Book Description
Excerpt from Loblolly Pine Seed Tree Mortality, Vol. 6 The 8 best seed-producing pines, or one-quarter of the pine stands, were left to reseed each acre when the timber was harvested from mature stands. Crawler tractors were used in logging. Cultural operations designed to improve the seedbed and reduce competition from undesirable plants were used on some of the areas. One-half of the logged areas were burned and one quarter disked to improve the seedbed. Some seed trees were injured during the logging and in the burning operations. Eight percent of the seed trees were severely damaged in logging and 5 percent of the injured trees died. A record of mortality showed that less than 1 percent of the seed trees died per year for all seed-tree areas during the average regeneration period of years. The increased seed-tree mortality due to the burning treatment was approximately equal to the average lightning mortality for the period. A number of trees died with no external evidence of injury. Lightning and wind caused over half the mortality during the period the trees had to stand to re seed the area.

Book Description
Excerpt from Growth, Mortality, and Regeneration After Cutting in Loblolly Pine Pulpwood Stands Good forest management policy today would not accept the rather crude short-rotation cutting methods as practiced in this early study. New methods of seed-tree selection and stimulation, seedbed preparation, and control of inferior understory species are some of the techniques considered advisable to secure satisfactory regeneration. However, there are large acreages of loblolly pine stands not under intensive management which are still being cut by some of the methods practiced in this study. The records of growth, mortality, and regeneration during the 9-year period following cutting by the six methods tested provide some useful information regarding these stands.

Book Description
Excerpt from Influence of Loblolly Pine Overwood on Advance Reproduction At sporadic intervals, perhaps once each decade, a favorable combi nation of loblolly seed production and rainfall distribution occurs in the lower Piedmont region, with the result that pine seedling stands become established beneath overwood stands of loblolly pine. The majority of these understory pine stands are found on the flat ridge tops and on gentle to moderate slopes of southerly and westerly exposures. This advance reproduction occurs in more or less uniform age classes over contiguous areas from a few acres to as many as 100 acres, depending upon the uniformity of the topography. The overstory stands may have a stocking of 120 square feet of basal area per acre and still have a solid understory stand of loblolly pine (fig. Advance pine reproduction may also become established underneath stands as young as 20 years of age Where the overwood is less than 60 square feet of basal area (fig. The occurrence of loblolly pine reproduction as an understory has great potential value to the landowner. He has only to give it reasonable care to insure the establishment of his future stand or parts of it. Regardless of the. Landowner's method of management, thousands of acres of seedlings become established in advance of the planned reproduction cut. This applies whether the stand is to be reproduced by leaving seed trees, or by the shelter wood method, or in openings created by selective cutting, or even where the plan Specifies clear cutting and planting. Where this advance reproduction is present, the owner will not have to wait several years for the right combi nation of seedfall and rainfall, nor bear the expense of planting. In an effort to realize more fully the potential of this advance reproduction, a study was begun to determine the conditions under which these seedling stands become established and maintain themselves, and to determine the growth rates of the seedlings.
