Drought Hardy Tests of Loblolly Pines

During 1951, a study was initiated to determine if drought hardy strains of pine could be found that would improve survival and growth on droughty planting sites. Need for this work is critical, especially in the Western Gulf Coast Region where there have been widespread plantation failures as well as losses in older plantings in dry years such as 1951 and 1954. Some landowners have about given up planting as a hopeless task. Although it is hard to get a stand of pine trees started on these critical areas, once the trees are well established their growth rates ,and the per acre yields are very satisfactory.
