Abstract

Abstract The purpose of this study was to determine the effects of soil treatments (ST) [fertilized sand (control) vs. added amendments of 78 Mg ha−1 compost (1×), 156 Mg−1 compost (2×), 15 cm of topsoil (TS), and 1 × compost + TS]; and restored microtopography (MT; level, pit and mound) on young bald cypress [Taxodium distichum (L.) Rich] tree growth in a created tidal freshwater wetland in southeastern Virginia. The crown class and position of each tree was classified according to the Kraft system ten years after establishment along with morphometrics of height (HT), trunk diameter at 10 cm above the soil surface (DIA 10), tree diameter at breast height (DBH at 1.3 m), and basal trunk swelling factor (D diff = DIA 10 − DBH). Additionally, competition effects of all planted and successional woody vegetation on the planted bald cypress were evaluated. There were no effects of soil treatments on the measured parameters, but there were strong overall experiment-wide effects of MT. Diameter at 10 cm (DIA 10) and basal swelling (D diff) were significantly (P
