  • a A characteristic is followed by an asterisk when the means were significantly different (P ≤ 0.01) for bottomland (B) versus upland (U) sites.

  • b DBH, diameter at breast height.

  • c OM, organic matter.

  • d Values in parentheses represent standard deviations of 3 measurement replicates.
