Releasing Pitch Pine Sprouts from Old Stools Ineffective
Abstract:In 1954 study treatments were started in Plains vegetation in southern New Jersey (1) to favor 400 selected pine sprouts per acre or (2) to convert to a pine stand of seedling origin. Poisoning all competing sprout clumps of pine and scrub oak doubled diameter growth of the selected sprouts, but did not increase height growth. After six years these stems gave little promise of ever developing into merchantable trees. To grow trees of merchantable quality in Plains areas, the present sprout stands apparently must be converted to seedling stands. Methods used in the course of this study suggest two possible ways of eliminating the present vegetation and preparing the sites for establishment of natural seedlings. One would involve mechanical clearing of strips with a bulldozer or other heavy equipment; the other would make use of chemical herbicides. Both methods would be supplemented with prescribed burning.
