Description
Abstract. -- This study was implemented in northeastern Arkansas to compare the performance of planted bottomland tree species with and without tree shelters. Thirty-centimeter translucent polyethylene tree shelters were installed around approximately one-half of the seedlings. Survival and growth of Nuttall oak (Quercus nuttallii Palmer), willow oak (Q. phellos L.), bitter pecan (Carya x lecontei) and baldcypress (Taxodium distichum (L.) L.C. Rich) were evaluated during the eight years following planting. Hardwood species were planted on reclaimed agricultural land along recently disturbed borrow pits. Survival of Nuttall oak, willow oak and bitter pecan seedlings with tree shelters were significantly (P 0.05) higher than seedlings planted without shelters for the eight years of the study. Overall, tree shelters increased survival from 43 to 73%. No significant differences were found for mean tree height, stem diameter or diameter at breast height (dbh) during the eight years of the study. The higher percentage of resprouted seedlings protected by tree shelters, 74 to 76%, indicates that the tree shelters may help protect the young emerging shoots from desiccation and herbivory. Data in this study suggest that the seedlings protected by the shorter tree shelters are comparable to results found in previous studies using taller tree shelters. **********
