stand of overmature trees, with an understory of immature 

 trees of varying sizes and ages (fig. 5). In such a forest, 

 industrial cutting operations usually remove only the 

 larger and higher-quality trees, leaving well-stocked stands 

 of immature trees of varying ages and mature trees of the 

 species less desirable for industrial use (fig. 6). 



Of the 36 percent of the bottom land that still bears 

 old-growth timber, nearly half is in the north delta unit. 

 On approximately three-fifths, high-quality timber has 

 been cut for lumber, veneer, and cooperage stock. About 

 35 percent of the bottom-land forest area is taken by second 

 growth stands that have reached sawlog size, and 26 per- 

 cent by other second-growth. More than half of the 

 second-growth area is in the south delta unit. Only about 

 3 percent of the bottomland forest area is classed as clear-
