Forest Management of Loblolly Pine 



Scope of Forest Management and its Advisability. Forest man- 

 agement deals with the handling of forest land to be held continuously 

 as such. The land and the growing stock of trees are considered in the 

 nature of principal, and the annual increment put on by the growing 

 stock as interest. The wood increment is allowed to accumulate until 

 the trees composing the growing stock are ripe for the ax. With the 

 harvesting of the mature timber, the growing of a new stock of small 

 seedlings is secured by one of two ways: (1) Removal of the ma- 

 ture trees in such a way as to accomplish the reproduction by natural 

 seeding. The superior reproductive power of loblolly pine makes it 

 more adaptable to natural reproduction than other pines, and, in fact, 

 than the majority of other species. (2) Sowing or planting the area 

 subsequent to cutting. This involves considerable financial outlay, but 

 will often te wise in cases where well-stocked stands cannot be secured 

 by natural reproduction. 



In ordinary lumbering the future growing stock is not considered, 

 and it is entirely a matter of chance as to whether or not a new stand of 

 any value springs up, and even where this is the case the stand is much 

 inferior in quality to one grown according to forestry principles.
