Within-species selection was chosen as the method to improve pitch pine for a seed orchard to furnish seedlings for revegetation in southern New Jersey. In a progeny test of 68 families of open-pollinated plus tree seedlings at two plantation sites, after 5 growing seasons the top family among selected pitch pine progeny was as tall as the best pitch x loblolly check stock, and the best five pitch families were in the same range with another pitchlob and two loblolly families. Mean heights were slightly greater on a worked-out sandpit site than on an undisturbed sandy topsoil. North. J. Appl. For. 11(4):146-149.
