Artifical Regeneration of Multiple Hardwood Species to Develop Specific Forest Communities
A five-species mixed hardwood plantation consisting of Liqudembar styraciflua, Quercus mmichauxii, Q. pegoda, Frexinus pennsylvenica, and Carya aquatica has been estsbllshed at the National Environmental Research Park, New Ellenton, SC. All were grown under uniform conditions with the same nursery fertility protocol. Individual trees for outplanting were chosen from approximately the best 50 percent of the nursery crop for each species based upon a combination of first-order lateral root characteristics, heights, and root collar diameters. All trees were free-to-grow at the end of the fifth growing season. Fifth year survival runs between 83 and 100 percent. Sweetgum and green ash are the largest with heiihts of 3.77 and 3.71 m and diameters of 4.53 and 3.08 cm, respectively. Sweetgum stem volume exceeds the others by 2-2014 times. All species are represented in the main crown canopy and the high vigor of most trees suggests this mixture can be maintained.
