LOBLOLLY OB NORTH CAROLINA PINE. 13 



stands on the hills near the rivers and is gradually extending away from 

 the streams, in spite of the increasing dryness of the soil. 



The growth in the old fields along the eastern edge of the Piedmont 

 plateau in many places is nearly pure loblolly pine. Where young trees 

 of the shortleaf pine appear they are often overtopped and suppressed, 

 being outnumbered and overgrown by the loblolly pine. To the west- 

 ward, however, there are fewer seed trees, and where there is competition 

 between the two species, the shortleaf pine has the advantage, except on 

 moist or sandy soils. 



ASSOCIATED SPECIES. 



With such a wide range of soil adaptability loblolly pine is associated 

 with many species and is a component of many forest types. In" the 

 mixed stands in the swamps and on poorly drained sites some of the 

 associated species are fully as valuable as the pine and are well adapted 

 to silvicultural purposes. Other species are less valuable than the lob- 

 lolly. The following list gives the most important associated species.
